The steps of starting this workbench is the same with the procedure of spinning up an instance of our RStudio Server product.
t3.xlarge is a good starting point for testing. Once everything is confirmed to work, you can switch to other instance types (more CPUs, high memory) that fit your need.
If you do not already have an SSH key pair, please generate a new one to use when logging into the RStudio Server.
To change the instance type once the server is tested, please go to "Launch instances", "Instance settings", and then "Change instance type".
