Public Cloud Reality: Do we Stay or Do We Go?

CloudComputingSoon the backup power will be available for our new datacenter and the redesign to make use of VMware vCloud Suite is nearing completion. Soon, our full private cloud will be ready for our existing workloads. These workloads however now run within a XenServer based public cloud.  So the question is, do we stay in a poorly performing public cloud (mentioned in our Public Cloud Reality series) or move back to our own private cloud? As the Clash put it “Should I Stay or Should I Go Now.” Continue reading Public Cloud Reality: Do we Stay or Do We Go?

Hotlink’s Cross-Platform Management Technology

DataCenterVirtualizationOne of the companies and technologies to watch is Hotlink with its Cross-Platform Management Technology (winner of Best of Show, VMworld 2012). If you have not heard of this before, I think you will in the near future. This technology allows you to use VMware’s vCenter Server to manage and control all major hypervisors and public clouds to include VMware vSphere, Microsoft Hyper-V, Citrix XenServer, Red Hat Enterprise Linux (KVM), CloudStack, and Amazon EC2, all from within VMware vCenter.

Replacing DRS – With What and Why?

DRS is one of the most useful and interesting features of VMware vSphere (to be more specific – feature of versions of vSphere from Enterprise on up). DRS is useful because it prevents workloads (VM’s) that are consuming more than the expected amount of resources, from potentially harming the performance of their neighbors in the same host with this “excess” resource consumption. DRS is interesting because the idea of dynamically balancing the load of a system in order to ensure the performance of the critical workloads running on that system is something that was taken for granted in the days of the mainframe, but has not as yet been well implemented on distributed Intel architecture systems.

Virtualizing Business Critical Applications – A Reference Architecture

In The ROI for Server Virtualization with Business Critical Applications, we showed an example of how the savings from server (specifically core) consolidation might not be as large when one is virtualizing business critical applications (where the physical servers were appropriately sized in the first place) is it is with tactical applications (where the one server per application resulted in massive over-provisioning). At the end of that analysis we also pointed out that the business critical case did not include the other “extra” products that would need to be a part of a business critical application virtualization project. This post proposes a reference architecture for the entire suite of solutions that will be required to virtualize business critical applications. We are going to build this example around VMware vSphere as VMware has the broadest level of third party support in terms of vendors who provide the solutions required to fulfill the requirements of the reference architecture.

VMware vSphere Security Guidance, just the Beginning

On the most recent Virtualization Security Podcast, the panel was joined by VMware’s Charu Chaubal to discuss the latest draft of the VMware vSphere hardening guide. Of note during the conversation was the new layout and scope of the guide which is now split into the following sections:

VMware and Microsoft Race to Make Each Other Irrelevant

One of the time honored strategies in the computer industry is to package your competitor out of business. Vendor A thinks that they have a robust standalone product business, and Vendor B makes Vendor A’s product into a feature of a larger product and Vendor A goes away. There are many examples of this. Microsoft started this game by combining Word, Excel and PowerPoint into a Suite, putting the then incumbent leaders (Lotus, WordPerfect and Harvard Graphics) under severe pressure. Years later Microsoft did this same thing to Novel by packing Network Operating System functionality into Windows, and then a few years after that did it again to Netscape by packaging the browser into Windows.

Now both Microsoft and VMware are trying to do this to each other, but in more sophisticated and insidious ways than has ever been attempted before. The reason for all of the sophistication is that this is quite literally a war of extinction where the loser may end up going away. Let’s take a look at the two strategies.  Continue reading VMware and Microsoft Race to Make Each Other Irrelevant
