New, interesting problems and challenges are regularly being posed to the cloud community, including IT practitioners, managers, governments, and regulators. From Wikipedia, the free encyclopedia Cloud computing architecture refers to the components and subcomponents required for cloud computing. Since all data is located at one place, one must be careful in storing data in community cloud because it might be accessible to others. It helps in the team activities and group efforts, as the users can add, edit or update the information at any time in a simultaneous manner. Public cloud providers tend to implement best practices and try to ensure security at every level of the security stack. There are four main Cloud Computing deployment models: public, private, hybrid, and, Web Services, Service-Oriented Architectures, and Cloud Computing (Second Edition), Robotics and Computer-Integrated Manufacturing, Cost of building the datacenter on service consumer, Varies depends on the number of cooperatives, Operation and maintenance cost on the provider, Lowest cost with respect to the datacenter size, Highest cost with respect to the datacenter size, Weighted average, depending on the percentage of public and private parts, Similar to private clouds, but the cost divided on the participants, ∼15,000 more than private cloud but much less than public cloud, Infrastructure controllability and flexibility, Full controllability over the private part and limited for the public part, High controllability but limited by the community policies, The laaS vendor owns the public part and the consumer owns the in-house part. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Security is such an important concern that you need to go with what you trust. Environmental sustainability. This allows you to tune everything for best performance and usability. Private Clouds are accessible only internal to the organization, public clouds can be accessed by anyone with a login credential for the cloud, and third-party clouds are created & maintained by third party while being accessed by the client’s users. In a sense, the solution is more of a community cloud than a public cloud. Community clouds can provide a shared environment where services can facilitate business-to-business collaboration and offer the horsepower in terms of aggregate bandwidth, CPU, and storage required to efficiently support media production. The top stack represents user applications, or referred to SaaS, that deliver cloud applications to CSU. Security in terms of confidentiality, secrecy, and protection of data in a cloud environment is another important challenge. In these sectors, community clouds can bundle the comprehensive set of solutions that together vertically address management, deployment, and orchestration of services and operations. Sovereign Cloud Stack (SCS) is cloud technology built entirely with Open Source Software -- as an alternative to propietary cloud technology. Your can now test the 7.4.1 M3. Table 1 shows a comparison between the different cloud deployment models, based on the initial cost of building the cloud datacenter or the capital expenses (CapEx) on the consumer, the operating expenses (OpEx) and maintenance cost of the datacenter, the size of the datacenter, controllability and flexibility, the level of trust, the location of the infrastructure, and who owns the infrastructure. Like any other enterprise element, Community Cloud also has its own advantages and disadvantages, and the below are some of them. A virtual private cloud involves some type of partitioning to ensure that the private cloud remains private. Application services are the middleware services based out of the production systems designed and functioning specific to the application’s motives. Furthermore, regulatory compliance is a main obstacle facing community cloud adoption. This session would cover some of the patterns which could be used while architecting the solutions on Cloud. Nurul Hidayah Ab Rahman, Kim-Kwang Raymond Choo, in The Cloud Security Ecosystem, 2015. Explore the architecture and dive into the inner workings of our analytics database. For any organization to maintain the already built cloud application, they need to have a team of IT professionals focused and dedicated for cloud maintenance activities. In this, the service provider makes resources which can be virtual machines, application or storage for the public by the means of internet. Most people believe that the hybrid cloud model is the model that will be used in most organizations. Table 5.1 outlines SaaS provider responsibilities. Though it’s a cloud-based method, this costs more than typical cloud access, as it can cost based on the organization type and the number/ type of users. Community to share and get the latest about Microsoft Learn . Nearly all of the services used by the VPA in the story about C. R.’s trip are also in the public cloud. The national security information classification scheme is very mature and quite effective in managing control over and access to classified information. As cloud migration continues to evolve, hybrid architectures that enable companies to take advantage of both on-premises and cloud resources are a valuable tool. Google Cloud Community tutorials and events. This can also be called an internal cloud. There are several different ways cloud computing is made available for use. Community. It depends on the organization’s motive and method for handling their data. By the deployment environment, we mean the physical location, the infrastructure facilities, the platform constraints, as well as anything that can affect the access mechanisms of the deployed applications. For example, while the ratio between IT staff to servers is (1:100) [15] in traditional datacenters, this ratio goes to (1:1000) [15] and even (1:5000) in public cloud datacenters. It is usually implemented on the applications used for people management based organizations, like academic, banking, finance, social media platforms, etc. For example, in the Infrastructure-as-a-Service domain, how many resources need to be provisioned, and for how long should they be used, in order to maximize the benefit? From an architectural point of view, a community cloud is most likely implemented over multiple administrative domains. Table 5.2 outlines PaaS provider responsibilities. This can be another key factor in your decision. Community cloud: A community cloud is more restricted than a public cloud. It’s even more complicated when you’re dealing with the cloud. However, you still must consider which model is best for your organization. This explains why consumers trust the private cloud model more than the other models. Moreover, these clouds tend to be more organic by growing and shrinking in a symbiotic relationship to support the demand of the community, which in turn sustains it. This model has tremendous potential for entities or companies that are subject to identical regulatory, compliance, or legal restrictions. The following diagram shows the graphical view of cloud computing architecture: Front End In reality, this is a somewhat ambiguous term since an organization might have a private cloud and use the public cloud. Cloud Architecture Patterns. The promise of community clouds is that they allow multiple independent entities to gain the cost benefits of a shared nonpublic cloud while avoiding security and regulatory concerns that might be associated with using a generic public cloud that did not address such concerns in its SLA. This webinar features a conversation about key patterns, including detecting failures, and recovering quickly and efficiently, necessary to maintain resiliency. The idea of a heterogeneous infrastructure built to serve the needs of a community of people is also reflected in the previous definition, but in that case the attention is focused on the commonality of interests that aggregates the users of the cloud into a community. It lets the users to communicate and collaborate with other users/ team members that are operating under one cloud. This is managed by participating organizations or third party. Community cloud provides an infrastructure to share cloud resources and capabilities among several organizations. In a community cloud, a number of organizations, which usually share some common goals or belong to a specific community, build a shared cloud datacenter that can be used by all of the members. In both cases, the concept of community is fundamental. Organizations can implement their own policies with regards to privacy, security, and access mechanisms. 251 252 In Community Cloud deployments, infrastructure is shared by organizations that have common 253 interests (e.g. Indian Banking Community Cloud architecture. The underlying hardware is usually chosen by the cloud provider and not the users of the service (here you will likely find virtualization and device independence). Each environment (Sandbox, Dev… It provides greater flexibility and convenience for the users, to manage and work on their data. One for the Business Intelligence or Planning system. In cloud computing, there are four deployment models (i.e., private cloud, public cloud, community cloud, and hybrid cloud) and three architectures (i.e., Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS)) (Mell and Grance, 2011). However, it is important to note that the level of trust is not related to the actual security level. DOI: 10.1145/3288599.3295594 Corpus ID: 57760682. As shown in Table 1, there is no initial cost associated with adopting public cloud by consumers [12]. Onde: Índia. However, having both public and private clouds working together requires interoperability and portability of both applications and data to allow communication between the models. In particular, community clouds can provide a global platform on which to share information and knowledge without revealing sensitive data maintained within the private infrastructure. Carolyn J. Sher DeCusatis, Aparicio Carranza, in Handbook of Fiber Optic Data Communication (Fourth Edition), 2013. DOI: 10.1145/3325112.3325229 Corpus ID: 190230577. Cloud Architecture for Resiliency Resiliency is the ability of a system to gracefully handle and recover from failures. Technical challenges also arise for cloud service providers for the management of large computing infrastructures and the use of virtualization technologies on top of them. This is a different scenario than public clouds, which serve a multitude of users with different needs. As any new technology develops and becomes popular, new issues have to be faced. IaaS is formed from the underlying system infrastructure and core middleware. Read more Study Group XII: Community … Different legislation about privacy in different countries may potentially create disputes as to the rights that third parties (including government agencies) have to your data. Architecting for a cloud and mobile-first world More than ever, enterprises are relying on architects to help them embrace digital transformation. Organizations having similar computing concern and have shared interest can share it. That sort of information classification would lend itself to a public cloud, to hybrid cloud processing, or to a community cloud. This type of cloud computingis best compatible with ventures, business organizations, research organizations, and tenders. Figure 4.6 provides a general view of the usage scenario of community clouds, together with reference architecture. Community clouds are distributed systems created by integrating the services of different clouds to address the specific needs of an industry, a community, or a business sector. The VPA itself is in the public cloud as well. If you go with a public cloud, in some cases you might have no control over the user experience. These are specifically tied to the ubiquitous nature of cloud computing, which spreads computing infrastructure across diverse geographical locations. In the media industry, companies are looking for low-cost, agile, and simple solutions to improve the efficiency of content production. If you want to learn more about Enterprise Cloud Architecture, please reach out our sales team here . It is clear from Table 1 that consumers can have full control over a private cloud infrastructure, whereas in a public cloud, controllability is limited to tuning some configuration parameters. The contents can be of any type like distress in the application functionality, policy analysis, security motives, etc., which can be hosted and accessed either internally or externally. ‘Traditional’ on-premise landscape environments typically consists of 1. The systems will be subject to all the compliance regulations to which each of the member organizations is subject. You will want to have some agreement as to who will perform what activities. In particular, the creation of digital content is the outcome of a collaborative process that includes movement of large data, massive compute-intensive rendering tasks, and complex workflow executions. These clouds could be multi-tenanted. Figure 1. This means that different organizations such as government bodies, private enterprises, research organizations, and even public virtual infrastructure providers contribute with their resources to build the cloud infrastructure. Hadoop, Data Science, Statistics & others. This model also provides more controllability over the shared infrastructure resources. The location for the underlying data center could be most anywhere in the world (often referred to as location independence). The restriction is to a “community.” The restriction could be based on an industry segment, by general interest, or by whatever way a group might be defined. Heads up to v7.4! Legal issues may also arise. The cloud offers different user experiences depending on which deployment model you choose. Here we discuss an introduction to Community Cloud, architecture, advantages, disadvantages with uses, and application. Community clouds present a special set of circumstances when it comes to security because there will be multiple organizations accessing and controlling the environment. However, a community cloud still needs to enforce strong security and privacy policies. Hybrid cloud: A hybrid cloud is a combination of a public and private cloud. There is absolutely nothing wrong with that. An interesting scenario comes up when a U.S. organization uses cloud services that store their data in Europe. Community (cooperative) cloud: A community cloud is similar to extranets, but with virtualization and on-demand capabilities. One model does not fit all business types. Unlike the private model, the hybrid model builds a relatively small private datacenter for sensitive and important tasks and information, and uses the public cloud for other jobs. Thu, 07 Jul 2016 09:30:00 GMT (UTC) If the application is built on the cloud, with the help of the development platforms that support cloud processing, the quality of the application will be exceptional, in comparison to other methods. If data falls under the need for PCI or other regulatory requirements, then it could still be processed in a public cloud, but the cloud provider would need to be compliant with the regulatory requirements…It is most likely that as time progresses, more cloud providers will architect for higher security and will invest in the compliance testing necessary to support managing and processing data for customers whose regulatory compliance needs could not formerly be met by the public cloud model. While data center architecture is evolving to be more supportive of cloud applications and virtualization (see Section 15.4), a private cloud will have particular emphasis on self-service, pooling of resources, multitenancy, and metering [17]. This is due to the economies of scale, as well as the high level of automation and optimization in public cloud. Consumers need not worry about creating the cloud infrastructure. Science clouds are an interesting example of community clouds. Rajkumar Buyya, ... S. Thamarai Selvi, in Mastering Cloud Computing, 2013. The data center for private clouds is managed by the organization. One for the application / database. Some examples include invoice approval, infrastructure planning, and public hearings. Instead, they can request the services and resources on-demand and pay just for what they use. The CSU will have more control over the resources as the stack gets lower. The naturally hybrid deployment model of community clouds can easily support the storing of patient-related data in a private cloud while using the shared infrastructure for noncritical services and automating processes within hospitals. Graceful failures. The access control for the community cloud-based applications is provided in groups or individuals depending on the organizations’ policies and needs, but has similar reasons.

Apply on company website Save. One of the key differences between cloud and “traditional” (or in-house) infrastructure is the scope of user control as the roles and responsibility over cloud resources are segregated between the CSP and CSU (Pearson, 2013; Jansen and Grance, 2011). It has a higher dependency on the infrastructure involved in the architecture. Community Cloud. The infrastructure and platform services are provided to the public based on the service level agreement between the provider and the consumer. Community Cloud is used for sharing information amongst other users in the common cloud. A Feasible Community Cloud Architecture for Provisioning Infrastructure as a Service in the Government Sector @inproceedings{Castro2019AFC, title={A Feasible Community Cloud Architecture for Provisioning Infrastructure as a Service in the Government Sector}, author={Klayton Rodrigues de Castro}, … The community cloud is supposed to have a smaller carbon footprint because it harnesses underutilized resources. © 2020 - EDUCBA. According to Jon Moore’s blog, a private datacenter should have on average 10,000 servers to get an economically feasible marginal cost that is comparable to what current public cloud providers charge [14]. That could be seen as a hybrid cloud or it could be simply using two types of clouds. of public cloud is lower than the other models. From an architectural point of view, a community cloud is most likely implemented over multiple administrative domains. It mainly comes down to trust. Embed. IaaS Responsibilities by Cloud Deployment Model, Douglas K. Barry, David Dick, in Web Services, Service-Oriented Architectures, and Cloud Computing (Second Edition), 2013. Community cloud Hybrid cloud Private cloud Cloud Models Architecture and Risk from ITC 561 at Charles Sturt University These levels are hierarchical in terms of entailing increasing levels of security and additional handling requirements. The goals are to alleviate deficiencies in the individual IT infrastructures, reduce the cost of administration, and lower the cost per unit [9]. This makes great sense since there are multiple benefits to both the individual entities as well as collectively. The range of scope and control over the stack of resources is represented by the arrows. This is the second chapter of Cloud Computing Deployment Model, after Private Cloud. For this reason, you don’t want to store any data that is restricted to only your organization. The lowest stack or system infrastructure, Cloud Resources, consists of hundreds to thousands of nodes to form a datacentre. IBM IT Architect Assistant Community Edition is a collaborative tool for creating and documenting IT solution architectures. The control over resources determines the scope of the capability of the entity (CSU or CSP) to implement and manage security mechanisms. Various types of data bring with them the need for higher security concern, regulatory handling requirements, and even national security level processing requirements (you know who you are). Once the fully-functional working product is created from the development platform, it is delivered to the individual cloud units. Most media productions involve an extended ecosystem of partners. Some of the cloud security myths assume that all clouds are created equally [17], while others assume that public and private cloud providers have the same experience and capabilities to implement security measures [18] for data protection, identity management, compliance, access control rules, and other security capabilities. Responsibilities vary greatly depending on which cloud model you intend to go with. A community cloud is formed by harnessing the underutilized resources of user machines [45] and providing an infrastructure in which each can be at the same time a consumer, a producer, or a coordinator of the services offered by the cloud. This is the weak point of the chain: since virtualization allows capturing almost transparently the memory pages of an instance, these data could easily be obtained by a malicious provider. You can choose from among public, private, community, and hybrid. When migrating applications to the cloud, Enterprise Architecture has become essential for determining the best migration strategy. This extends the capacity of the private resources [18]. As a result, this model is more trusted than the public cloud, and less expensive on participating members than having a private cloud. Table 5.2. Architects play a critical role in identifying the right technologies to ensure agility, security, and competitive differentiation in this new IT frontier. Cloud deployment models differ based on the infrastructure’s owner, location, or operators and their policies. Table 5.3. This allows public cloud providers to enjoy favorable prices for IT equipment and needed resources, since they purchase them in bulk. Table 1 also shows that the operating cost (i.e., power consumption, man power expenses, rent, maintenance, upgrades, etc.) Charly (with Susannah’s help!) There is some debate on how a private cloud differs from a traditional enterprise. The model type community cloud shares the cloud infrastructure across several organizations to support specific community having common concerns. (2013) explained that the underlying cloud computing infrastructure consists of several cloud stacks (see Figure 1). Any change requests or upgrades can be implemented slowly, as it is important to maintain the cloud’s stability. This is an alternative vision of a community cloud, focusing more on the social aspect of the clouds that are formed as an aggregation of resources of community members. Users are vetted before they can obtain a clearance to access data at a given classification level, and then access is generally granted on a need-to-know basis. Both primary tiers hosted on-premise 3. Community Cloud is a kind of cloud computing method that can be set it up in the cloud, for sharing the information with different users inside a community or an organization. Different kinds of community clouds are being considered in the United States and the European Union by governments at the national and local levels.

S. Thamarai Selvi, in, Integrating digital forensic practices in cloud incident handling, Nurul Hidayah Ab Rahman, Kim-Kwang Raymond Choo, in. This month, the community voted to study Community Cloud – with particular focus on the building blocks involved. Virtualization technology is deployed in the core middleware to create the distributed infrastructure, and the Cloud Hosting Platform supports main functions of infrastructure management such as usage metering, billing, and accounting. Community More ... developing custom solutions with minimal expertise is incredibly powerful, if you do have a background in IT, software architecture, data, or cyber security, ... you can determine which systems and data you would like to stay on premises versus moving them to the cloud. E.g. Community cloud: A cloud data center shared by several organizations in a community with common concerns. You can build diagrams that are consistent with the icons and backgrounds in reference architectures and solutions in the IBM Cloud Architecture Center and customize them for a specific project or initiative. In Figure 1, we adopted the cloud stack architecture from Buyya et al. Within such a network, it is possible to have systems such as database managements systems, business information (BI)/analytics systems, application servers, and so on. However, this option is expensive in terms of resources, and the manpower needed to manage the resources. If these assumptions are true, then public cloud is the least secure, while private cloud is the most secure. Most of these threats are equally applicable to both public and private models. Finally, the community cloud model shares the cost of building the required datacenter with the cooperatives. The shared responsibility of security control implementation and management needs to be taken into consideration in planning cloud incident handling strategies. E.g. Industry and the USG need to develop frameworks to support 250 seamless implementation of federated community cloud environments. Private cloud: A private cloud or internal cloud is a datacenter owned by a cloud application provider, in which the infrastructure and platform are operated entirely by the application provider on premises. Quando: Thu, 07 Jul 2016 09:30:00 GMT. You will be able to control the application, the network, and, in most cases, the client systems. Right click or Alt+Enter to download this episode. The presenc… The community can be created between a professional community (i.e., organizations with business relationship), a geographic community, or some other well-defined community group. Below are the components involved in implementing a community cloud for any organization. Typically, a virtual private cloud provider allows the definition of a network similar to a traditional network. Continuity of operations can also be enhanced at a lower overall cost to all parties when multiple data centers are used to implement such a community cloud. A community cloud can constitute the optimal venue to provide a distributed environment in which to create a communication platform for performing such operations. Knowing what you have and having a formal structure for it is a great advantage when planning for how to protect it. Download. In the healthcare industry, there are different scenarios in which community clouds could be of use. Below are the different applications and fields where the Community Cloud is being used by the organizations. In our latest podcast, we speak to Martin Hosken and John Marrone – who both have huge experience in writing reference architectures – about how these blueprints can help with multi-cloud … In this case, the common interest driving different organizations sharing a large distributed infrastructure is scientific computing. Scientific research. THE CERTIFICATION NAMES ARE THE TRADEMARKS OF THEIR RESPECTIVE OWNERS. Table 5.1. Cloud systems take a lot to maintain, in terms of technical efforts and cost as well. mission, security requirements, and policy). Community clouds are also different from private clouds, where the services are generally delivered within the institution that owns the cloud. However, it also tends toward overclassifying information based on the consequences of data exposure. It may be managed by the organizations or a third party and may exist on premise or off premise. The type of cloud may vary in accordance to the needs of the organization. The problem is not as evident as it seems: even though cryptography can help secure the transit of data from the private premises to the cloud infrastructure, in order to be processed the information needs to be decrypted in memory. On the other hand, public providers tend to invest more in automation and optimization, which results in fewer administrative staff. SAP BW 1.2. Table 5.3 outlines IaaS provider responsibilities. Many organizations would rather trust a third party than trust themselves. Hybrid architectures allow for a staged migration where cloud-based cost savings and efficiency are immediately realized for apps and data that are ready to move now, while essential mainframe resources can be moved later. European countries are more restrictive and protect the right of privacy. In the commercial world, different categories generally apply, but these tend not to be hierarchical. Cloud computing is not an exception. You could be setting yourself up for a big headache if you do. Security. Professional Cloud Architect — A Professional Cloud Architect enables organizations to leverage Google Cloud technologies. 249 community cloud environments”. The selection of a cloud deployment model depends on the consumers’ needs and budget, and on whether they favor price reduction and control delegation over flexibility, control, and customization. Save this job with your existing LinkedIn profile, or create a new one. Only Open Source guarantees interoperability, transparency and independence from legal claims of … Production costs drop significantly as the number of units produced increase1[13]. In a community cloud, member organizations will have shared access to all the application and system audit logs. Internally, it becomes a complex system to manage. In a community cloud environment, your control over the user experience depends on the agreement you have in place with the other members of the community. These components typically consist of a front end platform (fat client, thin client, mobile),back end platforms (servers, storage), a cloud based delivery, and a network (Internet, Intranet, Intercloud). Public cloud: A cloud data center owned by an organization selling cloud services to the general public. We use cookies to help provide and enhance our service and tailor content and ads. However, the lack of a trust model between the cloud providers and consumers is the main obstacle for this model. Typically, a public cloud provider allows multiple organizations to provide multiple types of services (often referred to as multi-tenancy). SAP BusinessObjects BI Suite 2. In fact, one of the big drivers of public clouds is organizations’ desire to reduce their internal responsibilities. Schedule a demo See first-hand how the unrivalled power of our analytics database can help you access data from anywhere in your organization. For this reason, the initial cost can vary; the larger the community the smaller the share and the lower the cost. Community cloud architecture to improve use accessibility with security compliance in health big data applications @inproceedings{Valluripally2019CommunityCA, title={Community cloud architecture to improve use accessibility with security compliance in health big data applications}, author={Samaikya Valluripally … If you choose to go with a private cloud, you will complete control over the user experience. A cloud computing system must make a copy of all its clients' information and store it on other devices. The Development Platform aids in manipulating the non –standard properties of the community cloud, and few such platforms are Salesforce, SAP, and any organization-specific platforms. For this reason, the cost of adopting the hybrid cloud model is between that of public and private clouds. By the deployment environment, we mean the physical location, the infrastructure facilities, the platform constraints, as well as anything that can affect the access mechanisms of the deployed applications. Hybrid clouds have the advantage that jobs can be allocated on either a private cloud or a public cloud on a pay per use basis. In PaaS, for example, the CSU is responsible for their application security protection (e.g., secure coding, and encryption) while the CSP is responsible for hypervisor protection (e.g., hypervisor vulnerability management). For example, the CSU will have less control over the resources in SaaS but more control in IaaS; and conversely the CSP will have more control in SaaS but less control in IaaS. They involve business-to-administration, citizen-to-administration, and possibly business-to-business processes. Hybrid cloud: This is the combination of any of the above. The underlying data center might be provided by a third party or by one member of the community. Private cloud: A private cloud is restricted to one organization. A community cloud is a cloud service model that provides a cloud computing solution to a limited number of individuals or organizations that is governed, managed and secured commonly by all the participating organizations or a third party managed service provider. This condition poses challenges for confidential data, which organizations cannot afford to reveal. This eliminates the need for a trust model and provides more flexibility. Mohammad Hamdaqa, Ladan Tahvildari, in Advances in Computers, 2012. The applications built under the cloud are typically responsive, in the sense, the interface can be adapted to any form and shape of the devices. “We’ve enjoyed a true transformation with our move to the cloud, embodied by our widespread use of what we call Commercial Cloud Services, or C2S,” Sherman said. In this Public Cloud Tutorial, we are going to learn architecture, advantages, and structure. The scope of control between CSP and CSU on cloud computing architecture. This can manage either by the third party or internally. Salesforce Community Cloud Technical Architect Accenture in India Pune, Maharashtra, India 2 hours ago Be among the first 25 applicants. In this model, cloud infrastructure is provided on the premises or at the data center owned by third party. The term community cloud can also identify a more specific type of cloud that arises from concern over the controls of vendors in cloud computing and that aspire to combine the principles of digital ecosystems7 [44] with the case study of cloud computing. Cloud applications can be habituated and altered whenever required, as the users’ need can be changing from time to time. The system is reliable in terms of security and long-lasting. The public cloud can also be described as an external cloud when viewed from within a given organization. To begin, one can identify categories of information that can be processed with lesser security concern and fewer controls than other kinds of data. See who Accenture in India has hired for this role. For instance, when multiple government agencies that transact business with each other have their processing colocated in a single facility, they can achieve both savings and increased security in terms of reducing the amount of traffic that would otherwise need to traverse the Internet. It is a cloud which is based on Cloud Computing. In this case, should this organization be suspected by the government, it would become difficult or even impossible for the U.S. government to take control of the data stored in a cloud datacenter located in Europe. This means that different organizations such as government bodies, private enterprises, research organizations, and even public virtual infrastructure providers contribute with their resources to build the cloud infrastructure. It provides a one –spot place for user’s various activities, which can be enabled in the form of single sign –on ability. The deployment models are as follows [4]: Private cloud: A cloud operated solely for one organization. In user-level middleware, cloud service is offered as a development platform, referred to PaaS, and CSU develops applications to run on the core middleware infrastructure. So, your organization may be subject to regulations with which you have little familiarity. Community Cloud can be defined as the multiparty communication enterprise where the contents are pooled amongst various associations in a cloud space and that falls under a common community. By removing the dependency on cloud vendors, community clouds are open systems in which fair competition between different solutions can happen. The community cloud is comparatively more secure than the public cloud but less secured than the private cloud. We can broadly divide the cloud architecture into two parts: Front End; Back End; Each of the ends is connected through a network, usually Internet. Community Cloud provides contents be available for the users, in accordance with the access privilege, at any time and any place. The following tables outline who is responsible for what in each environment configuration. U.S. legislation is known to give extreme powers to government agencies to acquire confidential data when there is the suspicion of operations leading to a threat to national security. Issues. Public cloud is the least expensive choice for application hosting. Convenience and control. Security is always a complicated topic. Fogwing Community Cloud Architecture Model Please note the Fogwing Enterprise Cloud has much large components, data processing, analytics and intelligence capabilities. Community cloud is based on the trust relation between all the members, which is driven by their mutual benefits [10,11]. The cloud service shares among various organizations and companies which belong to the same community with the common concerns. Cloud involves mélange of designs and patterns – some existing and some new. The level of controllability and flexibility can also affect the level of trust. Table 1.

That's because these devices, like all computers, occasionally break down. Within a community cloud there is no conflict between convenience and control because the cloud is shared and owned by the community, which makes all the decisions through a collective democratic process. It helps in maintaining the solitude of the organization’s contents in the cloud. Being based on a collective that provides resources and services, the infrastructure turns out to be more scalable because the system can grow simply by expanding its user base. This type of infrastructure resource sharing between multiple organizations or consumers, is referred to as the multi-tenancy model. This is a guide to Community Cloud. Besides the practical aspects, which are related to configuration, networking, and sizing of cloud computing systems, a new set of challenges concerning the dynamic provisioning of cloud computing services and resources arises. Public sector. Whom do you trust with your security? The intelligence community’s two flagship cloud programs are C2S and IC-GovCloud. Most often that organization is the single tenant—that is, unless the organization might want to host a private, multi-tenanted cloud for various internal segments or units of the organization. Cloud Computing architecture comprises of many cloud components, which are loosely coupled. Energy and other core industries. PaaS Responsibilities by Cloud Deployment Model. In a community cloud, all the participants in the community may have access to the data. A Cloud Computing deployment model is a model that describes the environment where cloud applications and services can be installed, in order to be available to consumers. Hybrid cloud: A cloud infrastructure made from two or more types of clouds, such as private, public, or community, that are bound together by standardized or proprietary technology that enables data and application portability. Virtual private cloud: C. R.’s organization wanted to get out of the business of maintaining an enterprise data warehouse in its data center and decided to use a virtual private cloud. Sovereign Cloud Stack. However, the Cloud Computing paradigm introduces new security threats that did not exist in traditional datacenters, such as threats related to sharing resources through virtualization [16]. Buyya et al. The National Institute of Standards and Technologies (NIST) [43] characterizes community clouds as follows: The infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). The infrastructure here is a common entity that is frequently used by the organizations in the cloud, in order to provide necessary sustenance for the smooth functioning of the cloud system. Cloud systems come with the ability to expand when and as required, which can be seen as scalability of the system. Register to attend this complimentary webinar.
