Chapter 11. Business Aligning Case Studies

This chapter includes the following topics:

• Case Study 1: Profiling the Business Transaction

• Case Study 2: Defining SLAs

• Case Study 3: Optimizing the Business Transaction

• Case Study 4: Implementing QoS in a VoIP Environment

This chapter is composed of case studies that reinforce the material discussed so far in this book.

The first case study focuses more on the business side of the process and shows how to define and profile the business-critical application. It finishes up with a description of the characteristics learned and how they can be used in the ongoing process and future troubleshooting exercises.

The second case study shows how to take the information and relate it to produce a realistic service level agreement (SLA). It covers subjects such as metric definition, collection points, and thresholds to demonstrate good, poor, and bad performance.

The third case study addresses the optimization of a single transaction in a banking environment.

Finally, the fourth case study addresses the addition of quality of service (QoS) mechanisms to optimize the deliver of a voice-based application.
