Database Blog
The article discusses how the Amazon TimeHub team designed a resilient data replication framework using AWS Database Migration Service (DMS) to replicate data from an Oracle database to Amazon Aurora PostgreSQL.
- Implemented a multi-AZ architecture with redundant source and target databases
- Extensively tested failure scenarios across source, DMS, and target systems
- Developed comprehensive monitoring framework using CloudWatch metrics
- Tracked key performance indicators like propagation delay, latency, and system resource utilization
- Created custom metrics to validate data integrity and track replication health
The solution ensures high availability and data accuracy for the critical workforce management system by implementing robust failover mechanisms and continuous monitoring across the entire data replication pipeline.
