vRealize Automation Capsule


Okay, so recently I have had the chance to play around with vRealize Automation (vRA). Therefore, I am using this chance to share with you the outcomes of this interesting endeavor of mine.

What is NSX?

NSX is VMWare virtual networking on steroids.

There are several components that constitute the NSX Architecture. The reason why I believe that NSX is a true Software Defined architecture is the clean decoupling and separation of its components.
