Deployment best practices
In this section, we are going to describe some best practices related to the deployment process. These practices, listed here, will help you to set up a reliable deployment process for your microservices:
- Automated rollbacks
- Canary deployments
- Continuous deployment (CD)
Automated rollbacks
Automated rollbacks are the mechanism of automatically reverting a deployment in case there was a failure during it. Imagine you are making deployment of a new version of your service and that version has some application bug that is preventing it from starting successfully. In that case, the deployment process will replace your active instances of a service (if the service is already running) with the failing ones, making your services unavailable. Automated rollbacks are a way to detect and revert such bad deployments, helping you to avoid an outage in situations when your services become unavailable due to such issues.
