Effective Performance Engineering

Chapter 3. Proven Practices of Performance Engineering

To explore the proven practices of Performance Engineering, we will start with the requirements, architecture, and design; hit some of the highlights of implementation; and walk you through a real-life scenario. The objective of this chapter is to present a complete case study for each practice so you can begin to understand what it means for you, and to provide you with a story you can use and share with your team or organization.

Requirements, Architecture, and Design

Here is a list of proven practices for requirements, architecture, and design:

• Identify components

• Set performance budgets

• Establish acceptance criteria

• Plan for outliers

• Build in performance culture

• Prototype (and test)

Introduction

One of the questions many people ask themselves while adopting Effective Performance Engineering practices is, “How do I engineer configuration and applications before starting development?”

The building in Figure 3-1 represents the requirements of software and architecture architecture and design.

Today, teams architect and design within their own pillars, typically within a development or architecture team, and sometimes seen within a “Sprint 0” or other phase if the project or system is new.

The increasing complexity of composite applications, ...
