If Oracle's recent Solaris licensing changes have you singing the blues, OpenSolaris might provide you with a fresh tune to whistle while you work. Last week, the Internet was abuzz with the news that Oracle stopped giving away the Solaris operating system and has now limited the free trial period to 90 days. Now, you must purchase a full license to continue to use the software.
Even if you aren't in one of these affected groups, why not make the switch to OpenSolaris or at least investigate it further? It has all of the Solaris goodness (ZFS, Zones, SVM, and hypervisor-based virtualization) without the licensing restrictions or price of the commercial Solaris offering.
OpenSolaris has much to offer the casual user, the mobile user and the data center. Exploring its extensive list of enterprise features might convince you to rethink its use in your data center.
