Public Cloud Computing – Economics and Throats to Choke

When enterprises consider putting business-critical workloads in public clouds, many of them overlook, at least in part, critical issues of economics and over what portion of their cloud software stack the cloud vendor has full control. This leads to a situation where sometimes relatively inexpensive offerings where the vendor has full control of their software stack (like Amazon EC2) are improperly compared to an offering from a vendor like Savvis or Terramark who is building a cloud out of either VMware-provided components or OpenStack components. This gives rise to important issues that drive both the cost of the respective offerings and the degree to which the cloud vendor can both enhance the offerings with rapid agility and quickly address service level issues.

Open Source Year in Review

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.

Virtual Thoughts: Is the Hypervisor moving into Hardware?

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.

KVM in SUSE, what is going on at Novell?

As of Service Pack 1,  SUSE Linux Enterprise Server 11 (SLES) supports KVM. The bald facts are as follows.  SLES 11 SP1 is based on a 2.6.32 kernel and is now full supported on x86_64 processors which support hardware virtualization, for the following guest operating systems:

  • SUSE Linux Enterprise Server 11 SP1
  • SUSE Linux Enterprise Server 10 SP3
  • SUSE Linux Enterprise Server 9 SP4

We note there is no mention of other Linux guests or Windows 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.

Growth of Citrix and Hyper-V EcoSystems

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.

There are now many more products on the market that not only cater to VMware but Hyper-V and Citrix XenServer, Xen, and with that KVM. Some of these tools are well known in the virtualization community while others are not. This is a list of tools that have specific code and integrations for each of the listed hypervisors, not ones that naturally work with all hypervisors such as many APM and other Performance Management solutions, that is a different type of list.

VMware – Product, Architecture, or Culture?

As the year draws to a close the tendency is to both reflect upon the past and to try to anticipate what the next year is to bring. Thinking about our industry (Virtualization and Cloud Computing) in this way raises some interesting questions that are worth exploring.

Is VMware a Product?

This question more fully stated really means is VMware vSphere really over the long term a product which currently leads a new category of products, or is it destined to become a feature of some broader and more established offering? If we look back over the last few years, it is clear that VMware ESX and now vSphere have established the start of a new product category. Other products in this category include Microsoft Hyper-V, Citrix Xen, Red Hat KVM, and if one goes outside of x86 virtualization, IBM Power VM.
