You can install vRealize Automation through different means, each with varying levels of interactivity.
To install, you deploy a vRealize Automation appliance and then complete the actual installation using one of the following options:
A consolidated, browser-based Installation Wizard
Separate browser-based appliance configuration, and separate Windows installations for IaaS server components
A command line based, silent installer that accepts input from an answer properties file
An installation REST API that accepts JSON formatted input
You can also install vRealize Automation using vRealize Suite Lifecycle Manager. See the vRealize Suite documentation.
