IT-as-a-Service: Cloud Computing and the Evolving Role of Enterprise IT
3 likes2,755 views
The document discusses Oracle Enterprise Architecture and IT-as-a-Service. It provides the NIST definition of cloud computing which describes cloud models as enabling on-demand access to shared configurable computing resources that can be rapidly provisioned. The definition notes the essential characteristics of cloud computing include on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It also lists the common cloud service models of SaaS, PaaS, and IaaS and deployment models of public cloud, private cloud, community cloud, and hybrid cloud. Finally, it outlines how cloud computing impacts different layers of IT architecture from a business, application, information, and technology perspective.

- 3. NIST Definition of Cloud Computing Cloud computing is a model for enabling convenient, on- demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of: 5 Essential Characteristics 3 Service Models 4 Deployment Models • On-demand self-service • SaaS • Public Cloud • Resource pooling • PaaS • Private Cloud • Rapid elasticity • IaaS • Community Cloud • Measured service • Hybrid Cloud • Broad network access Source: NIST Definition of Cloud Computing v15

Business • Change Management and Control - How to align the competing needs of consumers and suppliers of services? • Service Provisioning • How to automate and streamline the creation and deployment of Application application platform stack? • How do you ensure tenant isolation and protect information? • Monitoring and Reporting - How to gain understanding what is Information happening inside the cloud? • Dynamic Scaling - How do you enable capacity scale-up / scale-down? • Unified Develop, Test and Deploy experience Technology • Identity and Access Management

Key Takeaways • Enterprise Architecture (tools, frameworks, methods, best practices & processes) is key to aligning IT cloud strategy with business goals • A cloud computing strategy does not need to “boil the ocean”: you can start with building blocks like Database-as- a-Service, then Middleware-as-a-Servirce and realize immediate benefits • Cloud computing isn’t just a hardware deployment: it is about people, process, and technology • Oracle now uses use Troux to help us manage EA Deployments with our customers Copyright ©2010 Oracle Corporation.
