This research conducts comparative analysis and performance evaluation on disaster recovery approaches, encryption strategies, and database migration methods in cloud environments. The study highlights deeper technical insights encryption techniques and demonstrates superior performance compared to the other encryption methods in securing non-data files. This approach enhances protection against insider threats while avoiding reliance on existing Oracle wallet features, ultimately leading to a reduction in licensing expenses. This study also evaluates various database migration solutions, specifically AWS DMS, Google DMS, Azure DMS, and IBMS. Notably, IBMS stands out for its proficiency in producing cross-region data copies while achieving a 75% reduction in infrastructure costs. A comparative analysis was conducted on various disaster recovery strategies, including Standard DR, Pilot Light, Warm Standby, Hot Standby, Semi Replication, and DDI. Among these, the DDI is being observed as noteworthy since it excels in decision making capabilities and auto replication role switching advantages of standby databases.
