Oracle Database Migration, High Availability, and Disaster Recovery Strategies in Hybrid Cloud Environments for Saudi Enterprises
Abstract
Saudi enterprises are modernizing mission-critical Oracle estates under two pressures: faster digital delivery and stronger resilience under regulatory, operational, and cyber risk. Hybrid cloud is attractive because it allows sensitive databases to remain on premises or in controlled deployments while enabling cloud-based scale, automation, geographic separation, and managed recovery options. Yet migration projects often underperform because cutover planning, high availability design, and disaster recovery architecture are treated as separate workstreams. This paper presents a structured review of 2020-2025 literature, standards, and vendor documentation on Oracle database migration, high availability, and disaster recovery in hybrid cloud settings relevant to Saudi enterprises. A PRISMA-informed review protocol defined scope, screened sources, and synthesized evidence across migration methods, Oracle Maximum Availability Architecture patterns, Oracle RAC, Oracle Data Guard, Zero Downtime Migration, Oracle Database Azure, and Saudi governance controls. The review finds that successful programs follow an integrated continuity pipeline: classify workloads and residency obligations first, choose the target topology second, select a migration path with explicit rollback, engineer local availability at the primary site, and then map disaster recovery and cyber recovery controls to measured RPO and RTO targets. The paper contributes a Saudi-focused synthesis, two design figures, and two decision tables that translate recent evidence into implementation guidance suitable for a review article aligned to Springer or Elsevier conventions.
