Moving to the cloud! Let me be a little more precise and say moving to the public cloud. This concept has really been embraced and thrives in the consumer area but will this concept really take off in the corporate world and really should it? One of the main concepts of virtualization, in the beginning, was the ability to consolidate physical systems into a virtual environment to shrink the overall foot print size as well as being able to take advantage and use all available compute resources available in a physical server and having centralized control of the compute, storage and networking resources.
When it comes to public cloud computing services that old adage of “fast, cheap, or good – pick any two” certainly hold true. Amazon can offer you cheap, and since they own their stack, a rapid cycle time DevOps approach to support. But you are not going to get enterprise grade service level guarantees for Amazon’s pricing. To get both agile responsiveness and enterprise grade SLA’s you are going to have to give up on cheap.
Open Source continues to be an important part of the mix in Virtualization and Cloud. Indeed, this year has seen major developments in established players at the Operating System and Hypervisor level, as well as a major new cloud entry at the IaaS cloud layer.
During the Virtual Thoughts podcast on 6/29/2010, the analysts discussed various hardware aspects of virtualization trying to determine if the hypervisor was to move into the hardware? and if so how much of it? as well as whose hypervisor? and lastly such a move part of any business model?
Virtual Thoughts is a monthly podcast that looks at the entire scope of virtualization to discuss new trends and thoughts within the virtualization and cloud communities.
This weeks podcast started with a discussion of TPM/TXT and the boost it gives to virtualization security. Since TPM/TXT is based in the hardware and provides a measured launch of an operating system, the next logical discussion was on whether or not the hypervisor would be placed into the hardware?
As of Service Pack 1, SUSE Linux Enterprise Server 11 (SLES) supports KVM for SUSE guests. This post follows on from our previous post regarding the demise of Xen in Red Hat Enterprise Linux, and perhaps suggests the beginning of the end for Xen-based virtualization in Linux, but the story is far from clear. A complex set of agreements with Microsoft mean that Novell is bound to preferentially support Windows guests, and it may be a while before KVM support is adequate, although Novell has a project called Alacrity to help get it there. In the meanwhile Novell may get split up into pieces by a private equity house and SLES find itself a new owner.
PhD Virtual has gained its second round of funding with investment from Citrix amongst others as discussed within our post News: esXpress is no more but what does this mean for XenServer? Up until this point it looked like Citrix was out of the server hypervisor wars and backing Microsoft’s Hyper-V play. Yet this looks on the surface like a basic shift to that direction. Yes, XenServer was placed into the OpenSource community and the latest improvements, such as the Open VSwitch integration and a new releases emphatically say that XenServer is alive and well and that its ecosystem is growing for that matter so is Hyper-V’s.
