Scalability Rules is the easy-to-use scalability primer and reference for every architect, developer, web professional, and manager. Authors Martin L. Abbott and Michael T. Fisher have helped scale more than 200 hypergrowth Internet sites through their consulting practice. Now, drawing on their unsurpassed experience, they present 50 clear, proven scalability rules—and practical guidance for applying them.
Abbott and Fisher transform scalability from a “black art” to a set of realistic, technology-agnostic best practices for supporting hypergrowth in nearly any environment, including both frontend and backend systems.
For architects, they offer powerful new insights for creating and evaluating designs. For developers, they share specific techniques for handling everything from databases to state. For managers, they provide invaluable help in goal-setting, decision-making, and interacting with technical teams. Whatever your role, you’ll find practical risk/benefit guidance for setting priorities—and getting maximum “bang for the buck.”
• Simplifying architectures and avoiding “over-engineering”
• Scaling via cloning, replication, separating functionality, and splitting data sets
• Scaling out, not up
• Getting more out of databases without compromising scalability
• Avoiding unnecessary redirects and redundant double-checking
• Using caches and content delivery networks more aggressively, without introducing unacceptable complexity
• Designing for fault tolerance, graceful failure, and easy rollback
• Striving for statelessness when you can; efficiently handling state when you must
• Effectively utilizing asynchronous communication
• Learning quickly from mistakes, and much more
Martin L. Abbott, formerly COO of Quigo, spent nearly six years at eBay, most recently as SVP of Technology/CTO. He has held engineering, management, and executive positions at Gateway and Motorola. Michael T. Fisher, a veteran software and technology executive, spent two years as CTO of Quigo. Previously, as VP of Engineering & Architecture for PayPal, he led 200+ developers. Abbott and Fisher co-authored The Art of Scalability (Addison-Wesley).
In The Art of Scalability, Second Edition, leading scalability consultants Martin L. Abbott and Michael T. Fisher cover everything you need to know to smoothly scale products and services for any requirement. This extensively revised edition reflects new technologies, strategies, and lessons, as well as new case studies from the authors’ pioneering consulting practice, AKF Partners.
Writing for technical and nontechnical decision-makers, Abbott and Fisher cover everything that impacts scalability, including architecture, process, people, organization, and technology. Their insights and recommendations reflect more than thirty years of experience at companies ranging from eBay to Visa, and Salesforce.com to Apple.
You’ll find updated strategies for structuring organizations to maximize agility and scalability, as well as new insights into the cloud (IaaS/PaaS) transition, NoSQL, DevOps, business metrics, and more. Using this guide’s tools and advice, you can systematically clear away obstacles to scalability–and achieve unprecedented IT and business performance.
• Why scalability problems start with organizations and people, not technology, and what to do about it

If you're building pages for high traffic destinations and want to optimize the experience of users visiting your site, this book is indispensable.
"If everyone would implement just 20% of Steve's guidelines, the Web would be adramatically better place. Between this book and Steve's YSlow extension, there's reallyno excuse for having a sluggish web site anymore."

In this volume, four scholars at the Washington School Research Center (WSRC) at Seattle Pacific University present original research drawn from statistical studies of state educational data and from thousands of classroom observations carried out by The BERC Group. They assess the current state of math education and review its history and development. The authors also provide a dispassionate review of the extensive international, national, and state literature.
The in-depth observational research in Winning the Math Wars confirms that the real issue is neither the approach to teaching--traditional or reform--nor the type of curriculum. If America's goal of educational equity and excellence is to be achieved, then math teachers everywhere must be fully supported in developing the specific skills that are ideal for educating all students. The authors discussion focus on four principles for improving math teaching and learning: fidelity to reform efforts by all involved; an emphasis on instruction and instructional tools; the critical nature of mathematical knowledge; and the need for transformational change.
Winning the Math Wars is an important book for policy makers, school leaders, practitioners of mathematics education, parents, and anyone who wants to make sense of the "math wars."
