Citrix Aims for the Competition With XenServer 6
Citrix's XenServer server virtualization technology doesn't have a huge market share. But that's not to say its insignificant: It has its followers--especially those looking to virtualize Linux workloads--and it has its place, often as a secondary platform for companies using VMware or, increasingly, Hyper-V.
When Citrix announces a major release, as it did last Friday with XenServer 6, it's definitely worth taking a look to see what's new. But first, let's take a look at how Citrix is selling the product, because the way a company does that can be very telling.
One key point Citrix would like you to know is that XenServer 6 is optimized for cloud computing and the "Cloud Era." In fact, the cloud computing message is threaded throughout Citrix's announcement, along with reminders that you can use XenServer 6 with Citrix's CloudStack cloud platform. Citrix acquired CloudStack when it bought Cloud.com in July. Because of that, the company decided to pull the Self-Service Manager feature, which was present in the beta version of XenServer from XenServer 6. Right now, CloudStack is great for public cloud service providers or Web 2.0 application companies, but it is not suitable for enterprises that want to run a private cloud in-house in their data center, according to Derek Slayton, Citrix's senior director of product marketing for XenServer. Apparently, the Cloud Era doesn't include private clouds, then. That's, ahem, surprising.
I think it's time to try something else besides, Virtual Box and Qemu...
