The Virtualization Practice

Data Center Virtualization

Data Center Virtualization covers virtualizing servers, networks, and storage delivering server consolidation, CAPEX savings, IT agility, and improved management. Major areas of focus include the tradeoffs between various virtualization platforms (VMware vSphere, Microsoft Hyper-V and Red Hat KVM), the evolution of hypervisors into data center management platforms, ...
VMware’s Software Defined Data Center strategy, and how the SDDC is spurring innovation in storage, networking and server hardware. Covered vendors indlude VMware, Microsoft, Red Hat, CloudPhysics, Hotlink, Tintri, and VMTurbo.

Just as Milton Friedman (the Nobel prize winning economist) once said “There is no such thing as a free lunch”, there is also no such thing as free software. The minimum cost of a supposedly free piece of software is the opportunity cost of your time spent using it, and the forgone value of that time spent doing something else. Therefore neither Microsoft Hyper-V, nor VMware ESXi are really free.

VMware Study – Benefits of Virtualization for the SMB

VMware has recently released the results of a new study that VMware did of 309 companies that have between 20 and 1000 employees. The two major benefits of virtualization reported by the survey participants were reduced time spent on routine and repetitive tasks, and improved applications availability. 73% of respondents reported reductions in time spent on routine tasks, and 71% reported improvements in applications availability.

I recently participated in the InformationWeek Dark Security Virtual Event as a panel member with Hoff, Craig Balding, Chris Wolf, Glenn Brunette, and Jon Oberheide. A very far ranging group of individuals from research, security organizations, analysts, and authors. What is interesting is that most of these same people have joined me on the Virtualization Security Podcast, and the others I hope to have as guests next year. There was one question that set me to thinking even more, do we need a new way of thinking about virtualization security?

Applications Performance Management Vendors – Cross Platform Support

2010 will be the year that many enterprises confront two very important changes to how they will use server virtualization. The first change is that as VMware vSphere has proven its maturity, performance and scalability enterprises will increasingly put business critical tier applications, at least in part on virtualized platforms. The second change is that at the same time, these very same enterprises will start to evaluate virtualization platforms from other vendors, in particular Hyper-V from Microsoft.

75% of users report using VMWare today, and nearly 2/3rds report having tested an alternative hypervisor with Microsoft Hyper-v and Citrix Xen most often mentioned. Of those who have tested an alternative, 27% plan to use the it, while an additional 20% report that they may use it. Only 2% of VMware customers plan to switch to an alternative additional 9% considering it.

Virtualization Management – Hyper-V Support is Gaining Momentum

The support for multiple virtualization platforms on the part of these third party virtualization managements vendors also raises an issue and an opportunity for enterprises with large scale VMware deployments. The issue is to determine if the enterprise is going to end up with more than one hypervisor. If the answer is yes, then the opportunity is to look at a virtualization management solution from a vendor like Dynamic Ops, Fortisphere, ManageIQ, Platform Computing, Surgient, or VizionCore.

With the announcement of V-Block and Cisco UCS as a major component, is more hypervisor functionality going to end up in hardware? UCS adds some interesting features into the hardware that were traditionally within the purview of the hypervisor. Now it looks like V-Block is the assembly of myriad components that taken as a whole look remarkably like the beginnings of a hardware based hypervisor.
