Virtualization Aware APM Advances

We categorize the vendors that do performance and availability monitoring for virtualization and cloud computing into four categories: Resource and Availability Monitoring – This is primarily about taking data from the hypervisor vendor (most often the VMware vCenter API data), storing it, trending it, reporting on it, analyzing it, and alerting on it. Infrastructure Performance…

VMware has acquired the Virtual Profiles, Pinpoint, and Discover assets of RTO Software. This will raise the bar on the other vendors of desktop virtualization platforms (Microsoft and Citrix), but will also leave room for more granular User Environement Management approaches from vendors like RES Software, LiquidWare Labs, Tricerat, and when they ship – UniDesk.

The grid approach to desktop virtualization, offered by vendors like Kaviza and Synchron offers several advantages in terms of cost and flexible use of hardware resources. The cost savings come from not requiring a SAN. The implications of no SAN are no VMotion, no HA and no DRS. However Citrix XenApp has proven that user and application centralization can be effectively managed without these features.

Let’s start this analysis with a basic question. Is there any rational reason for VMware and Citrix to make peace with each other, and develop the desktop virtualization market in concert with one another instead of in competition with each other? In other words if Citrix were to add its value to the core pieces of VMware View, would this be a good thing or a bad thing?

Virtualization Management is Heating Up

Enterprises are urged to look at virtualization management as a separate purchasing decision from the decision to purchase and standardize upon a virtualization platform. Third party vendors are likely to be more in tune with the requirements of constituents other than virtualization administrators, and products from these third party vendors are more likely to provide robust support for multiple virtualization platforms.

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.
