Cloud initiatives are beginning to dominate enterprise IT roadmaps. Successful adoption of Cloud and the subsequent governance challenges warrant a Cloud reference architecture that is applied consistently across the enterprise. This presentation will answer questions such as what exactly a Cloud is, why you need it, what changes it will bring to the enterprise, and what the key capabilities of a Cloud infrastructure are - using Oracle's Cloud Reference Architecture, which is part of the IT Strategies from Oracle (ITSO) Cloud Enterprise Technology Strategy (ETS).

4. Introduction

5. 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.
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

6. Definition of “Cloud Service”
Cloud services are self-contained units of functionality or IT
capability offered through cloud computing to its consumers.
Cloud service offerings range from managed units of
computing infrastructure (such as storage) through
platforms (database, web containers, etc.) all the way to
complete software solutions (e.g. finance, HR, etc)
• Cloud Services don’t necessarily refer to
• SOA Services
• Web Services
• Helpdesk Services
• …
