Blue-Green Deployment Strategy
Posted on 21 Aug, 2021
Useful in case you need to continuously roll out updates with almost no downtime
- 1.Basically stands for copying your production container (🟦) to a new one (🟩)
- 2.Applying your changes to the new green container
- 3.Push this container to prod alongside the blue one
- 4.Perform any automated tests / QA
- 5.Gradually redirect your users to the new deployment (load balancing)
- 6.Once the transition completes, the blue container can become a backup in case you need to rollback or it can be dumped
