Cloud credits only: Size Cloud Load Generators

Sizing Cloud Load Generators is a crucial step to define the number of User Paths which a Cloud Load Generator can handle. The number of User Paths depends on many aspects:

• Technologies used in the application to test
• Complexity of the application to test
• Network connection capacity
• Etc.

Starting a ramp-up test of the application with one Cloud Load Generator using an on-demand session in one given geographical region makes it possible to benchmark the Load Generator. NeoLoad monitoring data, and particularly thresholds on the CPU and on the memory of the Load Generator machine, help identify the maximum number of User Paths for the Load Generator.

After identifying the number of User Paths that one Cloud Load Generator can handle and the number of User Paths for the test, it is easy to calculate the number of Cloud Load Generators necessary to run the test.
