The answer varies widely depending on the type of work you are doing and how your teams are organized. Based on our observations so far, both RStudio Server and RStudio Server Pro can handle tens of concurrent connections per server, if the server is beefy and the workloads are reasonable. However, the organizations we talk to often set up one server for each working group, simply because it suits the way they organize their work.
To help you determine the right configuration of servers, RStudio Server Pro includes all the tools your IT team needs to be able to size and allocate resources to optimize your scientists’ and analysts’ experience with R as your deployment scales. We offer a 45 day evaluation period for RStudio Server Pro so that you can compare and see what works for you.
