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.
One of the trickiest parts of deploying vRealize Automation is the IaaS layer - people sometimes look at me like I’m a crazy person when I say that, normally because they’ve deployed a PoC or small deployment with just a single IaaS server. Add in 5 more servers, some load balancers, certificates, a distributed setup and MSDTC to the mix and you have a huge potential for pain! If you’ve followed my previous posts, you’ll see know that I’ve got a HA Platform Services Controller configured, and a HA vRealize Appliance cluster configured with Postgres replication - all good so far.
