Simon Crosby von Citrix hat in seinem Blog Stellung auf einen Beitrag von Brian Madden zu einem möglichen Ende von Xen genommen. Nach der Einführung von Hyper-V durch Microsoft könnte Citrix Xen fallen lassen und sich auf Hyper-V konzentrieren (“When Hyper-V comes out, Citrix will shift focus there, away from Xen”).

Simon Crosby hat nun mit einem Beitrag “Xen is Dead! Long Live Xen!” die Virtualisierungsstrategie von Citrix noch einmal untermauert und kommt zu vier Kernpunkten:

1. XenServer is growing strongly on its own, and XenServer is inside the industry’s most differentiated enterprise virtual infrastructure products from leading vendors.  It offers the greatest price performance, compatibility with Hyper-V, and a rich ecosystem of customer-focused value props for management, availability, dynamism and flexibility.  Get it in your next server, completely built in.
2. VMware has a strong lead, customer confidence, significant presence, and expensive, over priced products that demand customers buy into a single vendor, proprietary, closed, monolithic architecture that has significant architectural and scalability drawbacks.  Next time your VMware sales guy calls, ask him for some of the free stuff, or better, just download XenServer for free.
3. Microsoft Hyper-V is a fine implementation of the Xen architecture, compatible with XenServer.  It has a strong development plan.   XenServer today and in the future will extend Hyper-V to address advanced use cases, and to support specific Citrix/Microsoft product partnerships.  A good example is XenDesktop.  There will be others.  System Center VMM is a great product, and will be able to manage XenServer as well as Hyper-V and VMware.
4. The Xen community is vibrant and growing.   Xen is widely used, massively deployed, core to the product and corporate strategies of some of the industry’s largest vendors.  Predicting its demise would be extremely naïve.  KVM is very “in”:  interesting, incompatible and incomplete.  The two projects can co-exist independently and happily.
