community cloud architecture

With a thorough understanding of cloud architecture and Google Cloud Platform , this individual can design, develop, and manage robust, secure, scalable, highly available, and dynamic solutions to drive business objectives. Sovereign Cloud Stack (SCS) is cloud technology built entirely with Open Source Software -- as an alternative to propietary cloud technology. 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 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. 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. 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 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. DOI: 10.1145/3325112.3325229 Corpus ID: 190230577. Nearly all of the services used by the VPA in the story about C. R.’s trip are also in the public cloud.

S. Thamarai Selvi, in, Integrating digital forensic practices in cloud incident handling, Nurul Hidayah Ab Rahman, Kim-Kwang Raymond Choo, in. And so, it can be accessed from a computer system or a tablet or even a mobile interface. The presenc… The range of scope and control over the stack of resources is represented by the arrows. 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. 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. The location for the underlying data center could be most anywhere in the world (often referred to as location independence). Security in terms of confidentiality, secrecy, and protection of data in a cloud environment is another important challenge. You can choose from among public, private, community, and hybrid. Your can now test the 7.4.1 M3. 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. They involve business-to-administration, citizen-to-administration, and possibly business-to-business processes. In Figure 1, we adopted the cloud stack architecture from Buyya et al. For this reason, the cost of adopting the hybrid cloud model is between that of public and private clouds. Cloud computing is not an exception. We use cookies to help provide and enhance our service and tailor content and ads. Public cloud is the least expensive choice for application hosting. 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. It depends on the organization’s motive and method for handling their data. The underlying data center might be provided by a third party or by one member of the community. Some examples include invoice approval, infrastructure planning, and public hearings. 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. When migrating applications to the cloud, Enterprise Architecture has become essential for determining the best migration strategy. Register to attend this complimentary webinar. Community cloud Hybrid cloud Private cloud Cloud Models Architecture and Risk from ITC 561 at Charles Sturt University One for the Business Intelligence or Planning system. Science clouds are an interesting example of community clouds. 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. Professional Cloud Architect — A Professional Cloud Architect enables organizations to leverage Google Cloud technologies. © 2020 - EDUCBA. 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 goals are to alleviate deficiencies in the individual IT infrastructures, reduce the cost of administration, and lower the cost per unit [9]. 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 model also provides more controllability over the shared infrastructure resources. Furthermore, regulatory compliance is a main obstacle facing community cloud adoption. Community Cloud Architecture. Most media productions involve an extended ecosystem of partners. Legal issues may also arise. Consumers need not worry about creating the cloud infrastructure. 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. To begin, one can identify categories of information that can be processed with lesser security concern and fewer controls than other kinds of data. Organizations can implement their own policies with regards to privacy, security, and access mechanisms. 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. Moreover, governmental processes involve several institutions and agencies and are aimed at providing strategic solutions at local, national, and international administrative levels. However, the lack of a trust model between the cloud providers and consumers is the main obstacle for this model. In this, the service provider makes resources which can be virtual machines, application or storage for the public by the means of internet. 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). E.g. The lowest stack or system infrastructure, Cloud Resources, consists of hundreds to thousands of nodes to form a datacentre. (2013) and the scope of control from Jansen and Grance (2011) to explain the control scope between the CSP and CSU, for each stack of the cloud architecture. A Comparison Between the Different Cloud Deployment Models. Community to share and get the latest about Microsoft Learn . Typically, a virtual private cloud provider allows the definition of a network similar to a traditional network. Issues. Cloud systems come with the ability to expand when and as required, which can be seen as scalability of the system. Legal and political restrictions in the public sector can limit the adoption of public cloud offerings. 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. Table 5.3 outlines IaaS provider responsibilities. These levels are hierarchical in terms of entailing increasing levels of security and additional handling requirements. After you have chosen the cloud service model that best fits your need, you need to determine your cloud deployment model. 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. Conversely, a private cloud requires a big initial capital investment in order to build the private datacenter [12]. This is a guide to Community Cloud. Table 5.3. Charly (with Susannah’s help!) In this Public Cloud Tutorial, we are going to learn architecture, advantages, and structure. Most of these threats are equally applicable to both public and private models. This allows public cloud providers to enjoy favorable prices for IT equipment and needed resources, since they purchase them in bulk. Cloud Architecture Patterns. 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. Community cloud: A cloud data center shared by several organizations in a community with common concerns. However, it is important to note that the level of trust is not related to the actual security level. This benefits the user of community cloud to know and analyze the business demand first. of public cloud is lower than the other models. Dear Community, We are pleased to announce that the Milestone 4 of Talend Open Studio v7.4.1 is now publicly available, for testing only.This milestone primarily contains bug fixes, and is recommended for experienced users who would like to get an early preview of upcoming 7.4 release. Trolling though logs can be particularly tedious and time consuming, so you don’t want people wasting time doing duplicate work. The benefits of these community clouds are the following: Openness. 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. However, having both public and private clouds working together requires interoperability and portability of both applications and data to allow communication between the models. “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 these sectors, community clouds can bundle the comprehensive set of solutions that together vertically address management, deployment, and orchestration of services and operations. In the media industry, companies are looking for low-cost, agile, and simple solutions to improve the efficiency of content production. This month, the community voted to study Community Cloud – with particular focus on the building blocks involved. 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. Knowing what you have and having a formal structure for it is a great advantage when planning for how to protect it. 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. New, interesting problems and challenges are regularly being posed to the cloud community, including IT practitioners, managers, governments, and regulators. 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. Application services are the middleware services based out of the production systems designed and functioning specific to the application’s motives. 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). 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 … Whom do you trust with your security? You will be able to control the application, the network, and, in most cases, the client systems. In a sense, the solution is more of a community cloud than a public cloud. Schedule a demo See first-hand how the unrivalled power of our analytics database can help you access data from anywhere in your organization. This allows you to tune everything for best performance and usability. 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. By removing the dependency on cloud vendors, community clouds are open systems in which fair competition between different solutions can happen. 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. The national security information classification scheme is very mature and quite effective in managing control over and access to classified information. Each environment (Sandbox, Dev… For this reason, you don’t want to store any data that is restricted to only your organization.

Save this job with your existing LinkedIn profile, or create a new one. Community cloud provides an infrastructure to share cloud resources and capabilities among several organizations. It may be managed by the organizations or a third party and may exist on premise or off premise. Cloud systems take a lot to maintain, in terms of technical efforts and cost as well. The infrastructure and platform services are provided to the public based on the service level agreement between the provider and the consumer. In this case, the common interest driving different organizations sharing a large distributed infrastructure is scientific computing. Many organizations would rather trust a third party than trust themselves. Convenience and control. 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. Healthcare industry. It lets the users to communicate and collaborate with other users/ team members that are operating under one cloud. 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. Buyya et al. The scope of control between CSP and CSU on cloud computing architecture. It mainly comes down to trust. This makes great sense since there are multiple benefits to both the individual entities as well as collectively. That could be seen as a hybrid cloud or it could be simply using two types of clouds. An interesting scenario comes up when a U.S. organization uses cloud services that store their data in Europe. There are several different ways cloud computing is made available for use. The cloud service shares among various organizations and companies which belong to the same community with the common concerns. In a community cloud, member organizations will have shared access to all the application and system audit logs. Since there is no single provider or vendor in control of the infrastructure, there is no single point of failure. A cloud computing system must make a copy of all its clients' information and store it on other devices. 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. This condition poses challenges for confidential data, which organizations cannot afford to reveal. Salesforce Community Cloud Technical Architect Accenture in India Pune, Maharashtra, India 2 hours ago Be among the first 25 applicants. There is some debate on how a private cloud differs from a traditional enterprise. 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. The Private cloud reference architecture provides developers with an optimal platform for provisioning, building, and deploying applications and their components in a self-service fashion. It’s even more complicated when you’re dealing with the cloud. Architects play a critical role in identifying the right technologies to ensure agility, security, and competitive differentiation in this new IT frontier. ALL RIGHTS RESERVED. The model type community cloud shares the cloud infrastructure across several organizations to support specific community having common concerns. The following diagram shows the graphical view of cloud computing architecture: Front End The first-time implementation costs way higher than any other normal application. That sort of information classification would lend itself to a public cloud, to hybrid cloud processing, or to a community cloud. Thu, 07 Jul 2016 09:30:00 GMT (UTC) Figure 1. Table 5.1. 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 can be another key factor in your decision. Cloud Architecture, Community, Communities. Scientific research. The following tables outline who is responsible for what in each environment configuration. Once the fully-functional working product is created from the development platform, it is delivered to the individual cloud units. 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. From an architectural point of view, a community cloud is most likely implemented over multiple administrative domains. Table 1 also shows that the operating cost (i.e., power consumption, man power expenses, rent, maintenance, upgrades, etc.) It is usually implemented on the applications used for people management based organizations, like academic, banking, finance, social media platforms, etc. 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. If these assumptions are true, then public cloud is the least secure, while private cloud is the most secure. Vic (J.R.) Winkler, in Securing the Cloud, 2011. One model does not fit all business types. Figure 4.6 provides a general view of the usage scenario of community clouds, together with reference architecture. Carolyn J. Sher DeCusatis, Aparicio Carranza, in Handbook of Fiber Optic Data Communication (Fourth Edition), 2013. Most people believe that the hybrid cloud model is the model that will be used in most organizations. Sovereign Cloud Stack. 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. Cloud Architecture for Resiliency Resiliency is the ability of a system to gracefully handle and recover from failures. In a community cloud, all the participants in the community may have access to the data. If you choose to go with a private cloud, you will complete control over the user experience. Embed. Security is always a complicated topic. This type of cloud computingis best compatible with ventures, business organizations, research organizations, and tenders. You could be setting yourself up for a big headache if you do. Below are the several areas where the Community Cloud is used on a daily basis. Security. 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. 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). Hybrid cloud: This is the combination of any of the above. This can also be called an internal cloud. Indian Banking Community Cloud 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. This model has tremendous potential for entities or companies that are subject to identical regulatory, compliance, or legal restrictions. SAP BW 1.2. You can also go through our other related articles to learn more –, Cloud Computing Training (18 Courses, 5+ Projects). In the healthcare industry, there are different scenarios in which community clouds could be of use. However, you still must consider which model is best for your organization. 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. Derrick Rountree, Ileana Castrillo, in The Basics of Cloud Computing, 2014. The community cloud is supposed to have a smaller carbon footprint because it harnesses underutilized resources. This initiative by the Institute for Development and Research in Banking Technology in Hyderabad, India provides cloud … A virtual private cloud involves some type of partitioning to ensure that the private cloud remains private. 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. 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. 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). takes us through the various elements involved in building a Salesforce community! We apply technologies to address a problem; ... with big data and with the challenges you might encounter on your journey to the cloud. When dealing with any large system a common problem is how to evolve its architecture over time. Public cloud providers tend to implement best practices and try to ensure security at every level of the security stack. Community cloud is based on the trust relation between all the members, which is driven by their mutual benefits [10,11]. 251 252 In Community Cloud deployments, infrastructure is shared by organizations that have common 253 interests (e.g. Acquired through Amazon, C2S is a CIA managed cloud hosting top secret data. The systems will be subject to all the compliance regulations to which each of the member organizations is subject. 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. Table 5.1 outlines SaaS provider responsibilities. There is absolutely nothing wrong with that. 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 … 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. Security is such an important concern that you need to go with what you trust. Below are the different applications and fields where the Community Cloud is being used by the organizations. 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. 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? The CSU will have more control over the resources as the stack gets lower. This is the second chapter of Cloud Computing Deployment Model, after Private 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. Since these industries involve different providers, vendors, and organizations, a community cloud can provide the right type of infrastructure to create an open and fair market. Below are the components involved in implementing a community cloud for any organization. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Table 5.2. 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. So, your organization may be subject to regulations with which you have little familiarity. Community Cloud provides contents be available for the users, in accordance with the access privilege, at any time and any place. It is a cloud which is based on Cloud Computing. From Wikipedia, the free encyclopedia Cloud computing architecture refers to the components and subcomponents required for cloud computing. Heads up to v7.4! Hadoop, Data Science, Statistics & others. 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. Download. 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. It provides a one –spot place for user’s various activities, which can be enabled in the form of single sign –on ability. The type of cloud may vary in accordance to the needs of the organization. European countries are more restrictive and protect the right of privacy. 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. It has a higher dependency on the infrastructure involved in the architecture. SaaS Responsibilities by Cloud Deployment Model. Cloud applications can be habituated and altered whenever required, as the users’ need can be changing from time to time. In both cases, the concept of community is fundamental. 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. In the commercial world, different categories generally apply, but these tend not to be hierarchical. The public cloud can also be described as an external cloud when viewed from within a given organization. (2013) explained that the underlying cloud computing infrastructure consists of several cloud stacks (see Figure 1). IaaS is formed from the underlying system infrastructure and core middleware. 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. 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. Environmental sustainability. Two primary tiers 1.1. IBM IT Architect Assistant Community Edition is a collaborative tool for creating and documenting IT solution architectures. Community (cooperative) cloud: A community cloud is similar to extranets, but with virtualization and on-demand capabilities. The deployment models are as follows [4]: Private cloud: A cloud operated solely for one organization. This is due to the economies of scale, as well as the high level of automation and optimization in public cloud. On the other hand, public providers tend to invest more in automation and optimization, which results in fewer administrative staff. National security information, be it Federal, military, or intelligence data will generally fall under the following hierarchical classification levels: Unclassified, Sensitive But Unclassified, Confidential, Secret, and Top Secret.
