Disaster recovery strategies for Amazon MWAA – Part 2
Big Data Blog
This article discusses disaster recovery strategies for Amazon Managed Workflows for Apache Airflow (Amazon MWAA). It covers two main strategies: backup and restore, and warm standby.
Specifically, the article covers:
- Backup and restore architecture: Periodically backing up Amazon MWAA metadata to Amazon S3 in the primary region, replicating backups to a secondary region, and restoring from the backups in case of a primary region failure.
- Warm standby architecture: Deploying identical Amazon MWAA environments in two regions, with the secondary environment acting as a warm standby ready to take over by restoring metadata backups from the primary region.
- Key considerations for each strategy, including Recovery Time Objective (RTO), Recovery Point Objective (RPO), cost, data loss, and ongoing management.
- Shared considerations for both strategies, such as testing failover, enabling logging, using infrastructure as code, automating deployments, and monitoring for failure detection.
- Conclusion: Both strategies offer configurable data protection based on RTO, RPO, and cost requirements, using periodic metadata replication and restoration to minimize the impact of regional outages.
