The CMDB’s that were designed and architected for static physical systems appear to be unwieldy, too difficult to keep up to date, and not real-time enough to make the transition into the virtualized and cloud based world. Virtualized environment change too fast for existing CMDB’s to keep up, and the notion of keeping a CMDB up to date as assets are moved into and out of public clouds seems hopelessly beyond the intended original use case of a CMDB. A new category of datastore is needed that will address the needs of virtualized and cloud based environments, while incorporating performance information with configuration information.
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.
Cloud Performance Management needs to evolve and allow cloud vendors to provide their customers a customer specific Infrastructure Response Time metric. This in conjunction with cloud aware Applications Performance Management solutions is needed in order for customers to feel comfortable putting business critical applications in the cloud.
Before you all go screaming to your local vendor let me elaborate, the product has just had it’s name changed to reflect a new corporate direction. esXpress is now called PHD Virtual Backup for ESX,
When we put a .NET application on Windows on Hyper-V (or a Java application on Linux on ESXi) we are actually virtualizing twice. Can we virtualize only once, by putting the CLR or the JVM directly on the VM Host? In this action of course we remove the operating system. Oracle is taking the lead in this area with JRockit VE JVM. There is no VMware support, the only hypervisor it supports is Xen, or more precisely Oracle VM. it only comes bundled only with an Application Server, namely Oracle WebLogic Suite Virtualization Option. The entire stack inside the virtual machine is in “User Mode” in other words the JVM and the drivers are all in the same memory address space and you don’t need to switch contexts into Kernel Mode in order to perform I/O or network access. Does VMware have a strategic initiative (or even a skunkworks) to engineer a similar bundle for its SpringSource runtimes? Or are they just concentrating on scaling out with as per the Google announcement?

CA Technologies (CAT) has announced three new virtualization management and performance offerings. This is the first example of a “big 4″ enterprise systems management vendor getting serious about providing virtualization and cloud focused solutions. This will be very reasuring for CAT customers and may will accelerate stalled virtualization projects.
The Red Hat 6 Beta is out, and there is no Xen in it, only KVM. It can operate as a guest in an existing Xen environment, but it cannot act as a Xen host. A few minority interests still cling to Xen, but ultimately it makes no sense for most Linux distributions to ship with Xen. Novell will stick with Xen for a while, and also Oracle, because they are no friend of Red Hat, but when the hypervisor wars become old news, they will quietly move to KVM. It’s easier. In future we fully expect to be talking about Xen/Linux in the past tense.
EMC announced VPLEX at EMC world however, it was hinted at during Getstalt IT’s Tech Field Day at least in its asynchronous mode. What does VPLEX do? What does it mean to the virtualization and cloud industries? These were the discussion within the Blogger’s lounge at EMC World.
Virtualizing Tier 1 business critical applications is a challenge for many enterprises due to the resistance to the concept on the part of applications owners and their constituents. Service Assurance for these applications is required in order for their owners and their users to go along with virtualization. Service Assurance requires the integration of Applications Performance Management, Configuration Management and a new category of solutions like VMTurbo to dynamically allocate resources based upon their highest and best use.
