If I learned one thing from the time I spent at last week’s Gartner Data Center conference, it’s that the greater IT community still isn’t entirely on board with the family of technologies this publication holds near and dear, but it will jump on soon enough — and virtualization will spur it along.
Kicking off the event with a keynote titled “The Future of Infrastructure and Operations,” analyst Thomas Bittman predicted that virtualization will be the most “impactful” infrastructure and operations technology through 2012, and that it will help to transition IT into what Gartner is calling the real-time infrastructure (RTI) era. Virtualization will play this facilitator role, he said, because aside from simply being used to consolidate servers, virtualization technology enables the layers of abstraction necessary for alternative delivery models like grid computing, SaaS and cloud computing, all of which will touch different parts of the RTI elephant.
Until we achieve the nirvana that is RTI, however, we should prepare to see virtualization impact everything, said Bittman in a later session, from costs to rollout time to shared services. For example, while Gartner research finds that only 6 percent of virtualization-friendly workloads are actually running in virtualized environments, this number will increase sharply as we approach Gartner’s prediction of 4 million x86-based virtual machines by 2009. We also should expect to see, among other virtualization-based innovations, an increase in software appliances (essentially, pre-packaged applications complete with their own virtual operating systems) and employee-owned PCs that contain locked-down, virtual environments for job-related applications and tasks.
Bittman also predicts virtualization will continue to have a disruptive effect on software licensing as workloads begin to move dynamically across both physical and virtual machines. Illustrating the current state of licensing as it relates to virtualization, an impromptu survey of attendees in the packed MGM Grand meeting room showed 28 percent partaking in custom negotiations for licensing their virtualized environments, 24 percent saying licensing issues have limited their virtualization efforts, and 21 percent claiming virtual licensing concerns are affecting software choices.
Gartner analyst Carl Claunch also sang the praises of virtualization in his keynote highlighting the “Top Ten Disruptive Technologies Affecting the Data Center.” Calling virtualization a “Swiss Army knife tool” for IT, Claunch said it is a “real disservice” to consider virtualization as a technology only to be used for consolidation or slicing up servers. The layers of abstraction that virtualization enables, he commented, are great for eliminating the “dense spiderwebs” of interdependencies in the datacenter, and the ability of virtualization to make hardware generic leads to on-the-fly movement of work. In addition, virtualization can accomplish the opposite of slicing up servers, instead allowing users to aggregate resources to resemble one big SMP machine.
This latter use of virtualization is not unlike the concept of server fabrics, which Claunch also cited as a disruptive technology. A step beyond blades, server fabrics are most realistic as entirely virtualized blade racks that users can partition to create whatever size or type of systems they need in terms of memory, CPUs, I/O, etc. Not surprisingly, I/O virtualization plays a big role in making server fabrics realize their full potential.
Speaking of the aforementioned cloud computing (because how could a week go by without doing so), Bittman also shared his thoughts on the technology, its current state and how it fits into the RTI concept. RTI, he explained, is all about creating a service-oriented infrastructure where IT is shared across users, divisions, applications and beyond. The ultimate realization of a cloud of computing resources where service requirements go in and services come out — all transparently — fits right into what RTI is looking to accomplish, but for now, believes Bittman, cloud computing is pretty much a way to achieve scale. There is a lot of smoke, he said, but little fire, as current (and recently announced) offerings simply lack the service level management and the policy enforcement capabilities needed for a mature, enterprise-ready solution. However, he said, cloud computing certainly is “pointing toward the future” and certainly is a strategy to be aware of in the years to come.
Personally, I’m inclined to agree with Bittman about the current state of cloud computing as it relates to doing it on a grand scale — a la Google — but I believe it will be a reality in the datacenter sooner than some might expect. IBM, for its part, understands that baby steps are necessary, and therefore is planning for its first Blue Cloud offering to be in the form of an IBM BladeCenter — far from a Web-scale collection of servers. What’s more, solutions like Appistry’s Enterprise Application Fabric (or GigaSpaces XAP or DataSynapse FabricServer, to name a few) already do a good job forming “clouds” and allowing for high availability, and they’re improving every day when it comes to policy-based automation and SLAs. Obviously, there is some work to be done along the lines of education and open standards before niche solutions like this become widespread, but I believe the foundation of cloud computing already has been laid.
For those of you interested in scale, I would suggest reading our interview with ScaleOut Software founder and CEO William Bain. Distributed caching solutions are gaining in popularity, but not everybody is aware of all the players in the space; most of us tend to focus on the more well-known vendors like GigaSpaces and Tangosol (now part of Oracle) and GemStone. However, other companies are doing their own things to deliver massive scale and low latency, and Bain does a nice job of differentiating ScaleOut from the others.
I also should point to our special section, featuring two articles relating to the Open Grid Forum’s activities at last month’s SC07 conference. OGF is doing some great work toward achieving interoperability among both enterprise and production grids, and they showcased both initiatives in Reno. As I mentioned when the original announcements were made during the show, the grid market has come a long way by having major middleware and job-scheduling solutions being able to interoperate.
