What This Book Is Not

It's important to point out that this book isn't a WebSphere administration manual. Although this book can definitely complement a WebSphere administration guide, its purpose is to provide you with a strategy and methodology for planning your WebSphere platform's optimization and performance. So often, performance and scalability, as I'll discuss in Chapter 1, is considered achievable by simply purchasing lots of capacity and hardware. This is fundamentally wrong. What this book therefore explores is why you should set certain parameters for your platform's needs.
