Cassandra and GCP

[Manu Chadha <ma...@hotmail.com>]

Hi

I am moving my MVP application to GCP. It is a general web application with standard database workload (CRUD). I am not expecting much traffic to begin with.

I don’t have any experience in putting applications in production. Would it be possible to change the machine configuration later (CPUs, disk size) for Cassandra when the traffic load increases? Would I have to stop the application completely when I am upgrading or would I be able to do rolling upgrade?

Any tips on how to approach upgrade later would be most appreciated.

Thanks
Manu

Hi,

First, you should deploy with the minimal configuration required for the
production. More details can be found from Cassandra doc here =>
https://cassandra.apache.org/doc/latest/operating/hardware.html

Also, to ensure reliability and fault tolerance you should configure your
cluster to have more than one replica/node (3 is the recommended
replication factor) deployed in two or more region/zone... So, in case of
upgrade/maintenance operation/ unavailable zone... you can switch your
clients to request your second Data Center

Finally, Cassandra is linear scalable, so your cluster can be increased by
simply adding new nodes when your traffic load increases :)

Cheers,
