ApsaraDB for Redis in Cluster Mode is the way to go!

Migrating to HBase seems like a drastic step just to save on caching. I don't recall that being a recommended approach in our studies, but I could be wrong.

I'm a bit confused about the advantages of using ApsaraDB for Redis in Standard Mode versus Cluster Mode. I feel like Cluster Mode might be more resilient, but I need to double-check that.

I remember practicing a similar question where we had to choose between different caching strategies. I think installing Redis on an ECS instance might not provide the same level of reliability.

Hmm, I'm a bit unsure about the differences between Architecture Building Blocks and regular Building Blocks. I'll need to think this through carefully.

Hmm, I'm not too sure about this one. I'd probably start with netstat to check the network connections, but I'm not confident that's the best approach.

Ah, the classic 'cache or HBase' dilemma. I wonder if they'll also consider implementing a blockchain-based microservices architecture to really make things interesting.
