VMware WorkstationA powerful desktop machine for technical work — between personal computers and minicomputers in price and capability. brought practical x86Intel's dominant CPU architecture family — the instruction set behind most PCs and servers for decades. virtualization to developer desktops.

It made cross-platform testing and server simulation routine before cloud VMs were ubiquitous.
