Oracle Database High Availability On-Premises and in the Cloud

Oracle White Paper

Introduction

Enterprises are under intense pressure to do more with less, reduce risk and increase agility. The aggressive consolidation of information technology (IT) infrastructure and deployment of Database as a Service (DBaaS) on public and private clouds is a strategy that many enterprises are pursuing to accomplish these objectives.

Database consolidation drives cost savings by dramatically improving system utilization and reducing management overhead. DBaaS drives cost savings and increased agility through the standardization of I.T. infrastructure and processes. The Cloud enhances these benefits by enabling a more efficient utility model of computing.

All of the above initiatives, however, also incur business risk by amplifying the impact of downtime and data loss. The failure of a standalone environment used by a single developer or small work group is usually of limited impact. The failure of a critical application running in a traditional standalone environment will be immediately felt by the business, but other applications can continue to run unaffected. In contrast, an outage of a consolidated environment supporting an organization’s entire development staff or multiple applications used by numerous departments would have a crippling effect on the business. Equally crippling would be an interruption in service at a cloud provider where such applications are running.

The Oracle Maximum Availability Architecture (Oracle MAA) prescribes four HA reference architectures that provide the requisite level of standardization for DBaaS while addressing the complete range of availability and data protection required by enterprises of all sizes and lines of business. All reference architectures are based upon a common platform able to be deployed onpremises or on cloud. This approach makes Oracle MAA simpler and less risky to move to the cloud.

This paper describes Oracle MAA reference architectures in detail and the service level requirements that they address. It is most appropriate for a technical audience: Architects, Directors of IT and Database Administrators responsible for designing and implementing DBaaS and moving to the cloud.
