DISASTER RECOVERY BY DESIGN: BUILDING RESILIENT ORACLE DATABASE SYSTEMS IN CLOUD AND HYPERCONVERGED ENVIRONMENTS

Disaster recovery (DR) planning has become a critical component of enterprise IT strategy, especially as organizations transition to hybrid infrastructures that combine public cloud and hyperconverged environments.Oracle Database, widely used in mission-critical applications, requires tailored DR solutions that meet stringent recovery objectives while accommodating diverse deployment models.This paper presents a comprehensive, vendor-neutral framework for designing resilient Oracle Database systems across Oracle Cloud Infrastructure (OCI), third-party cloud providers (e.g., AWS, Azure), and hyperconverged infrastructure (HCI) platforms such as Nutanix and VMware vSAN.Leveraging technologies like Oracle Data Guard, Autonomous Database backups, snapshot replication, and Infrastructure-as-Code (IaC) automation, the proposed architecture addresses both traditional and modern DR requirements.A case study from a hybrid healthcare enterprise demonstrates measurable improvements in Recovery Time Objective (RTO) and Recovery Point Objective (RPO), while maintaining compliance with HIPAA and SOX standards.The framework emphasizes proactive Prasad Manda https://iaeme.
