Mike NormanDr Mike Norman, is the Analyst at The Virtualization Practice for Open Source Cloud Computing. He covers PaaS, IaaS and associated services such as Database as a Service from an open source development and DevOps perspective. He has hands-on experience in many open source cloud technologies, and an extensive background in application lifecycle tooling; automated testing - functional, non-functional and security; digital business and latterly DevOps.

It’s a different way of thinking about the Cloud, where the starting point is not the DataCenter, or the IT service, or the “user”, but the direct delivery of consumer services. Into this vision plays Chromium OS (released to Open Source on November 19th). Google devices delivering Google services (and other services intermediated by Google) from the Cloud to consumers.

Ulteo has just released Version 2 of its Open Virtual Desktop (OVD), an Open Source desktop broker product which is designed to deliver GUI applications running on Linux, Terminal Services and Windows to java-enabled browsers. Ulteo’s appeal is likely to be to more cost-conscious and linux-oriented organizations than the large enterprise customers of Citrix, VMware, Ericom, Systancia or Quest, but within these potentially new markets it can deliver many of the mangeability benefits of the existing proprietary products, and it has few competitors for its key feature of delivering both Linux and Terminal Services desktop applications through the same portal.

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.

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.
