In addition to subscription limits, the total capacity of clusters in each workspace is a function of the masks used for the workspace's enclosing Vnet and the pair of subnets associated with each cluster in the workspace. The masks can be changed if you use the Bring Your Own Vnet feature as it gives you more control over the networking layout.
Worth noting that in Azure
- Each cluster node requires 1 Public IP and 2 Private IPs
- These IPs are logically grouped into 2 subnets named โpublicโ and โprivateโ
- For a desired cluster size of X: number of Public IPs = X, number of Private IPs = 2X
