What Cluster requirements does Cloud Service Mesh need?

[anlex_N]

I can not understand: Ensure that the user cluster that you install Cloud Service Mesh on has at least 4 vCPUs, 15 GB memo...
4 vCPUs, 15 GB memory, per node, or 4 vCPUs, 15 GB memory for 4 nodes?

This is the recommended instance size for GKE when deploying within the Cloud Service Mesh in the Google Cloud environment.
Choosing the appropriate instance size 4 Vcpu and 15GB memory  ensures optimal performance and seamless integration with service mesh features.  to know more about the istio , mesh services and futures please go through the  Cloud Operations and Service Mesh with Anthos course in cloud skill boost, please find the link below.

1. 1 instance = 4 vCPUs, 15 GB memory ?

2. 1 node = 4 vCPUs, 15 GB memory ?

3.  4 nodes = 4 vCPUs, 15 GB memory ?

4. 1 instance = 1 node?

Hi anlex_N,

Welcome to Google Cloud Community!

Regarding your concern, each instance/node in the machine configuration must have the following minimum specifications:

• 4 vCPUs — the minimum required CPU cores per node
  
  
• 15 GB memory — the minimum required memory per node
  
  
• 4 nodes — the minimum number of nodes in a cluster

This requirement is setting a minimum resource "cluster" to ensure that when you install your service mesh it has enough nodes, vCPU, and working memory to do its job without crashing or slowing down the actual applications.
