Scaling CSM

There are two ways to scale CSM. One is to horizontally scale high-impact services, such as the Automation Process and the Email and Event Monitor. The other is to implement a server farm to load balance the CSM web applications.

In most cases, CSM will perform well without additional scaling. If you see performance spikes over time, you may choose to scale the Cherwell Service Host, the CSM web applications, or both. You can also try increasing the RAM and CPU on the CSM server before using one of the more advanced methods.

The scaling method you use depends on these factors:

• Scale the Cherwell Service Host only.

  If you use a lot of automation, such as Automation Processes and One-Step Actions, consider scaling the Cherwell Service Host. See Scaling the Cherwell Service Host.

• Scale the web applications only.

  If you have a large number of people using the system at the same time, consider scaling the web applications. See Scaling the CSM Web Applications.

• Scale the Cherwell Service Host and the web applications.

  If you use a lot of automation and you have a large number of people using the system at the same time, you can scale the Cherwell Service Host and the web applications.
