You can now check whether a configuration change will require a blue/green deployment from the Amazon OpenSearch Service console or using the Amazon OpenSearch Service APIs. With this new option, you can plan and make configuration changes that require a blue/green deployment when your cluster is not at its peak traffic.
Previously, you had to depend on documentation to identify whether a change would require a blue/green deployment, and even then in certain scenarios, it was not completely deterministic. Now, when you make a configuration change using the Amazon OpenSearch Service console, you can use the ‘Run Analysis’ option to check whether the change will require a blue/green deployment before you actually make the change. Depending on whether the configuration change requires a blue/green deployment, you can plan to make the change at a time when the cluster is not experiencing its peak traffic, helping you avoid any disruptions or latency during a blue/green deployment for your users. You can also check whether a change will require a blue/green deployment through the configuration APIs by using the new ‘DryRun’ parameter when calling UpdateDomainConfig API.
The new blue/green check is available across 23 regions globally. Please refer to the AWS Region Table for more information about Amazon OpenSearch Service availability.
