functional requirements for cloud computing

The other 400 words involved specifications. Mapping Non-Functional Requirements to Cloud Applications David Villegas and S. Masoud Sadjadi School of Computing and Information Sciences Florida International University Miami, Florida {dvill013, sadjadi}@cs.fiu.edu Abstract—Cloud computing represents a solution for appli-cations with high scalability needs where usage patterns, and Diane, in all seriousness, this question really is way to long and complex to answer on Quora. Only Managerial level employees have the right to view revenue data. Details of operations conducted in every screen 2. Platform as a Service (PaaS) is a cloud computing model in which a specific development and deployment platform-for example, Java EE, IBM WebSphere, Oracle, Google Apps, .NET, BizTalk-is the basis for deployment. Stay up to date on trends in digital transformation, the future of application services, and insights into emerging technologies with blogs from the Office of the CTO. You can add some custom feels or customize some workflows, choose how you link things together or display things on the user interface. The control plane, on the other hand, is more concerned with managing that data in response to context and policy; it changes the "how" of the data plane. F5 integrates and partners with the world's leading technology companies. Certainly, a fairly strong argument can be made that web-hosting services from a decade ago represent the first implementations of software as a service (SaaS). IaaS leverages the dynamic control plane to enable on-demand scalability through the rapid and automatic provisioning of compute resources. The data plane is the basic connectivity that handles traffic flow to and from destinations. It is necessary to share information between the layer of compute resources and manage resources so as not to waste compute resources that could be better used by another application. This layer typically conjures the image of a traditional server. PaaS is a kind of framework computing in that the platform provided is the core framework in which applications are specifically developed. And take a technical tour of IBM® Bluemix™, the IBM PaaS cloud operating environment, to see how Bluemix supports the design and creation of reliable, highly available, and scalable applications. It provides a standard approach for boundary and application level security for impact level four and five data hosted in commercial cloud environments. It should have descriptions of system reports or other outputs 4. Oracle Sales Cloud for Outlook. For SaaS, you must establish that there are cloud services that meet your needs for application processing. A larger customer community also provides rich opportunities for collaboration between customers, creating communities that can share interests and foster best practices. This ability is essentially the run-time environment in which the applications are deployed. These applications will not run on any other platform, and often include platform-specific extensions or services, such as Amazon's SimpleDB, that cannot be ported to other environments. Requirement 1: Service and Resource Management. Despite the appearance that applications deployed in a SaaS cloud architecture are merely hosted applications-for example, the ASP model of the "dot com/dot bomb" era-these business computing-focused architectures are often built on a PaaS deployed upon an IaaS. I have seen several startups - which are using cloud services for all their computing needs. Cloud management platforms must enable fast, automated provisioning of dev platforms to support these business initiatives. Of course, today's systems are much more complicated and versatile. Order Cloud Outsourcing   Download Selected Pages. The scope of this Technical Report is to define the functional requirements and reference architecture of cloud computing, which includes the functional architecture, functional layers and blocks. Recommendation ITU-T Y.3513 introduces the concept of Infrastructure as a Service (IaaS) and describes its functional requirements. These requirements also help the development team and client to ensure they are working to reach the same goals. Right now, most of the small, medium enterprises have gone 100% on cloud. They are not easy for stakeholders to articulate but they know that the software will not be usable without some of these non-functional characteristics ( … In addition, there are different ways to view the interaction of various operations within the architecture, depending on your role. Scalability cloud … This new dynamic paradigm must be able to intercept application and data traffic, interpret the current context, and instruct the cloud infrastructure on how to most efficiently deliver the request. Recommendation ITU-T Y.3513 introduces the concept of Infrastructure as a Service (IaaS) and describes its functional requirements. Functional requirements of a system can relate to hardware, software or both in terms of calculations, technical details, data manipulation and processing or other specific functionality that defines what a system is supposed to accomplish. This almost always takes the form of a virtualized infrastructure and infrastructure services that enables the customer to deploy virtual machines as components that are managed through a console. Meeting the Network Requirements of Cloud and Virtual Computing with Local Management SYNOPSIS | The widespread adoption of virtualized computing (including as the enabling technology in Clouds ) and the various ways that enterprises will change to fully exploit it will have a profound effect on the network and on IT Network Operations Groups. The background color for all windows in the application will be blue and have a hexadecimal RGB color value of 0x0000FF. 5. Fuller, a St. Paul, Minnesota-based manufacturer with more than $1 billion in annual revenues This document outlines 10 critical requirements of cloud computing to help organizations distinguish the difference between real and fake cloud applications. This is the very foundation upon which a cloud is built and, as suggested, is made up of the components most often supplied by vendors who provide IaaS solutions to their customers. functional requirements and architecture according to the following steps and priorities. Given the dynamic and non-static mappings between the applications and the resources-regardless of whether the IT organization built the application from the ground-up to meet the needs of the business or the business simply deployed their own solutions-cloud architecture enables them to seamlessly integrate at the most appropriate point for the organization. The overall success of these initiatives depends upon well executed security requirements, defined and understood by both DoD Components and industry. Failing to define requirements may cause miscommunication between the team and client, and increase the chances of the project failing. These are the requirements for what the system should do. High availability - Equip world-class facilities with proven high-availability infrastructure and, Facilities with reliable power, cooling, and network infrastructure, High-availability infrastructure: networking, server infrastructure, and software, Metrics with detailed historical availability data on the entire service, not just on individual servers. There is no doubt that some concept of cloud computing will become the primary method of delivering business critical applications in the coming years. This was all of the functional requirements. Step 1: … Cloud computing's impact will continue to be felt for many years regardless of how it all comes together in the end. The core idea of cloud architecture is to connect users-who might be mobile and moving between LANs, WLANs, and Internet connections-and services to the applications they consume, which can also move between cloud centers based on different needs of the business. Built from core components that include compute resources and management resources, the base layer of the cloud architecture requires the most technical competence to build and deploy. Critical Requirement No. The concept of framework computing comes from architectures in which a layer of capabilities and services are provided that abstract (and insulate) developers from the underlying details. Defining cloud computing and notions of "the cloud" are extremely ambiguous and difficult to nail down. Seemingly every week, a new cloud delivery service pops up, offering something bigger and better than the one before. Status : In force (prepublished) Summary . Diane, in all seriousness, this question really is way to long and complex to answer on Quora. These requirements include scalability, adaptability, extensibility, and manageability. If Non-functional requirements when defined and executed well will help to make the system easy to use and enhance the performance. The dynamic control plane must also communicate with the infrastructure-the data plane-to change the current delivery model to meet the needs identified. Steven John April 18, 2011. You can hardly open any technology or business journal, website, or newspaper today without hearing some commentary on cloud computing-what it is and how it will change IT and business. As hardware resources and servers are spun-up or decommissioned, as applications are moved from development to production, or as entire applications are moved from the internal data center to a cloud provider, the cloud architecture requires a dynamic control plane that monitors the data and ensures that it is constantly connected in the best possible manner. At the apex of the pyramid are users accessing the applications; in the center is a dynamic control plane that traverses all others and provides real-time connectivity, information coordination, and flow control between the layers. Cloud computing is not a revolution. The dynamic control pane must be able to Intercept traffic as it traverses the cloud, Interpret the data, and Instruct the cloud architecture on how to efficiently connect the user to the appropriate application instance. History. Without this capability, organizations cannot realize the benefits associated with the model. Perform response time impact testing Requirements and best practices are highlighted for each step in the sections that follow. They can have massive numbers of processing cores and memory that can be carved into virtual systems; auto-provisioning network interface cards that can dynamically be configured from 10MB to multi-gigabit; and both direct attached and network-attached storage systems to support the needs of the application software that will eventually reside on top of it. As demand for capacity decreases, the amount of computing resources available decreases appropriately. Visit our self-service resource for product guides, downloads, release notes, solutions to known issues, and more. The following topics are listed here for your review. 2. Supported Operating Systems. Non-functional requirements (NFRs) can be defined as quality attributes (e.g., usability, reliability, security) or general system constraints. For IaaS or PaaS, the functional requirement is simply for infrastructure or platform; unless you need special features – in which case you should probably not be considering a cloud solution – functional fit is not a problem. The commonality type denotes the main non-functional requirements list of cloud service types according to an analysis of QoS-related research [20] [21][22], based on the lists in Table 3. Nothing that approaches a use case other than singular, VMWare, and Windows under VMWare. In addition, the cloud must exhibit additional capabilities that address the best-in-class requirements of the enterprise-such as providing for security, real-time availability, and performance. The dynamic control plane must have the visibility into the data plane and all components that operate within the data plane. There has also been an emergence of a dynamic understanding and need to control what, how, and when the cloud provides services to the consumers of those services. Consider these requirements from the National Gallery of Art in Washington, D.C.: "System shall allow user to click on a link associated with a content object or search result item to generate a preformatted scholarly citation that can be cut and pasted by the user." Recommendation Y.3513 (08/14) - Cloud computing – Functional requirements of Infrastructure as a Service. Cloud-computing provider's platforms must deliver consistent, high-speed systems performance worldwide and provide detailed historical statistics to back up performance claims, including: Functional disaster recovery and business continuity options - Protect customer data by running the service on multiple, geographically dispersed data centers with extensive backup, data archive, and fail over capabilities. However, in order to be truly ready for enterprise deployment, it must also be scalable, adaptable, extensible, manageable, and secure with real-time performance. Challenge: Traditional achievement of NFR (Non Functional Requirements) assurance Software Cloud Platforms Concept must be aligned with Cloud Platform, blocking points -up at concept phase Platform assures non functional requirements as scalability, elasticity, reliability, and features as pay by use, and low cost through economies of scale. These platforms can be environments such as Oracle or ASP.NET and provide a convenient way for businesses to build custom applications without worrying about the details that lay beneath the platforms. We learned to integrate devices: built APIs, consolidated racks of servers in racks of blades and learned to provide automated provisioning. Infrastructure as a Service (IaaS) is a cloud computing model based on the premise that the entire infrastructure is deployed in an on-demand model. One paragraph answers are misleading in their brevity. DoD Secure Cloud Computing Architecture Functional Requirements V2.9 Developed by DISA for the DoD - Publish Date: 01/31/17 view Online. Whether it is a native, purpose-built integration or simply an open standard that can be used by the consumer, the dynamic control plane must be integrated in order to fully intercept, interpret, and instruct or it is not a cloud. This might be a hosting service provider with hundreds or thousands of installed server systems waiting to be used by subscribers or it could be a single blade-chassis with extremely dense resources designed for virtual segmentation. The dynamic control plane must have the ability to understand the elements of context in relation to the individual request, business policy, and other application and cloud traffic. This enables them to react quickly to the ever-changing needs of the business. Cloud-computing platforms must have: Proof of the ability to scale to many subscribers, Resources to guarantee the highest standards of service quality, performance, and security to every customer, The ability to grow systems and infrastructure to meet changing demands, Support that responds quickly and accurately to every customer, Proven performance and reliability as customer numbers grow. At the top of the pyramid is general business computing. Without the ability to intercept traffic and data requests, the dynamic control plane cannot appropriately do any of the other things it needs to do. Software as a Service (SaaS) is a cloud computing model in which pre-built applications (such as CRM, SFA, word processing, spreadsheets, and HRM) are offered to customers via a web browser or other local interface such as a mobile device application. Validation of Non-functional Requirements in Cloud Based Systems (Short Paper) Abstract: Cloud computing that is based on Infrastructure as a Services model, allows the system administrators to identify resources or services to deploy their applications. Users do not care how it was built, where it resides, or the compute resources required to deliver it. Ideally, an IT organization will build a set of services that fit the needs of the business organization. The Practical Guided for Cloud Outsourcing Template includes -- Sample Cloud Outsourcing Contract along with a Service Level Agreement and other tools to facilitate the cloud  outsourcing process. Any component that provides such comprehensive involvement in the applications and data must also be secure and be able to operate in real-time; it cannot degrade security or impede performance. Finally, let’s talk about data modeling requirements. As one of the cloud computing service categories, Infrastructure as a Service provides cloud service customers with computing, storage and network services by cloud … The latter results in the creation of a platform-specific IaaS, with the required components arranged specifically to provision and decommission resources based on the unique needs of the deployment environment. Applications are the only component here. The software system should pass Section 508 accessibility requirement. This might require sending requests to the a new instance of the application or to a new data center, changing compression and encryption settings, or even instructing other components in the architecture to create or destroy resources necessary to delivering that application or data. Microsoft Visual Studio-derived environments are as capable of connecting to internal as external instances of Microsoft-specific platform, thus enabling "offline" development of applications to be deployed in a PaaS environment. Oh, about 1000 pages of specifications last time I checked. However, there are additional, basic fundamental needs of enterprise IT that must be taken into account. The dynamic control plane must constantly evaluate the context and policy to make intelligent decisions at any given moment. At the same time no single definition of cloud computing exists or is being talked about, planned, and even implemented in today's enterprise networks. Included in the requirements are: The need to lower cost, increase efficiency and conserve cash has increased the motivation of companies to turn to Cloud Computing and increased the appeal of alternative delivery models. Based on this approach, commercial factors influencing cloud computing or being subject to the impact of cloud computing are identified. The software system should be integrated with banking API 6. These requirements include scalability, adaptability, extensibility, and manageability. The difference is that today there are vast advances in virtualization in nearly every aspect of the data center. So, what is that final threshold, what is the difference between a cloud and falling short of the cloud? Learn architectural design patterns for managing non-functional requirements (NFRs) that are specific to Platform as a Service (PaaS) environments. 10 Critical Requirements for Cloud Applications Another day, and another software vendor—or two, or three—will announce some strategy around the cloud. In our work, we applied the 80-20 rule where 20 percent of applications within the customer enterprise will serve 80 percent of the services and most of the critical applications are associated with strong non-functional requirements (NFR) like performance and growth. Functional requirements examples. The cloud architecture enables organizations to deploy solutions that naturally meet at the intersection of IT and business. This newer dynamic cloud architecture may bring a wealth of new benefits, but it must still satisfy the basic mandates of enterprise IT and, if the internal systems are going to mesh with external ones, it must provide for consistent and reusable methods of interconnecting the divergent implementations at the cloud providers as well. BASIC REQUIREMENTS OF A CLOUD COMPUTING SERVICE. Manage resources are the components required to turn bare metal into usable server platforms with the appropriate CPU, memory, and disk resources necessary to support the applications that will be built upon them. This component is most often synonymous with virtual machine management or software provisioning systems which can take the bare metal and apply operating systems, patches, and application logic and apply higher-level network connectivity (IP addressing and more). Included in the requirements are: World-class security - Provision world-class security at every level. Service Functionality . Summary. About the only thing that remains to be seen is whether the vendors and manufactures can deliver an enterprise ready dynamic control plane to bring the entire picture together to provide those benefits. The cloud computing architecture is built upon several functional component blocks (for example, compute resources or deployment environments), which are organized into specific layers of a pyramid. This course teaches strategies, services, and patterns best suited for different non-functional requirements. The underlying platform for Salesforce.com, for example, was exposed in recent years as a separate PaaS offering called Force.com, providing customers with additional options for building custom solutions. The commonality type denotes the main non-functional requirements list of cloud service types according to an analysis of QoS-related research [20] [21][22], based on the lists in Table 3. Source: Appendix I of Y.3512 Use Cases Functional Requirements Functional The requirements currently specified within this document pertain only to the security and The cloud is a holistic ecosystem of components, not a point product or single vendor solution, and has basic, specific requirements to meet the needs of enterprise organizations. It is recognized that commercial CSPs, 3 . Functional requirements defined herein are applicable for all CSO environments (i.e., IaaS, PaaS, SaaS). This was all of the functional requirements. You also need to consider different types of integration, including data migration, process integration, or some unique new type of integration, including taking data from an internal application and displaying the data in a SaaS application. A functional requirement can be in the form of a document explaining the expected types of outputs when the device (system) is placed in a certain … These are extremely important when you are going into the cloud for a set of functionalities. Instead of relying on an internal IT organization to build and/or deploy infrastructure and platforms, business stakeholders simply select an application and run it. An organization with limited infrastructure skills can readily purchase IaaS from a vendor and build their own platform (or several) upon that infrastructure without needing the expertise to completely build the infrastructure from scratch. Amongst these where an infrastructure that was scalable, adaptable, extensible, and manageable. Cloud computing – Functional requirements of Network as a Service active, Most Current Details. This document outlines 10 critical requirements of cloud computing to help organizations distinguish the difference between real and fake cloud applications. Whether the application is the result of building utility computing, followed by a platform, or it is simply an application deployed on a server, this is what users interact with. As we established, every functional requirement involves an input, a behavior and an output. 1. Party Providers, and DoD Mission Owners may deliver DoD complian t security solutions with the approval of the assigned Authorization Official (AO). deployed Workday and other cloud applications in his prior role as CIO at H.B. The solution at the minimum should meet the minimum requirements for scalability, availability, fault tolerance, security, replication, and disaster recovery. You need to be able to connect many different types of applications and data quickly and easily without requiring a lot of ongoing maintenance. Abstract. Cloud computing is here to rule. Software as a Service, or SaaS, is the practice of using a network of remote servers hosted on the Internet to store, manage and process data. The greater the capability to provide these services, the greater the ability for the dynamic control plane to operate intelligently and entirely on its own without manual, human intervention. This report is a first step in this direction, as it evaluates privacy and security requirements and concerns of cloud computing from a business perspective. It should clearly define who will be allowed to create/modify/delete the data in the system 6. The width of these layers represents the depth of technical expertise required to build and/or deploy that layer. In the case of a virtualized architecture-the most common form of IaaS architecture-this involves the automatic deployment and launch of new instances of a virtual machine. They are considered as overall solution requirements when establishing the suitability of a cloud solution, as described under Determining Fit, … Cloud architecture is simply the logical conclusion of this decade's long evolution. Most of the applications will move to target cloud environment AS-IS without much change. This is my personal favorite. The question that remains, however, is what does this new dynamic computing architecture look like and what is required-above and beyond the standard tools we have today-to qualify as a "cloud"? A larger scale means a larger customer community, which can deliver more and higher-quality feedback to drive future innovation. A multilevel backup strategy that includes disk-to-disk-to-tape data backup in which tape backups serve as a secondary level of backup, not as the primary disaster-recovery data source. The Sales system should allow users to record customers sales 3. These development environments can be traditional integrated development environments (IDE) that are configured to deploy to resources within a PaaS environment or they can be integrated directly as part of the PaaS offering. This is our world. You may need to make connections between two applications, or you may need to connect one application to many application endpoints. This is where many organizations-especially business organizations-find themselves; with the ability to identify a business need, but without the ability to build an application or the infrastructure upon which it runs. Y.3531 : Cloud computing - Functional requirements for machine learning as a service: Recommendation Y.3531 (09/20) Approved in 2020-09-29. Traditional traffic and computing systems often break processing into two discrete components: the data plane and the control plane. This document provides cloud computing requirements from the business perspective. com-provide a PaaS-hosted development environment through which developers can build, test, and deploy their solutions. Non-functional requirements focus on user expectations, as they are product properties. Correctly balancing that user experience with the controls and policies required by the business is the ultimate goal of cloud architecture. Part 2: Functional requirements and reference architecture . Cloud-computing platforms must have detailed, robust policies and procedures in place to guarantee the highest possible levels of: Compliance, trust and transparency - Provide compliant, transparent, real-time, accurate service performance and availability information. All platforms require a development environment in which the applications are designed, built, tested, and validated-outside of the production environment. The purpose of WP1.3 is to provide an account of privacy and security requirements of cloud computing that derive from the effects of cloud computing on the ways business is done. As one of the cloud computing service categories, Infrastructure as a Service provides cloud service customers with computing, storage and network services by cloud service … All software products are built with a set of Functional as well as Non-functional requirements. So we decided to document the many components that go into cloud applications in an important, educational paper we call the “10 Critical Requirements for Cloud … DISA’s Secure Cloud Computing Arch itecture (SCCA) is a suite of enterprise-level cloud security and management services. These three things necessitate the integration that we alluded to before and underscore the necessity for the inclusion of the dynamic control plane interface at each level and within each component of the cloud architecture. , tested, and Windows under VMWare compute resources also communicate with the controls and policies by!
