Cloud Reference Architecture,Executive Overview, Businesses have entered an era of cut throat competition that demands innovation and agility. at lower costs for survival Business leaders are looking for ways to focus on their core. strengths and delegate non strategic functions to external entities IT functions are being. elevated from support centers to strategic partners that can provide game changing. capabilities to the business units Cloud computing presents a great opportunity to these agile. enterprises to achieve innovation and agility at lower cost. A recent Gartner study states that Cloud computing influences future data center and. operational models and applications must be designed with a Cloud model in mind In order to. achieve this consumer enterprises must partner with a leader in the Cloud space that offers a. broad portfolio of business applications and platforms through a variety of deployment models. including public private and managed services The Gartner study also states that Hybrid. Cloud computing is an imperative which emphasizes the need for interoperable private and. public Clouds that allow easy migration of services across the Cloud boundaries. Successful Cloud adoption requires not only products to build the Cloud but also guidance. around planning and execution of the Cloud initiative Adopting a Cloud strategy may have. impacts that span beyond just the technology architecture influencing business and. organizational strategies Organizations new to Cloud look for tools processes and best. practices to guide them with decisions around Cloud strategy migration and implementation. Defining a Cloud Reference Architecture is an essential step towards achieving higher levels of. Cloud maturity 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, Most enterprise transformations require some kind of organizational change to succeed and. Cloud is not an exception In a way Cloud is a paradigm shift and it leads to shifts in. organizational structure and roles,1 http www gartner com it page jsp id 1971515.
Cloud Reference Architecture, This whitepaper outlines the Cloud Reference Architecture and discusses the key. organizational changes required for Cloud adoption. Cloud Reference Architecture,Introduction, Cloud computing is a significant advancement in the delivery of information technology and services. By providing on demand access to a shared pool of computing resources in a self service dynamically. scaled and metered manner Cloud computing offers compelling advantages in cost speed and. efficiency, Traditionally deployments require applications to be bound to a particular infrastructure This results in. low utilization diminished efficiency and inflexibility Cloud brings in capabilities to allow applications. to be dynamically deployed onto the appropriate infrastructure at runtime This elastic aspect of Cloud. computing allows applications to scale and grow on demand without needing traditional patches or. IT departments and infrastructure providers are under increasing pressure to provide computing. infrastructure at the lowest possible cost There are also a growing number of public Cloud providers. that are looking for ways to build a versatile Cloud Infrastructure to support their clientele To do this. the concepts of resource pooling virtualization dynamic provisioning utility and commodity. computing could be leveraged within the public Cloud or create a private Cloud that meets these. needs Customers driven by concerns over security regulatory compliance control over Quality of. Service QoS and long term costs will build internal private Clouds Private Clouds allow internal IT. providers and application development teams more control of data security to meet their governance. regulations However as the technology matures and these concerns ease we will see more customers. adopting a hybrid Cloud model that makes use of both private and public Clouds using the most. suitable of the hybrid strategies, This whitepaper describes a reference architecture for Cloud Computing using a number of. architectural views and models that include conceptual and logical perspectives This offers a clear. separation between views that describe what capabilities the architecture provides and how those. capabilities are realized This paper also describes how the architecture conforms to well established. architecture principles and how it can be achieved using various Cloud portfolio products from. Cloud in an Enterprise Ecosystem, Why is Cloud Computing important for an enterprise How does it enable and transform enterprise.
applications Figure 1 shows how Cloud strategy fits in and supports an enterprise ecosystem by. providing additional deployment choices to enable business agility and flexible cost structures. Cloud Computing has emerged as one of the most important new computing strategies in the. enterprise A combination of new technologies and processes has led to a revolution in the way that. computing is developed and delivered to end users It promises the ability to deliver applications at a. lower cost,Cloud Reference Architecture,Figure 1 Cloud in an Enterprise Ecosystem. Successful Cloud adoption requires businesses to choose a vendor that offers the following. Broad portfolio of complete and integrated products to build Software as a Service SaaS Platform. as a Service PaaS and Infrastructure as a Service IaaS. Portfolio of Cloud products to build Cloud management layer offering automation security and. reliability, A variety of deployment choices to support the needs of the business and easy migration between. the deployment models, Support for solutions that enable businesses to adopt cloud at a pace that fits their business. Customers vary widely in terms of how rapidly they wish to move to the Cloud and to what extent. they wish to move to the Cloud The vendor should enable customers to evolve and transform to. the Cloud at a pace appropriate for their business. Cloud Reference Architecture,Cloud Solution Portfolio. As organizations adopt Cloud Computing they will need to define a roadmap that aligns with their. own business drivers and clearly identifies their current and future capabilities for delivering IT. services Cloud services and management capabilities need to be identified and prioritized in a Cloud. solution portfolio The ITSO Oracle Practitioner Guide A Pragmatic Approach to Cloud Adoption. defines an approach for Cloud adoption and describes the Cloud Candidate Selection Tool CCST. that can be used in this process, Figure 2 defines a Cloud solution portfolio that illustrates the following characteristics.
A broad spectrum of business applications to support the core business processes and business. operations Examples include Sales Marketing Financials Human Capital Management and Supply. Chain Management, Platforms and frameworks to develop and run custom processes applications and integration. components, Reliable and Highly Available infrastructure components to support the quality of service. requirements of the business, Capabilities to support the build time and runtime Cloud management operations including business. management operations management model management orchestration provisioning security and. policy management, Choice of architecture in terms of deployment and engineering Deployment choices should include. on premise and off premise deployment models Engineering choices range from best of breed. infrastructure to optimized best practice solutions to engineered systems. Figure 2 Cloud Solution Portfolio,Cloud Reference Architecture.
Basic Roles in Cloud Computing, Cloud adoption requires a conceptual understanding of the basic roles involved and the relationship. between them Figure 3 shows the basic macro level roles involved in building deploying to and. using the Cloud Also shown are the services management capabilities and integration points. Figure 3 Cloud Basic Roles, Figure 3 shows the key components of the Cloud infrastructure that are summarized below. Physical resources supporting the Cloud infrastructure and the logical abstraction layer that pools the. physical resources, Cloud Builder that builds and operates the Cloud infrastructure and platforms as a Service. Cloud Application Builder that develops applications for the Cloud and deploys them on the PaaS. platform and offer as SaaS services Cloud Builders support multiple application builders and. applications, SaaS consumers that consume the software services Cloud Application Builders support multiple. SaaS consumers SaaS consumers may have a hybrid model where some functionalities are provided. by the public Cloud and some are provided by the internal private Cloud or traditional IT. Cloud Management infrastructure supporting the Cloud Builder and Cloud Application Builder The. Cloud management capabilities are described in the ORA Cloud Infrastructure document. Application management includes the self service capabilities provided by the Cloud Builder to. provision and manage applications deployed on the Cloud Additionally security and data integration. concerns must be addressed,Cloud Reference Architecture.
The binding agreement between the Cloud Builder Cloud Application Builder or SaaS consumer. should cover the following elements as applicable, Workload specifications that define the exact definition of what will and what will not run on the. Cloud platform Any exceptions to standards must be clearly stated and agreed upon. Subscription terms that include pricing billing and revenue terms. SLA terms to cover the service levels and non functional specifications. Packaging and assembly tools and standards must be agreed upon between the two parties to ensure. that the platform and the application deployed on the platform are compatible. Interface specifications that specify the user interface or API specifications and functionality offered. to the SaaS consumers,Architecture Principles and Guidelines. This section contains high level architecture principles that must be followed for a successful Cloud. architecture The following list is not indented to be an exhaustive set of Cloud architecture principles. instead it provides a starting point for the formulation of more specific Cloud architecture principles. Cloud interfaces and formats must conform to relevant industry standards. The system must present only the information interfaces etc necessary to perform each specific. The architecture should provide monitoring of all aspects of resource usage for the various. dimensions required by both the Cloud consumer and provider. Any Cloud provider s claims of Reliability Availability Security and Performance must be verifiable. Availability should not be limited by inevitable hardware failures. Robust Identity Domain Separation consumers of the system have no exposure to the. consequences of other consumers use of the system, Transparent Architecture and Control consumers have visibility into the design and operation of. the system, Improved Productivity deliver an order of magnitude improvement over current levels of efficiency. and productivity experienced in traditional IT environments. Assured Data Protection consumers are assured of compliance with data privacy standards and. regulations have confidence that removal of data is absolute. Automate Operations consumers runtime of business process services and platform services. involves minimal manual operations, More details on these architecture principles can be found in the ORA Cloud Foundation document.
Cloud Reference Architecture,Conceptual View, The conceptual view of the architecture shown in Figure 4 brings together three key Cloud. perspectives the provider consumer and the broker,Figure 4 Cloud Conceptual View. The role of the Cloud provider is the most important and most complex of all Infrastructure for the. Cloud is usually of unprecedented scale and stringent requirements Implementing the Cloud and. maintaining it to satisfy the SLAs of the consumers requires extensive planning and precise execution. A Cloud provider can spread the costs of facilities across consumers to achieve economies of scale. Facilities expense may include the cost of real estate cooling utilities and rack space among other. The physical infrastructure components may include blades networks engineered systems and storage. practices to guide them with decisions around Cloud strategy migration and implementation states that Cloud computing influences future data center and operational models and applications must be designed with a Cloud model in mind In order to achieve this consumer enterprises must partner with a leader in the Cloud space that offers a broad portfolio of business applications and
