Capacity planning is a well known discipline, particularly for sites that have a mainframe oriented background. The explosive growth of Internet sites and E-commerce has presented new challenges in managing performance and capacity. In many cases, time constraints and business demands can prevent normal capacity planning techniques from being applied. Classic datacenter capacity planning methods can be adjusted and successfully applied to this new Internet-centric computing environment. This BluePrint charts a course through the available techniques and tools, examines timescales and return on investment for different methodologies and provides a framework for decomposing big problems into solvable subproblems.
Book Description
Editorial Reviews
Amazon.com Review
The demands placed on a server farm by e-commerce and other Internet services differ from those imposed by longer-studied and better-understood processing tasks, largely because the potential demand for publicly accessible Internet services is practically infinite. Capacity Planning for Internet Services takes a careful look at traditional mainframe capacity planning techniques in light of the Internet's characteristics, evaluating their effectiveness in the new environment. The book offers new tools, formulas, and tables for use in estimating server requirements (they focus on the Sun Microsystems product line) for Internet work.
Ideal for system administrators, design engineers, database administrators, and anyone else involved in planning an upgrade path for an Internet-connected Sun environment, this book spends a lot of time documenting the factors that can create performance bottlenecks in Solaris servers and explaining how to measure peak loads. Hourly, monthly, seasonal, and special load increases are modeled mathematically, and the authors offer ideas for planning hardware capacity to match demand. They're explicit in their recommendations, calling for specific processor speeds, disk capacities, bandwidth provisions, and other specifications. Throughout, the emphasis is on keeping server capacity just slightly ahead of user requirements, so as to minimize expense. --David Wall
Topics covered: Models for predicting Internet users' demands upon Sun servers providing database lookups, transaction processing, and other services. Strategies for documenting user demand, tools for making observations, mathematical models for making predictions, and processes for planning capacity are all detailed.

Not a captivating read, but a good introduction,
By sporkdude "sporkdude" (San Jose, Ca United States) - See all my reviews
This review is from: Capacity Planning for Internet Services (Paperback)
Okay, this is not a book you'd take to the beach. If you think it is, you're just strange. Anyways, someone gave this book to me because he didn't need it anymore, and learned that I setting up a server for stress testing. Not being an expert in capacity planning, this provided a good introduction to what some of the expectations were to setting up a server environment.This book is not too readable; it lacks fluidity, and is sometimes repetitive. Of course, what would anyone expect from this type of book? One gripe I have with this book is that it's a little too skewed towards to overall management, as opposed to more technical aspects. For example, it concentrates on how to file a problem ticket more than monitoring network statistics. This book gives a good idea on how the process works to set up a plan and how to monitor parts of the system. It doesn't delve to deep into commands, specific examples, and goes in too deep for some parts (like disk capacity), but not too deep into other parts (like memory). It's worth reading, it's a good overview, and it's a template for the few who need to set-up the system. It won't help as technical reference, or help you once you're in front of the computer however.
