Database Blog

This article provides a comprehensive guide to building resilient Oracle Database workloads on Amazon EC2, focusing on high availability (HA) and disaster recovery (DR) strategies.

  • Key considerations include Recovery Point Objective (RPO) and Recovery Time Objective (RTO)
  • AWS offers multiple options for Oracle Database deployment, including self-managed EC2 instances
  • Four architecture patterns are discussed for different resilience requirements:
    • Single AZ with S3 backups
    • Multi-AZ with Data Guard
    • Multi-AZ with Oracle ASM and Data Guard
    • Cross-region disaster recovery
  • Critical backup considerations include using RMAN, AWS Backup, and Amazon S3

The article emphasizes the importance of choosing the right architecture based on specific RPO and RTO requirements, with solutions ranging from cost-efficient to highly resilient multi-region configurations.
