Long a leading advocate of “thin client” computing, largely as a way for Sun to compete against
Microsoft’s greater strength on the desktop, Sun is a natural to back virtual servers. It has built virtualization into its
servers and supported VMware and other virtualization vendors without making a point (as it often did in the past) of
trash-talking Microsoft to polarize a competition in which both are chasing relative upstart VMware.
As the leading (debatably the only) pure Unix vendor among major industry players, Sun is in a position
even more clearly neutral than Novell, and is taking advantage of it. It has supported VMware almost from the beginning and
has sold its Solaris operating systems with both hypervisors and virtualization-management products. It has also built a
significant integration-and-support business to help end users migrate.
