Managing Application
JOHN MICHELSEN

Gone are the days when you could test an interface to a single client/server app and know that you have performance covered. Today’s interconnected systems such as fully integrated packaged applications, ESB-based enterprise platforms, and SOA make ensuring high-performance from application components and solutions increasingly diffi cult. On top of that complexity, we are increasingly supporting technologies that are built and managed by distributed teams, both across organizational and geographic boundaries.

High-performance applications are critical to today’s business. Clearly operations teams must properly monitor production-ready systems to validate adherence to performance goals and Service Level Agreements (SLAs). But frankly, these operational monitors are often merely a postmortem of the work that takes place in development cycles. It is expensive or impossible to scale systems not built to high-performance standards from their outset in design and development.

The common practice of validating and tuning the performance of your applications in preproduction is when you have the worst ability to actually make any improvement in performance. This article describes the dynamic behind this maxim, and demonstrates how employing virtualization (with a virtual service environment) offers a solution to the load and performance testing team. ...

From Enterprise to Cloud, the Need for Virtualization Today Is Broad-Based
BY JEREMY GEELAN

Virtualization has become a critical part of the Enterprise IT strategy. Why has it become one of the most important change agents in our industry?

To answer this question I had the good fortune recently to be able to speak to a select group of top IT industry executives who joined me in the 4th Floor Reuters TV Studio overlooking Times Square in New York City for a special SYS-CON.

TV “Virtualization Power Panel.”
The executives – Red Hat CTO Brian Stevens; Citrix CTO Simon Crosby; Egenera CTO Pete Manca; Allen Stewart, Group Manager of Windows Virtualization at Microsoft; and Brian Duckering, Sr. Director of Products and Alliances at Symantec – were energized about virtualization for a variety of reasons, not least because it has already proven itself (the recent woes of VMware notwithstanding) to be a multi-billion dollar business.

Virtualization is currently changing quite dramatically and as Crosby said right at the beginning of the recording: “The good news is that there is enough there to keep us all employed as long as we want to keep working – in terms of changing IT and making it more efficient, more dynamic, and more streamlined.”

The change that Crosby was alluding to is not just the extension of virtualization beyond server consolidation to a more general role as a coupling mechanism between various levels of the IT stack, but also to the move by the industry beyond being a “one-company” technology, namely VMware. ...
