Disaster Recovery in the Oracle Cloud — A Use Case

Recently, VLSS took on an engagement with an organization that had no disaster recovery (DR) solution in place. The initial phase was to develop a DR Proof of Concept (POC) within a two-week timeframe.

This organization has an on-premise data warehouse and a stack consisting of an Oracle® database, an Oracle Business Intelligence Enterprise (OBIEE) server, and Informatica®. The database is backed up locally with Recovery Manager (RMAN). All components are running in VMware®. The POC’s objective was to take the company’s on-premise environment and replicate it that to the Oracle Cloud to achieve a 48-hour Recovery Point Objective (RPO) and a 24-hour Recovery Time Objective (RTO).
