VMware long-timer Brian Byun leaves the company

Brian Byun, who helped guide VMware’s move  into mobility and desktop computing (i.e. beyond server virtualization) has left the company and is on sabbatical, according to his LinkedIn profile. 

Most recently, Byun who joined VMware(S vmw) in 2003, was VP and GM of End User Computing (EUC). At one point during his tenure he  headed up all products before moving into the company’s desktop and mobility effort to push beyond its server virtualization roots.

Given that many of VMware’s desktop and application-oriented acquisitions — SlideRocket, Zimbra —  have been sold off in the last few months — Byun’s exit may not be a huge surprise. In addition,  VMware brought in former SAP mobility exec Sanjay Poonen  as GM for the end-user computing effort in August.

According to Byun’s  LinkedIn(s linkd) blurb, he will advise companies wanting expertise in consumer/mobile IT; modern cloud and application platforms, and the “SaaSification and de-perimeterization” of the enterprise.

Neither Byun nor VMware could be reached for comment.
