As AWS announced that support for AWS App Mesh will end on September 30, 2026, it’s important to plan your migration carefully. After this date, the App Mesh console and resources will no longer be accessible. This means rolling back to App Mesh after the support ends will not be possible.
If you are moving from App Mesh to ECS Service Connect, you should prepare a clear backup plan in case you encounter problems during the switch. Here’s what you need to know:
Before September 30, 2026, you can still revert back to App Mesh if necessary. This gives you time to test Service Connect and ensure everything runs smoothly.
Once you’ve started using Service Connect, focus your rollback plan on this new system because App Mesh won’t be available later. Here are some strategies to help you manage this shift smoothly:
1. Use a Blue-Green Deployment. Set up two environments — one with the current App Mesh setup and one with Service Connect. This allows you to switch traffic between them easily, so you can test Service Connect thoroughly before going all-in.
2. Shift Traffic Gradually. Move small amounts of traffic to Service Connect over time. Monitor how it performs and be ready to pull traffic back if needed. This gradual approach minimizes risks.
3. Leverage Service Connect Rollback Features. ECS now offers the ability to revert to a previous, stable deployment if the new setup causes issues. Use automated tools like deployment circuit breakers and monitoring with CloudWatch alarms. If a deployment fails, you can roll back to the last good version quickly.
The key is to complete your migration and test Service Connect well before September 2026. Focus your backup plan on managing versions of Service Connect, since returning to App Mesh won’t be possible once support ends.
Stay proactive in testing and monitoring your transition to ensure a smooth switch. Proper planning now will help avoid surprises later and keep your environment running smoothly.
