Bernd HarzogBernd Harzog is the Analyst at The Virtualization Practice for Performance and Capacity Management and IT as a Service (Private Cloud). Bernd is also the CEO and founder of APM Experts a company that provides strategic marketing services to vendors in the virtualization performance management, and application performance management markets. Prior to these two companies, Bernd was the CEO of RTO Software, the VP Products at Netuitive, a General Manager at Xcellenet, and Research Director for Systems Software at Gartner Group. Bernd has an MBA in Marketing from the University of Chicago.

There are some applications that are “never” going to go into a public cloud and the monitoring of those applications is not going to be done on a MaaS basis either. However, the ease with which these solutions can be purchased, initially deployed and then managed on an ongoing basis means that for applications that fit into a public cloud deployment scenario (you can live with the security and performance issues of the public cloud), MaaS is a very viable option for the monitoring of these applications and may represent the future of monitoring just as Cloud Computing may represent the future of computing.

Virtualization Performance and Capacity Management spans Configuration Management, Resource and Availability Management, Infrastructure Performance Management, Applications Performance Management, and Service Assurance. A broad range of solutions in these areas exist from third party vendors as well as from virtualization platform vendors like VMware. Correctly choosing these solutions is essential for organizations that wish to virtualize business critical applications and guarantee the performance of both the virtual infrastructure and the applications.

The combination of Quest, Vizioncore and Surgient creates a company that for the first time has all of the management pieces required for an enterprise to be able to virtualize tier one applications and to automate the process of assuring service levels for these applications. This puts Quest in position to be a clear leader in the virtualization management market.

Who’s Who in Virtualization Management

Virtualizing business critical systems requires that a layer of virtualization management solutions be added to the virtualization platform. Virtualization management solutions in the areas of virtualization security, virtualization configuration management, virtualization service and capacity management, virtualization service and capacity management, virtualization provisioning and lifecycle management and backup and recovery should be added to the platform.

Virtualizing Business Critical Applications – A Reference Architecture

Virtualization Security, Configuration Management, Service and Capacity Management, Provisioning and Lifecycle Management, and Backup/Recovery are essential functions that must be added to a virtualization platform when virtualizing business critical applications. VMware vSphere is clearly the market leading and most robust virtualization platform – and clearly the virtualization platform most suitable as the foundation of a virtualization system designed to support business critical applications. However, the virtualization platform must be complemented with third party solutions in these areas in order to create a system that can truly support business critical applications in an effective manner.

Cloud and hosting providers are aggressively investing in new Intel Xeon servers that can have as many as 32 cores per server (4 processors with 8 cores per server). Some of this investment is in response to current demand for actual capacity from customers. Some of it is investing ahead of the curve so that the cloud vendor is properly positioned when the demand arrives. The growth and the hype in the cloud is such that there is highly likely to be an overbuild of capacity at some point and then a crash and a period of consolidation – just as there was with ASP’s and the .com companies.

The ROI for Server Virtualization with Business Critical Applications

The ROI from virtualizing tactical applications is driving by the consolidation in the number of physical servers needed once tactical workloads are virtualized. However, when virtualizing Tier 1 or business critical applications, it is likely that significant consolidation in the number of cores per workload is not possible – leading to the requirement to find a new way to cost justify these projects.

vSphere 4.1 Released – More Dynamic Resource Load Balancing

With the release of vSphere 4.1, VMware has added to their Dynamic Resource Load Balancing (DRLB) suite of tools that I hinted at in my post on Dynamic Resource Load Balancing that I wrote last week as well as providing new memory over commit and other functionality. In essence, vSphere 4.1 is more than a point release, this update includes many features that aid in security, reliability, and is a direct response to customer requests.
