When you are using the VMware Aria Automation on-premises version, prior to the installation of VMware Aria Automation Plug-in, you must configure a MID server. The configured MID Server acts as a communication bridge between the ServiceNow platform and the VMware Aria Automation.
Refer to the ServiceNow documentation to install a MID Server.
For the Utah release, see ServiceNow Utah Release Documentation.
For the Tokyo release, see ServiceNow Tokyo Release Documentation
For better performance, use a dedicated MID Server for the VMware Aria Automation Plug-in.
