We have one webapp running on Azure, which pushes data to Azure Redis, then we have an on-prem component which reads that data from Azure redis and processes that. Recently due to Azure region failure that Azure Redis went down. Web app and my on-prem component was not able to contact Azure redis.

How can I make sure zero down time for my web app to access Azure redis ? Redis-GeoRelication doesn't solves my problem as it is unideirectional, and Manual failover. Also my web app and on-prem component need to know both redis endpoint, and contact accrondignly. which is not seemless.

Azure redis doesn't support cluster having shards in multiple region.

So my requirement is, Web-app and on-prem component both need to contain one cache/database endpoint ( without having any knowledge about the replication of the cache/database). if primary cache/db fails then, that endpoint should automatically goes to replicated cache or DB.

As per Documentation from Azure, it doesn't seem Azure Redis is correct fit for this requirment, is there any other Azure component which fits this requiremnet.
