VMware vSphere 6: Hidden C# client enhancement

I have seen multiple vSphere environments in the last couple of months, which had a lower EVC baseline as necessary configured with vSphere 5.5.

Like in all design considerations the only “correct” global answer is “It depends!” 🙂 A colleague asked me last week, if it wouldn´t be more secure to run vCenter beside the ESXi hosts on […]
