vRealize Automation 7.3 Distributed Install – Prerequisites

Pre-requisites - Get your ducks in a row!As a consultant I’ve had the opportunity to design, install and configure dozens of production vRealize Automation deployments, from reasonably small Proof of Concept environments to globally-scaled multi-datacenter fully distributed behemoths. It’s fair to say, that I’ve made mistakes along the way – and learned a lot of lessons as to what makes a deployment a success.

In the end, pretty much everything comes down to getting the pre-requisites right. Nothing that I’ve written here is not already documented in the official documentation, and the installation wizard does a huge amount of the work for you.

For the purposes of this post, I am working with the following components, which have been pre-deployed on a single flat network.

vCAC 6.0 build-out to distributed model – Part 2: vPostgres

This is the second article in a series about how to build-out a simple vCAC 6 installation to a distributed model.

The diagram below shows the deployment at the end of this part, with vPostgres deployed and the vCAC Appliance running from the remote database.
