Solaris 10 no longer a free offering
Oracle is the new owner of Sun Microsystems and they have already started making changes which is not going to make them popular in the market.
The company has changed the license of Solaris 10. It is no longer available as a free product. Though users can get a 90 day trial.
After the 90 day period is over, users would have to purchase a service contract in order to use the software.
OpenSolaris is however safe for now. It remains under an open source license and can be downloaded and used for free.
However, analysts believe that Oracle would not provide major updates to OpenSolaris platform to ensure that Solaris remains the best offering that comes with a price.
