The Virtualization Practice

Both Infrastructure Performance Management and Applications Performance Management vendors who are targeting the virtualization and cloud markets have realized that new and unique data is needed in order to performance manage these new environments and the applications that run on them. This is dramatic departure from the old physical world where most vendors simply relied upon the data that were provided via standard OS API’s to infer systems and applications performance.

GestaltIT Tech Field Day: Virtualization Line Up

I participated in GestaltIT’s TechFieldDay which is a sort of inverse conference, where the bloggers and independent analysts go to the vendors and then discuss the information they have received. We visited the following virtualization vendors:

* vKernel where we were introduced to their Predictive Capacity Planning tools
* EMC where we discussed integration of storage into the virtualization management tools as well as other hypervisor integrations
* Cisco where CVN and CVE were discussed in detail.

Depth vs. Breadth in Virtualization Performance Management

Enterprises who are going to support business critical and performance critical applications on a virtual infrastructure should at the minimum address two needs. The first is to get a true and complete picture of Infrastructure Performance based upon Infrastructure Response Time. The second is to put in place the tools required to monitor these applications in production.

GestaltIT Tech Field Day: Storage Line Up

I participated in GestaltIT’s TechFieldDay which is a sort of inverse conference, where the bloggers and independent analysts go to the vendors and then discuss the information they have received. We visited the following storage vendors:

* Data Robotics where we were introduced to the new Drobo FS
* EMC where we discussed stretched storage and other interesting futures
* HP where we were introduced to the IBRIX products

One thing I have learned in the time I have spent working in IT is that no software product, out of the box, will do everything that you want it to do. This especially goes for VMware’s vCenter Server. This is a great product but yet still has its shortcoming. vCenter will perform a lot of the tasks that we need to do and has the ability to report on a information we need to know about in our virtual environments but unfortunately not everything we need to know about can be easily found in bulk about multiple servers.

Since coming out with VMware vSphere and Virtual Infrastructure Security: Securing the Virtual Environment, I have continued to consider aspects of Digital Forensics and how current methodologies would be impacted by the cloud. My use case for this is 40,000 VMs with 512 Servers and roughly 1000 tenants. What I would consider a medium size fully functioning cloud built upon virtualization technology where the environment is agile. The cloud would furthermore contain roughly 64TBs of disk across multiple storage technologies and 48TBs of memory. Now if you do not think this exists today, you were not at VMworld 2009, where such a monster was the datacenter for the entire show and existed just as you came down the escalators to the keynote session.

Infrastructure Performance Management Heats Up

Infrastructure Performance Management is the single most important performance and capacity management issue that owners of a virtual environment need to address. The reason for this is that since the low hanging fruit has been virtualized, what is left is business critical and performance critical applications in the hands of applications owners and their business constituents. In order to convince these groups that the virtual infrastructure is performing acceptably in support of these important applications Operations groups in charge of virtual environments need to move beyond trying to infer infrastructure performance from resource utilization patterns.

Citrix have invested an unspecified amount of money in Kaviza whose grid architecture eliminates the expensive infrastructure that VDI solutions. With Kaviza’s solution all the functionality needed to provision and manage virtual desktops is consolidated into a single virtual appliance that scales on commodity servers. Will this announcement herald a major take-up of VDI? Indeed, can you really offer a turnkey solution to support your desktop centralisation strategy?
