How to deploy ArcGIS Enterprise Blue-Green Environments.

[AYUSHYADAV]

Hi,

Nowadays, blue-green environments are getting more popular as they provide the benefit of near-zero downtime and rollback capabilities. For more reference - https://docs.aws.amazon.com/whitepapers/latest/blue-green-deployments/introduction.html

I have found an ESRI documentation on it but ut doesn't contain any steps how wecan achieve this - https://architecture.arcgis.com/en/framework/architecture-practices/architectural-foundations/design...

I just wanted to understand:-

1. How can we deploy the environment so that both (Blue-Green) environments are in sync in terms of the portal content directory, server configuration directories, and folders?

2. How to quickly switch between the environments from the cloud end and from the ArcGIS end?

Any suggestions/ideas will be highly appreciated!

Thanks,

Ayush

This is achieved using the DR tool and geographic redundancy:

The blog below covers some additional information related to hostname resolution when setting up a new, replicated environment in the context of migrating, not geographic redundancy, but the concepts still apply:
