The name "ESX" has been associated with VMware's virtualization platform, evolving from VMware ESX Server to VMware ESXi. Initially, it was known as VMware ESX Server, with the "ESX" standing for "Elastic Sky X". Over time, the product shifted to ESXi, which dropped the "X" and represented a more streamlined, service console-less design.
