Oracle VP Makes Shocking Revelation!: Xen Bits Actually *are* in Linux!

For those of you that relish a bit of technology deep-dive now and again, I've got a great entry for you from the Senior Vice President of Virtualization and Linux Development and Support at Oracle Wim Coekaerts (...and Linux Foundation board member.  And my boss.  Yes- that's his picture and, no, he doesn't have that beard anymore.  Well, not most days.)  It's about how, despite what you may have heard in the past, the bits that optimize Linux for running in Xen environments actually *are* now in mainline Linux.  Xen is alive and well, thank you and there are darn good reasons for that.

Perhaps one of the things we in the Xen community have not talked about loud enough and consistently enough is how Xen absolutely dominates public cloud infrastructures, including the biggest of them all Amazon, who use not only open source Xen but also Oracle VM (based on Xen) to underpin their Amazon Web Services EC2 offering.   For those of you contemplating implementing your own internal cloud fashioned on the model that has been so successful for the leaders in cloud computing, i.e. the public cloud guys, think long and hard about that:  why have nearly all the big and emerging cloud players chosen Xen?   Xen is here, it is a vibrant community, and it is a proven, robust technology that is more than ready for the enterprise as well.  And adoption of the various Xen optimizing kernel bits into the Linux mainline shows that it will continue to be maintained and enhanced for a long time to come, so don't let anyone tell you otherwise.

For the full story in glorious, geeky details, take a look at Wim's blog entry.
