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.

IBM has reduced the price of its Mainframe/Linux platform, providing an IBM price point and feature benchmark against which to compare the consolidated offerings which are starting to emerge from competing vendors, such as the Acadia group (Cisco, EMC, or VMware) and HP/Microsoft.
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 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.
In the long term, 2009 is likely to be known as the year that a commercial framework emerged around the Open source Hadoop framework for map-reduce.
Which is better Hyper-V version deploy for production environments? For a traditional server based virtualization project, it makes financial sense to deploy Datacenter, and this is most likely the case for a hybrid deployment of Server and Desktop devices. However, for raw VDI and Open source deployments, it is obviously more fiscally prudent to utilise the free version which has been available for over a year.

Citrix have released an updated version 2 of their Receiver for the iPhone, but if they are to keep ahead of the competition, is delivering VDI access to the all powerful iPhone the best device to grab a CIO’s attention with?
In the article End-to-End Virtual Machine Backup I mentioned the new VMware Workstation 7.0 feature that creates an encrypted disk but in reality it is an encrypted virtual machine, which also implies encrypting the virtual disk. This one option to VMware Workstation is something that is needed within VMware vSphere as well as the other hypervisors. Encrypting virtual disk data can add to the overall security stance based on the encryption technology employed. So what do we need with virtual disk encryption?
As of the end of last year, there are a new breed of virtualization backup tools (Veeam, vRangerPro, esXpress) now available, end-to-end backup tools (Acronis, Symantec). These tools will backup a virtual machine to tape using built in mechanisms instead of requiring scripting, or multiple backup tools. The question is: is this necessary? Should virtual machine backups be dropped to tape at all? Something to watch through out the year.
