Capacity Planning and Capacity Management are essential activities for any production virtualization deployment, and should be supported with appropriate tools that support the target hypervisor(s). However, the emerging need in this area is for true Infrastructure Performance Management – as these solutions give the IT Operations staff the information that they need to be able to confidently support Tier 1 applications in production – while being able to demonstrate the performance of the virtualized system to the applications owners and business constituencies.

Is Virtualization Solutions Delivery Fundamentally Changing?

It is clear that once virtualization started delivering hard dollar CAPEX and OPEX savings to IT executives that these executives wanted this trend of “more for less” to continue. Most IT organizations are far from 100% virtualized, and there are still substantial cost savings to be gained from further virtualization. However, forward thinking vendors (like Cisco, EMC, and HP) see the handwriting the wall and are taking steps now to be able to deliver solutions at reduced costs to their customers.

Virtualization Splits Up the Performance Management Business

Virtualization has been a catalyst for significant changes in the performance management business at all layers of the IT stack (from hardware to transaction). These changes have only begun. As the more and more tier 1 applications get migrated over to a virtual infrastructure, these vendors will advance their functionality, and more vendors will jump into the fray. It is also highly likely that over the next 24 months, the larger traditional vendors (HP, IBM, BMC) will get more active in this space – driven primarily by the fact that CA has now gotten active via its acquisition of NetQos.

VMware Buys Zimbra from Yahoo – Moves Up the Stack into Applications

If VMware buys Zimbra it will set off a a nuclear hand grenade throwing contest between Microsoft and VMware. Microsoft is trying to commoditize the layer of software where VMware makes all of its money – the hypervisor. VMware is returning the favor by using open source initiatives like SpringSource and (possibly) Zimbra to commoditize the layers where Microsoft makes all of its money – applications and applications platforms.

VMware is today a product, the start of an architecture and almost certainly a culture. How this changes as VMware adapts in order to continue to grow and drive its market share will be interesting to watch. A great deal of very technically competent people have become part of the VMware ecosystem because VMware is both difficult t to fully master completely and because it drives great benefits to the enterprises that adopt it and the service providers that implement it.

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.

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.
