Have you ever considered the best way to plan, design and work with VMware Update Manager (VUM)? In the early days using VMware 3.x when VUM was first released, I would end up installing VUM on the vCenter server itself. After all, that was the recommendation from VMware at the time. I propose that this is no longer the case and I would like to present a list of best practices to follow when working with VMware Update Manager. This list came from VMware, but should only be considered as a guide. Each environment is different and your mileage may / will vary.
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.

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.

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.

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.
I just finished writing all the content for my next book entitled VMware ESX and ESXi in the Enterprise: Planning Deployment of Virtualization Servers (2nd Edition) which continues the discussion on Dynamic Resource Load Balancing (DRLB). DRLB is the balancing of virtualized workloads across all hosts within a cluster of virtualization hosts without human intervention. This is the ultimate goal of automation with respect to virtualization and therefore the cloud. In effect, with DRLB the virtualization administrators job has been simplified to configuration and trouble shooting leaving the virtual environment to load balance work loads on its own.

Microsoft is bringing its strongest assets – the installed base of its key products in the enterprise, and its library of commercial and custom built applications (and their associated developer communities) along with compelling new technologies like Server App-V to the virtualization and cloud fight. Leveraging Azure and App-V along with these existing enterprise assets makes Microsoft into a much more potentially formidable competitor to VMware than Microsoft is today based solely upon Hyper-V.

Supporting Tier 1 applications on VMware vSphere requires real time and granular response time and latency instrumentation of the virtual and physical infrastructure. Virtual Instruments Virtual Wisdom complements the instrumentation provided by VMware by providing individual transaction level visibility into the SAN layer of the virtual infrastructure.
