Hi,
You had a name change at some point but basically :
- you have a on "premise" version that you can install on your own machine
- Visual Studio Online being the "cloud version" (I believe both were named "Visual Studio Team Services" as they are basically the same and then they switch to "Online" to clearly stress when they refer to the "online" version)
Edit: As you are in an Azure forum you perhaps saw the option to subscribe to the "online" version (for example updates to the service will be deployed by MS) or to use a VM Template including this service and then manage this yourself.
