Hopefully you have heard about the Oracle Solaris 11.3 Beta release but if not you can learn more here.
One of the key features of the Oracle Solaris 11.3 Beta release is the introduction of Secure Live Migration for Kernel Zones. This feature brings with it a couple of things of note.
First the obvious part - with live migration system administrators can limit the number and types of outages to applications and end users. This is particularly useful when there is a requirement to do system maintenance to the underlying OS or hardware. The Kernel Zones environments can be migrated off the source system before this maintenance. This is especially useful in today's datacenter where workloads (and owners of those workloads) running on systems can be many and varied. It is not always simple to organise a common outage window and can actually be quite frustrating.
Secondly the secure part. With secure live migration, not only is your data protected but man in the middle attacks are prevented. As with other security features in Oracle Solaris this is the default setting and automatically takes advantage of the available hardware crypto accelerators - meaning you get this protection at no additional performance cost. You may have to set up some security keys but our documentation walks you through this.
