Is Solaris shining in the enterprise sector again?

Oracle is touting a resurgence in Solaris on SPARC sales today. But is the venerable Unix platform making a comeback, or are there are other market forces at work?

While Linux has strongly dominated the enterprise server space for many years, there have always been other Unix-family operating systems as outliers in this sector: Oracle’s Solaris, Hewlett Packard’s HP-UX, IBM’s AIX, and a whole raft of worthy BSDs have filled many slots in IT data centers.
