community cloud architecture

Professional Cloud Architect — A Professional Cloud Architect enables organizations to leverage Google Cloud technologies. Charly (with Susannah’s help!) For this reason, the cost of adopting the hybrid cloud model is between that of public and private clouds. There is absolutely nothing wrong with that. Reference architectures provide a solid blueprint for organizations seeking a proven path to cloud. 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. This webinar features a conversation about key patterns, including detecting failures, and recovering quickly and efficiently, necessary to maintain resiliency. 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. Public cloud: The email, calendar, photo, and music services used in the AV system analogy are all in the public cloud. Security is such an important concern that you need to go with what you trust. Thu, 07 Jul 2016 09:30:00 GMT (UTC) Architecting for a cloud and mobile-first world More than ever, enterprises are relying on architects to help them embrace digital transformation. 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. This can also be called an internal cloud. Convenience and control. 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). You can choose from among public, private, community, and hybrid. The benefits of these community clouds are the following: Openness. The users of a specific community cloud fall into a well-identified community, sharing the same concerns or needs; they can be government bodies, industries, or even simple users, but all of them focus on the same issues for their interaction with the cloud. Community clouds are also different from private clouds, where the services are generally delivered within the institution that owns the cloud. This eliminates the need for a trust model and provides more flexibility. The following diagram shows the graphical view of cloud computing architecture: Front End This allows you to tune everything for best performance and usability. Below are the components involved in implementing a community cloud for any organization. Additional subcategories of classification can be as sedimented within a classification level and entail the need to maintain separation even from users who are cleared at the same, say Top Secret level but who have not been read into the category in question. In a community cloud, all the participants in the community may have access to the data. In this model, cloud infrastructure is provided on the premises or at the data center owned by third party. 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. In a community cloud, member organizations will have shared access to all the application and system audit logs. 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]. “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. 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. Community clouds present a special set of circumstances when it comes to security because there will be multiple organizations accessing and controlling the environment. The intelligence community’s two flagship cloud programs are C2S and IC-GovCloud. The following tables outline who is responsible for what in each environment configuration. Environmental sustainability. It helps in maintaining the solitude of the organization’s contents in the cloud. The deployment models are as follows [4]: Private cloud: A cloud operated solely for one organization. However, it also tends toward overclassifying information based on the consequences of data exposure. 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. The type of cloud may vary in accordance to the needs of the organization. Community cloud is based on the trust relation between all the members, which is driven by their mutual benefits [10,11]. For this reason, the initial cost can vary; the larger the community the smaller the share and the lower the cost. In this, the service provider makes resources which can be virtual machines, application or storage for the public by the means of internet. The first-time implementation costs way higher than any other normal application. Once the fully-functional working product is created from the development platform, it is delivered to the individual cloud units. Cloud Architecture, Community, Communities. 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. They involve business-to-administration, citizen-to-administration, and possibly business-to-business processes. 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. 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. In the healthcare industry, there are different scenarios in which community clouds could be of use. And so, it can be accessed from a computer system or a tablet or even a mobile interface. Many organizations would rather trust a third party than trust themselves. When dealing with any large system a common problem is how to evolve its architecture over time. Figure 4.6 provides a general view of the usage scenario of community clouds, together with reference architecture. 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. We use cookies to help provide and enhance our service and tailor content and ads. Community cloud: A cloud data center shared by several organizations in a community with common concerns. The CSU will have more control over the resources as the stack gets lower. In this Public Cloud Tutorial, we are going to learn architecture, advantages, and structure. © 2020 - EDUCBA. However, a community cloud still needs to enforce strong security and privacy policies. 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. Cloud Architect Industry insights for the Cloud Architect Stay in the know about the latest Cloud services, products and practices to keep your enterprise on the edge of innovation. Scientific research. When migrating applications to the cloud, Enterprise Architecture has become essential for determining the best migration strategy.

A Comparison Between the Different Cloud Deployment Models. 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. Read more Study Group XII: Community … Moreover, governmental processes involve several institutions and agencies and are aimed at providing strategic solutions at local, national, and international administrative levels. Nearly all of the services used by the VPA in the story about C. R.’s trip are also in the public cloud. Acquired through Amazon, C2S is a CIA managed cloud hosting top secret data. 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. Security. However, it is important to note that the level of trust is not related to the actual security level. Community (cooperative) cloud: A community cloud is similar to extranets, but with virtualization and on-demand capabilities. As any new technology develops and becomes popular, new issues have to be faced. 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. 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. In fact, one of the big drivers of public clouds is organizations’ desire to reduce their internal responsibilities. These clouds could be multi-tenanted.

S. Thamarai Selvi, in, Integrating digital forensic practices in cloud incident handling, Nurul Hidayah Ab Rahman, Kim-Kwang Raymond Choo, in. Security is always a complicated topic. Register to attend this complimentary webinar. 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. See who Accenture in India has hired for this role. This is a guide to Community Cloud. Community. 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. You can also go through our other related articles to learn more –, Cloud Computing Training (18 Courses, 5+ Projects). In a community cloud, compliance can be particularly tricky. In reality, this is a somewhat ambiguous term since an organization might have a private cloud and use the public cloud. If you want to learn more about Enterprise Cloud Architecture, please reach out our sales team here . 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. There are four main Cloud Computing deployment models: public, private, hybrid, and community cloud: Public cloud: A public cloud or external cloud is an open model, in which the infrastructure facilities are provided by a third party (the cloud providers). The cloud offers different user experiences depending on which deployment model you choose. However, this option is expensive in terms of resources, and the manpower needed to manage the resources. Most media productions involve an extended ecosystem of partners. By continuing you agree to the use of cookies. Organizations do not own the infrastructure they use to process data and store information. You will be able to control the application, the network, and, in most cases, the client systems. A virtual private cloud involves some type of partitioning to ensure that the private cloud remains private. It lets the users to communicate and collaborate with other users/ team members that are operating under one cloud. Right click or Alt+Enter to download this episode. 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. 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. Public sector. Explore the architecture and dive into the inner workings of our analytics database. IaaS Responsibilities by Cloud Deployment Model, Douglas K. Barry, David Dick, in Web Services, Service-Oriented Architectures, and Cloud Computing (Second Edition), 2013. From Wikipedia, the free encyclopedia Cloud computing architecture refers to the components and subcomponents required for cloud computing. 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. Sovereign Cloud Stack (SCS) is cloud technology built entirely with Open Source Software -- as an alternative to propietary cloud technology. E.g. 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. 249 community cloud environments”. This model has tremendous potential for entities or companies that are subject to identical regulatory, compliance, or legal restrictions. Community Clouds can be classified as a Distributed Architecture, where each unit is formed by incorporating the other services from similar or different clouds under the same domain, so as to fulfill the precise requirements provided by the clients, their communities, and related segments of the client. Any change requests or upgrades can be implemented slowly, as it is important to maintain the cloud’s stability. IBM IT Architect Assistant Community Edition is a collaborative tool for creating and documenting IT solution architectures. One model does not fit all business types. 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). 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. Responsibilities vary greatly depending on which cloud model you intend to go with. This website or its third-party tools use cookies, which are necessary to its functioning and required to achieve the purposes illustrated in the cookie policy. Cloud computing systems need at least twice the number of storage devices it requires to keep all its clients' information stored. Carolyn J. Sher DeCusatis, Aparicio Carranza, in Handbook of Fiber Optic Data Communication (Fourth Edition), 2013. This allows public cloud providers to enjoy favorable prices for IT equipment and needed resources, since they purchase them in bulk. Healthcare industry. The infrastructure and platform services are provided to the public based on the service level agreement between the provider and the consumer. The control over resources determines the scope of the capability of the entity (CSU or CSP) to implement and manage security mechanisms. This can be another key factor in your decision. 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. Table 5.1. If you go with a public cloud, in some cases you might have no control over the user experience. of public cloud is lower than the other models. Graceful failures. 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. Production costs drop significantly as the number of units produced increase1[13]. 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. 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]. 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. This condition poses challenges for confidential data, which organizations cannot afford to reveal. Apply on company website Save. Meetups Join thousands of developers, DevOps, IT pros, and architects at community meetups where we share knowledge, best practices, and insights on using Google Cloud and other Google developer products and platforms. By removing the dependency on cloud vendors, community clouds are open systems in which fair competition between different solutions can happen. This type of infrastructure resource sharing between multiple organizations or consumers, is referred to as the multi-tenancy model. 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. European countries are more restrictive and protect the right of privacy. 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. If you choose to go with a private cloud, you will complete control over the user experience. IaaS is formed from the underlying system infrastructure and core middleware. SaaS Responsibilities by Cloud Deployment Model. Public cloud providers tend to implement best practices and try to ensure security at every level of the security stack. 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. 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. On the other hand, while community cloud consumers can have access and control over the infrastructure, this controllability is bounded by the community policies and agreements. E.g.
