High Availability for Oracle Databases in the Public Cloud

This white paper discusses the implementation of high availability for Oracle databases in public cloud environments using Veritas Alta™ Enterprise Resiliency. It outlines how this solution enhances database performance, security, and resiliency compared to traditional Oracle Real Application Clusters (RAC). The paper details the limitations of Oracle RAC and presents Veritas Alta as a compelling alternative that offers significant benefits, including public cloud integration, improved performance, and advanced security features. It describes the solution's capabilities in providing fast failover, disaster recovery, and data protection against ransomware attacks. Additionally, the document explains the components of Veritas Alta Enterprise Resiliency, such as Veritas File System and Volume Manager, which contribute to its effectiveness in managing Oracle databases. The paper emphasizes the flexibility of deploying this solution across various public cloud platforms, ensuring high availability without vendor lock-in. Deployment recommendations and guidance for transitioning from RAC to a single-instance configuration are also provided.
