The Handbook of Application Delivery
A Network Professional's Guide to Ensuring Application Delivery by Dr. Jim Metzler, Industry Analyst with Ashton, Metzler & Associates
This 98-page, 2008 handbook presents the results of Dr. Jim Metzler's recent multi-client study on network performance management and application delivery. Along with a new framework for applications delivery, Metzler offers concrete ways that network professionals can move beyond the network plumbing and be part of the solution to application delivery challenges.

As recently as a few years ago, few IT organizations were concerned with application delivery. That has all changed. Application delivery is now a top of mind topic for virtually all IT organizations. As is described in this handbook, there are many factors that complicate the task of ensuring acceptable application performance. This includes the lack of visibility into application performance, the centralization of IT resources, the decentralization of employees and the complexity associated with the current generation of n-tier applications. Some of the IT organizations that were interviewed for this handbook want to believe that the challenges associated with application delivery are going away. They want to believe that application developers will soon start to write more efficient applications and that bandwidth costs will decrease to the point where they can afford to throw bandwidth at performance problems.
That follows in part because as explained in this handbook, the deployment of new application development paradigms1 such as SOA (Services Oriented Architecture), Rich Internet Architecture and Web 2.0 will dramatically increase the difficulty of ensuring acceptable application performance. It also follows because of the increasing management complexity associated with the burgeoning deployment of the virtualization of IT resources (i.e., desktops, servers, storage, applications), the growing impact of wireless communications, the need to provide increasing levels of security as well as emerging trends such as storage optimization.
Instead of reaching a point where the challenges associated with application delivery are going away, we are just ending the first phase of a fundamental transformation of the IT organization. At the beginning of this transformation, virtually all IT organizations were comprised of…(read more inside)
