Sun Solaris 10
For Sun customers, upgrading to Solaris 10 is very much a 'no-brainer', and for several very good reasons. To start with, it's faster than any previous Solaris implementation, with a slick new IP stack just one of many performance enhancements. Plus it’s a lot more secure, featuring a new integrated cryptographic framework based on the Trusted Solaris product. The Role Based Access Control (RBAC) technology, introduced a couple of releases back, has also been extended to give fine-grained control over both users and processes, while applications and services can now be isolated within their own virtual execution space using Solaris Containers (formerly N1 Grid Containers).
