The Virtualization Practice

Virtualization Management

Virtualization Management covers all aspects of managing a modern virtual or software defined data center. This includes managing across virtualization platforms and clouds, monitoring the performance and availability of the virtualization platforms (hypervisors) and the clouds, monitoring the capacity of the virtualization platforms and clouds, ...
monitoring the performance of the applications running on these platforms and clouds, automatically provisioning these environments, securing these environments, and ensuring that the data in these environments is always protected and available.

Applications Performance Equals Response Time, not Resource Utilization

Transaction rate, an average response time goal, and an allowable upper bound, combined with transaction rate will come to define performance and capacity. These new metrics will get monetized allowing applications owners to shop for price/performance curves across internal and external service providers on a rational and economic basis.

Virtual Computer are to optimize their NxTop client virtualization and management solution to operate with select models of Lenovo laptops and desktops PC platforms. For their part, Lenovo will allow customers to have Virtual Computer’s NxTop client loaded onto their custom images, direct from the factory. There are a number of client hypervisor solutions that can be used by enterprises today. The focus for these have been on security. At moment, the only vendor offering an enterprise ready PC management solution based on client hypervisor is Virtual Computer. The partnership withLenovo is likely first in line of tie-ups. Nxtop is Enterprise ready, with such deals Enterprises will be better ready for NxTop.

Constructing a Best of Breed Alternative to VMware vCenter Operations Enterprise

With VMware vCenter OPS, VMware has stated that performance, capacity, and configuration data need to be integrated into a self-learning model in order to monitor a dynamic system. This model can be implemented as well using third party solutions like those from Quest, CA Technologies, AppDynamics, Bluestripe, dynaTrace, VKernel, NetApp, Netuitive, Net Relic, Coradiant, VMTurbo, Xangati, and Zenoss.

Virtualization Performance and Availability Monitoring – A Reference Architecture

In “A Perfect Storm in Availability and Performance Monitoring“, we proposed that legacy products from the physical environment should not be brought over into your new virtualized environment and that you should in fact start over with a horizontally layered approach, choosing a scaled out, and highly flexible product that can integrate with products at…

The right approach to monitoring a virtual or cloud based environment is to start with a clean sheet of paper, determine your requirements, and assemble a horizontally layered solution out of best of class vendor solutions that address each layer. Vendors should be evaluated on their mastery of one or more layers, their ability to keep up with the change in that layer, and their ability to integrate with adjacent layers.

In my last post I was Exploring a Limitation of VMware DRS and I have encountered another situation that had similar symptoms but the resolution was quite different. This problem was occurring on a VMware ESX 3.5 cluster that was specifically affecting Windows 2008 R2 64bit virtual machines that were configured with four processors and eight gigabits of RAM. These virtual machines were taking an extreme amount of time to perform a reboot. During the reboot ESXTOP was showing insane %RDY with spikes climbing over 200. When the reboot would finally finish several services would have failed to start.

While we may well be on the road towards VMware becoming the layer of software that talks to the hardware in the data center – removing Microsoft from that role, this is not the end of Windows. If Windows were just an OS, it would be severely threatened VMware insertion into the data center stack. But Windows is not just an OS. Windows is also a market leading applications platform with .NET have a far greater market share and base of developers than vFabric. Windows is also in the process of becoming a PaaS cloud – one that will be living at Microsoft, at thousands of hosting providers, and at probably every enterprise that is a significant Microsoft customer. This incarnation of Windows is at the beginning of its life, not the end.
