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