VM Sizing for Concurrent connections

Question

We're planning to set up an environment where around 60 people will be connecting simultaneously to two servers. The users will be performing lightweight tasks, without running any databases or creating applications. I have a couple of questions regarding this setup:

We're considering using Azure Bastion Premium to support these 60+ connections to the servers. For the VM size, we are looking at D8asv5 (8 vCPUs, 32 GB RAM). Will this configuration be sufficient to handle the load, or should we adjust the VM size?

If a user connects to both Server-1 and Server-2, do we need two separate RDS licenses for that user, or can a single license cover both servers?

Answer 1

Hello,

Welcome to Microsoft Q&A,

The D8asv5 VM (8 vCPUs, 32 GB RAM) is a solid choice for lightweight tasks, but the suitability depends on the specific workloads and concurrent connections. CPU and RAM demand will increase if each user runs multiple remote sessions. If users open multiple applications, even lightweight ones, the available RAM per user may become a bottleneck. Monitor performance via Azure Monitor & Performance Counters, and consider scaling up to D16asv5 (16 vCPUs, 64 GB RAM) if necessary.

If you are using per-user RDS CALs, a single license will cover both servers for that user.
