How to access different Redis instance in geo replication ?

Question

Hi,

I am trying to create 3 Redis instance in 3 different regions and then link them together for geo-replication. I want to know how the application will access different instances of Redis in different regions?

In my code, do I need to pass different redis connection string based on region or only 1 primary connection string and application itself will connect to nearest instance?

Any help will be appreciated.

Thanks

Shilpa

Hi @Shilpa Kanojiya ,

Welcome to Microsoft Q&A forum and thanks for using Azure services.

As I understand you trying to create 3 Redis instance in 3 different regions and then link them together for geo-replication and want to know how the application will access different instances of Redis in different regions.

You can create a custom migration process by programmatically reading data from an existing cache and writing them into Azure Cache for Redis. This open-source tool can be used to copy data from one Azure Cache for Redis instance to another instance in a different Azure Cache region. A compiled version is available as well. You may also find the source code to be a useful guide for writing your own migration tool.
