For our Demand plans, we use m5.xlarge instances through AWS: https://aws.amazon.com/ec2/instance-types/m5/ . Each one comes with 4 vCPUs, 16 GB of RAM and supports up to 10 Gbps. To give you an indication, these are our recommended figures for the number of users that can be run on one node for each of the tools we support:
- JMeter: 1000 users
- Gatling: 1000 users
- Selenium: 5 users
- Flood Element: 50 users
For our Hosted plans, you are able to choose a variety of instances depending on the ones you choose to use on your own AWS account.
