our Customer is planning to have a 3 Node IFS Cloud Middle Tier Cluster and has asked for the Sizing of the three nodes. The available sizing for the Remote Deployment is based on a single Node Installation, and seems a bit high, when having 3 Nodes.
The Customer has round about 300 concurrent Users.
Do you have any Sizing, and also a recommendation how to scale the IFS Cloud Pods along the Cluster?
Thank you in advance.
For Kubernetes clusters (specifically the control plane), quorum needs to be maintained which means that at least 2 out of the 3 nodes must be available. So based on that, I believe you should be able to allocate nodes such that each node has enough resources to run the application with just 2 nodes available.
Beyond that, the sizing depends on how you want to scale each micro-service/pod/deployment.
