I am a system integrator and have experience with many different IT products. I regularly work with a lot of different technologies. Recently, I have been working on configuring VMware and virtualization. For example, I am considering upgrading the ESXi.
We run VMware Workstation locally. You can run it on AWS but that's not necessary for what we're doing. There are use cases where it will be applicable but I'm dealing with a construction company, as opposed to a heavily vested IT company. The use cases are quite a bit more laid back.
We primarily use it for virtualization. We image older systems, so we have a backup copy that's immediately accessible. Those are the major use cases.
