We’re happy to announce that Elastigroup now supports blue/green deployments on Gooogle Cloud!
Blue/green deployments let you test new application versions before they handle 100% of production traffic. If there’s an issue with the newly deployed application (i.e your instances do not become healthy or return HTTP errors), the blue/green deployment process will fail and the newly created instances will be terminated.
To run blue/green deployments Elastigroup provisions a new set of instances in batches based on your preferred batch size. The latest version of your application is installed on each instance in the batch by using a new Image or start-up script. After the new instances are deemed healthy, Elastigroup reroutes traffic from the existing set of instances (Blue) to the new set of instances running the latest version (Green).
