Cassandra + Redis Project Server setup

Currently i'm having a Dedicated VPS Server with 4GB Ram , 50GB Hard-disk , i have a SAAS solution running on the server with more than 1500 customers. Now i'm going to upgrade the projects business plan,There will be 25000 customers and about 500 - 1000 customers using the project realtime . For now it takes 5 Seconds to fetch cassandra database records from the server to the application.Then i came through redis and it says that saving a copy to redis will help to fetch the data much faster and lowers server overhead.

Am i right about this ? If i need to improve the overall performance , Can anybody tell me what are the things i need to upgrade ? Can a server with configuration said above can handle cassandra and redis together ?

Thanks in advance .

A machine with 4GB of RAM will probably only be single-core so it's too small for any production workload and only suitable for dev usage where you run 1 or 2 transactions per second, mostly for functional testing.

We generally recommend deploying Cassandra on machines with at least 2 cores + 8GB allocated to the heap (so need at least 16GB of RAM) for low production loads. For moderate loads, 4 cores + 32GB RAM is ideal so you can allocate 16GB to the heap.

If you're just at the proof-of-concept stage, there's a tier on DataStax Astra that's free forever and doesn't require a credit card to create an account. I recommend it to most people because you can launch a cluster in a few clicks and you can quickly focus on developing your app. Cheers!
