With the release of vSphere 5.0 in 2011, VMware just increased the options for its customers to chose between the traditional vCenter Server which was installed on a 64 bit Windows OS and the freshly baked, Linux Based - vCSA (vCenter Server Appliance).
Though the intention behind this does not look like going away from Microsoft dependency :-) for vCenter. I hear this a lot from a lot of people, however VMware's decision of a Linux based vCenter is more from a customer demand perspective. Customers who are not Windows Centric or in other words are Linux based shops would not want to install a Windows Based Application in there environment as this would increase the cost of acquiring Windows Licenses and most importantly a resource to manage this Windows server.
With this, let's quickly have a look at both the platforms and see which one is the best!!
I would say this is not a fight between which is a better platform, however the decision between selecting the platform depends upon what suits your environment the best.
I hope this will help you take a decision around which option is better suited for your environment.
I would recommend you go through my other articles about vCenter Server which would help you take important decisions around this application which provides you centralized controls and management of your VMware Virtual Infrastructure.
