Welcome to vswitchzero, a personal blog by Mike Da Costa with a primary focus on VMware NSX, VMware vSphere, Cisco routing and switching and PC hardware.

About the Author:

I’ve worked for VMware since 2011 in several capacities but am currently a Staff Escalation Engineer supporting NSX in the Global Support Services organization. In this role, I work with some of VMware’s largest NSX customers and provide backline support on a variety of complex operational and design issues.

Many years ago, I wrote in-depth product reviews for a couple of PC hardware sites. I was always very passionate about technology and enjoyed technical writing. More recently, I did a rotation on VMware’s Knowledge Management team where I wrote and maintained KB articles for VMware. I also had the opportunity to write a few articles for the VMware Support Insider blog, which rekindled my interest in writing again. I’ve started this blog in the hopes that I can share my knowledge and as an outlet to discuss the things that interest me.
