One of the use cases I’ve been working on with a customer is based on the vRO/vCO multi-node plug-in and involves the master vRO/vCO node calling proxy workflows based on a parameter - in this case the target site. As you can see from this very simple diagram, a Cloud Management System (CMS) calls a workflow on the Master node, which then executes a proxy workflow on the correct site. The trick is getting the Master Orchestrator node to pick the right proxy workflow.
To quote the release notes for the latest version of vCO/vRO Multi-node Plugin: The VMware vCenter Orchestrator Multi-Node Plug-In allows organizations to manage environments with multiple vCenter Orchestrator server instances. As organizations increase their level of automation, they often find the need to deploy multiple Orchestrator instances. With the VMware vCenter Orchestrator Multi-Node Plug-In, administrators have a more efficient way to manage multiple Orchestrator instances from a central point. The plug-in allows administrators to log in to a master Orchestrator server to view the inventories and workflows of remote Orchestrator servers, and to trigger workflows remotely.
Using System Center Operations Manager 2007 R2 Audit Collection Services for remote, DMZ or workgroup servers
SCOM 2007 R2’s Audit Collection Services (ACS from now on) is very useful for meeting compliance (e.g. Sarbanes Oxley) and security audit requirements – working with financial companies often requires such compliance. It’s pretty simple to install in a domain environment – you run the installer to create a collection server, then activate the forwarder on the client servers. When it comes to servers you really want to audit, those that are by definition more at risk from security breach because they are publicly accessible, it’s not so straightforward.
