The vCenter Server Appliance has come a long way from it’s first iteration way back with vSphere 5.0. A moment of silence for the VCSA 5.0 with embedded DB2 database.
With the vSphere 6.5 release, the vCenter Server Appliance not only gains 100% parity with it’s Windows counterpart, but actually now exceeds it with some exclusive features.
You can interpret the fact that the VCSA is now getting exclusive features however you want to.
Please don’t ask me “Is the Windows vCenter going away?” – because I honestly don’t know the answer.
