Scale-out VMware Identity Manager


Recently I’ve worked with one of my customers to scale-out their vRealize Automation (vRA) environment enabling High Availability for their VMware Identity Manager (vIDM) appliances

Initially they deployed the environment with a single node and as the solution became successfully and the key point of their automation strategy, increasing the availability of it looked like a good idea.

 It’s a smart customer, they deployed the solution through the use of vRealize Suite LifeCycle Manager (vRSLCM) which comes as no extra cost for all vRealize Suite users. 

Besides deploying the solutions, it also takes cares of all day 2 activities, like patching, upgrading and scale-out as well.


Although the platform will take care automatically of the scale-out activity, provisioning new nodes, configure them as a cluster, replacing certificates for VIPs, etc...there’s still just a few tasks you need to take care first.

-       Replacing the certificate to include SAN for VIP and extra vIDM nodes;

-       Register the vIDM VIP FQDN on DNS system;

-       Configure the external Load Balancer to handle the requests.

That’s when we realized vRSLCM’s documentation does not include much information about it, like health checks, ports, HTTP method, etc.

So I had to dig this information from several other documentation and it’s here for easier consumption.

Be aware of an issue scaling vIDM 3.3.1 with vRSLCM 8.x 
If your environment match this specific matrix, check KB79040 for the fix


I'm adding here the source information if you need to check for yourselves ; )

- Create Service Monitors for the Cross-Region on VMware Validated Design's documentation
