Learn how to plan and execute safer blue-green database deployments while protecting data integrity, application availability, and business continuity. This course explores zero-downtime database migration strategies, schema compatibility, data synchronization, cutover planning, and rollback.

Designed for database administrators, backend developers, DevOps engineers, and reliability engineers, you'll examine blue-green architecture, stateful database challenges, and recovery objectives (RPO/RTO). Discover how expand-and-contract schema migrations, Change Data Capture (CDC), replication, dual writes, and conflict resolution support reliable database transitions. Learn to evaluate transaction handling, connection draining, replication lag, and application retries for lossless cutover. Explore trigger-based synchronization, schema recovery, post-migration data validation, credential management, and Azure SQL deployment orchestration. By the end of this course, you'll be able to design compatible migration strategies, evaluate synchronization methods, develop secure cutover and rollback plans, and assess deployment readiness. What makes this course distinctive is its focus on balancing zero-downtime deployment, data consistency, security, operational complexity, and cost through practical database deployment decisions.
