The Virtualization Practice

Data Center Virtualization

Data Center Virtualization covers virtualizing servers, networks, and storage delivering server consolidation, CAPEX savings, IT agility, and improved management. Major areas of focus include the tradeoffs between various virtualization platforms (VMware vSphere, Microsoft Hyper-V and Red Hat KVM), the evolution of hypervisors into data center management platforms, ...
VMware’s Software Defined Data Center strategy, and how the SDDC is spurring innovation in storage, networking and server hardware. Covered vendors indlude VMware, Microsoft, Red Hat, CloudPhysics, Hotlink, Tintri, and VMTurbo.

Citrix has recently joined the Linux Foundation, and there is a report (which they seem to have endorsed) that they plan to open source XenServer. That’s not Xen, it’s XenServer – not the kernel, the product, the thing you stick on your server instead of ESXi, or sometimes vSphere.

It is entirely possible that Citrix’s lawyers have noticed that XenServer was so infected with GPL code that it was already Open Source anyway.

During Gartner Symposium/ITxpo outlook for the server virtualization market, Gartner dropped two very interesting numbers on the audience. The first was that only 16% of the workloads worldwide are running in virtual machines today. This is a far lower number than has been suggested by any number of other sources. Gartner went on to predict…

There’s been a lot of press around the FREE Ubuntu 9.10 Linux distribution as a client operating system, and a wide set of comparisons made (typically by Mac or PC-using journalists) between Ubuntu and Windows 7, but 9.10 is also interesting from a broader virtualization and especially Cloud perspective. Ubuntu is managed by a UK company, Canonical, through a bona-fide foundation. Ubuntu will always be free, and is aligned with the Debian community.

Microsoft and Red Hat Cross-Certify to try and get VmWare out of the Datacenter. Red Hat Enterprise Linux 5.2, 5.3, 5.4 has passed certification tests when running on Windows Server 2008 Hyper-V, Microsoft Hyper-V Server 2008 and Windows Server 2008 R2 Hyper-V, Microsoft Hyper-V Server 2008 R2.
Windows Server 2003/ Windows Server 2008 / Windows Server 2008 R2 are validated to run on RHEL 5.4, using the KVM-based hypervisor.

Virtualization – A Feature of the OS, or a New Platform?

Microsoft and Red Hat has just announced that they have completed the certifications of the cross OS hypervisor agreements that the companies originally announced back in February of 2009. This means that Microsoft now certifies Red Hat Linux guests on Hyper-V and Red Hat certifies certain Windows guests on KVM. Red Hat has an excellent article on its web site that details which version of which products work with which and which provides an excellent FAQ.

Eucalyptus is a software stack that when added to a standard virtualized data-center or co-located server network, turns it into a Cloud which looks exactly like the Amazon Elastic Compute Cloud (EC2). It is a “self-build” Amazon Cloud kit. Just add hypervisor.

We consider Eucalyptus in the context of cloud to datacenter migrations, and standards for cloud APIs.
