I'm looking for some advice on azure k8 and nextjs caching.

We plan to implement a nextjs solution in azure k8. Has anyone any experience/insight on a good way to share the cache between the instances?

I've looked into using a shared file share in azure vs a rediscache/memcache, set as a service in the cluster. I'm leaning towards a redis cache solution.

Is this a typical way to go or is there better alternatives? Any advice or pitfall warnings is appreciated (or any good related threads)!
