Now let’s look at the Service Model of Cloud Application/Software as a Service (Apps/SaaS) Transcript IEEE eLearning Library Cloud Service and Deployment Models Transcript pg. Business Support Services ABBs of the Cloud Ecosystem Reference Model The IoT Reference Model also allows the processing occurring at each level to range from trivial to complex, depending on the situation. This paper presents the first version of the NIST Cloud Computing Reference Architecture (RA). Cloud computing, or what is simply referred to as the cloud, can be defined as an Internet-based computing that largely offers on-demand access to computing resources. The following standard services will reduce complexity and simplify the enterprise business operations. It is called ISO-OSI (Open Systems Interconnection) Reference Model because it deals with connecting open systems. NIST defines four cloud deployment models: public clouds, private clouds, community clouds, and hybrid clouds. Cloud Computing Architecture - Cloud Computing architecture comprises of many cloud components, which are loosely coupled. Background NIST : The goal is to accelerate the federal government’s adoption of secure and effective cloud computing to reduce costs … But it should be made clear that client software applications are not part of the application layer; rather the application layer is responsible for the protocols and data manipulation that the software relies on to present meaningful data to the user. 6 / 15 These are complete applications on the cloud … The model describes how tasks at each level should be handled to maintain simplicity, allow high scalability, and ensure supportability. This is the only layer that directly interacts with data from the user. Figure 1 – IBM Cloud Computing Reference Model We recently spent a day with IBM discussing its Cloud Computing approach. –Relates different cloud services and maps them to the overall model –Serves as a roadmap for IT to understand, select, design and/or deploy cloud infrastructures • This report presents the first version of the NIST Cloud Computing Reference Architecture. This expert guidance was contributed by AWS cloud … In cloud computing, the ecosystem consists of hardware and software as well as cloud customers, cloud engineers, consultants, integrators and partners. In general, Reference Architectures (RAs) are becoming useful … A reference model … In 1984, after years of having separate thoughts on networking standards, the International Organization for Standardization (ISO) and the International Telegraph and Telephone Consultative Committee (CCITT) jointly published the Open Systems Interconnection Reference Model, more commonly known as the OSI model. How do we know?Cloud computing governance is a IBM Rational Unified Process (RUP) defines a reference architectureas follows: From this, we can see that a reference architecture is a very powerful tool that can help you achieve your goal in a fast manner with the least possible risk. NIST Cloud Computing Reference Architecture 2. So the data in the cloud should have to be stored in an encrypted form. … The cloud infrastructure can be … Cloud Computing Architecture: Front End and Back End Cloud computing resources are delivered by server-based applications through digital networks or through the public Internet … Certain cloud … The AWS Architecture Center provides reference architecture diagrams, vetted architecture solutions, Well-Architected best practices, patterns, icons, and more. A SRA is an abstract architecture without implementation details showing a conceptual model of security for a cloud system. These resources comprise of many things, such as application software, computing resources, servers and data centers etc. Application layer protocols include HTTPas well as SMTP (Simple Mail Transfer Protocol is … Cloud computing … Werner Vogels, CTO at Amazon, first compared the cloud to an ecosystem in a keynote address at the Cloud … Cloud Deployment Models A cloud infrastructure is the collection of hardware and software that enables the five essential characteristics of cloud computing. SCORM, which stands for Shareable Content Object Reference Model, is a set of technical standards for eLearning software products. Cloud … It not only defines the domain but also sets taxonomy and drives coherency of approach amongst the many authors who contribute to the Private Cloud Reference Architecture documentation set. The broad divisions of cloud architecture are: Front-end; Back-end; It is the back-end responsibility to provide data security for cloud users and the traffic control mechanism. Software applications like web browsers and email clients rely on the application layer to initiate communications. Others say that cloud computing is a business model rather than a specific technology or service. It is a set of control-based technologies & policies adapted to stick to regulatory compliances, rules & protect data application and cloud technology infrastructure. 2. Are we doing them the right way? Cloud Computing refers to manipulating, configuring, and accessing the hardware and software resources remotely. Cloud Reference Architecture addresses the concerns of the key stakeholders by defining the architecture capabilities and roadmap aligned with the business goals and architecture vision. According to NIST, “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources–e.g., networks, servers, … Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user. 1. Finally, the model … It offers online data storage, infrastructure, and application. In our opinion, cloud computing consists of both technological and business components. Because of cloud's nature of sharing resources, cloud security gives particular concern to identity management, privacy & access control. Academia.edu is a platform for academics to share research papers. Business Support Services provide the business-related capabilities needed to simplify and support the end-to-end business activities of an enterprise Cloud Ecosystem. Public cloud is the classic cloud computing model, where users can access a large pool of computing power over the internet (whether that is IaaS, PaaS, or SaaS). A cloud deployment model is defined according to where the infrastructure for the deployment resides and who has control over that infrastructure. As an extension to the above NIST cloud computing definition, a NIST cloud computing reference architecture has been developed by the NIST Cloud Computing Reference Architecture and Taxonomy Working Group that depicts a generic high-level conceptual model for discussing the requirements, structures and operations of cloud … Resides and who has control over that infrastructure this paper presents the first version of the NIST cloud Computing comprises...
