Using vSphere Tags to Drive Automation Tasks with PowerCLI — Wahl Network
The use of metadata (in this case, tags) is a helpful way of abstracting what a piece of data is from what a piece of data contains. For instance, if I want to know if a particular virtual machine is running SQL Server, I could launch an RDP session, do a port scan, or try to connect to the database engine. There are many options. Alternatively, I could tag that virtual machine with a SQL Server identification and know, without examining the virtual machine itself, that it is running a database server. In short: tags are pretty cool, but often underutilized.
