License change leaves Sun Solaris users at a crossroads

Filed under

Recent changes to Solaris licensing could further encourage Solaris 10 users to consider Linux -- and result in fewer new users considering Solaris at all. If you're a Solaris customer, don't overlook this license change.

While the "Linux versus Windows" competition is often played up in the press, the reality is that Linux workload overwhelmingly comes from Unix migrations. Being the largest Unix platform, Sun Solaris has faced stiff competition for lower-end workloads against Linux for the better part of a decade. As Linux usage and features have grown, so too has the applicability of Linux in more mission-critical distributed environments, an area historically associated with Unix and Sun Solaris. Sun tried to slow, and even reverse, this trend in 2005 by offering Sun Solaris 10 free of charge. To make money, Sun expected to sell subscriptions to customers seeking support and defect fixes.
