A customer asked the following question on the PlateSpin Migrate product page, and we tracked down the answer from Jason Dea.
Q: What is a workload, according to PlateSpin? Is it a single P2V migration or is it based on the number of applications running on a physical machine that need to be moved over to a virtual machine?
A: A workload is the logical “software stack” that would be residing on compute resources. For example: OS, Middleware (if applicable), Application, Data (if applicable).
I think of it as all the “stuff” that actually does anything. The physical or virtual server resources simply provide the horsepower running the workload.
Common question – what if I have multiple applications? If the multiple applications are all residing on one OS, then it’s simply ONE big workload that looks like this:
OS, APP1, APP2, DATA.
If it’s multiple apps that run on multiple OS, then it’d look like this:
OS, APP1, DATA
OS, APP2, DATA
and thus be TWO workloads.
It’s an industry accepted definition now as well. VMware uses the same term 99% of the time in the same context.
