Create a fallback migration plan for your self-managed MySQL database to Amazon Aurora MySQL using native bi-directional binary log replication
Database Blog
This article provides a step-by-step guide on how to set up bi-directional replication between an on-premises MySQL instance and an Amazon Aurora MySQL instance. It covers three potential use cases for bi-directional replication: simplified fallback plan for migration, incremental multi-tenant migration, and separate migration of applications using mutually exclusive tables or schemas.
Specifically, the article covers:
- Enabling binary logs on the on-premises MySQL instance
- Creating a custom Aurora parameter group to enable binary logs
- Backing up the source database using Percona Xtrabackup and restoring to Aurora
- Configuring bi-directional replication between the on-premises MySQL and Aurora MySQL instances
- Validating replication status and monitoring replication lag
- Testing bi-directional replication during an Aurora high availability failover event
The article concludes by emphasizing that bi-directional replication can provide flexibility and reduced risk when migrating to Amazon Aurora MySQL, and encourages readers to explore the other capabilities of Amazon Aurora MySQL.
