Learn the tricks of the trade so you can build and architect applications that scale quickly--without all the high-priced headaches and service-level agreements associated with enterprise app servers and proprietary programming and database products. Culled from the experience of the Flickr.com lead developer, Building Scalable Web Sites offers techniques for creating fast sites that your visitors will find a pleasure to use. Creating popular sites requires much more than fast hardware with lots of memory and hard drive space. It requires thinking about how to grow over time, how to make the same resources accessible to audiences with different expectations, and how to have a team of developers work on a site without creating new problems for visitors and for each other. Presenting information to visitors from all over the world Integrating email with your web applications Planning hardware purchases and hosting options to have as much as you need without breaking your wallet Partitioning and distributing databases to support large datasets and simultaneous transactions Monitoring your applications to find and clear bottlenecks * Providing services APIs and using services from other providers to increase your site's reach and capabilities Whether you're starting a small web site with hopes of growing big or you already have a large system that needs maintenance, you'll find Building Scalable Web Sites to be a library of ideas for making things work.

Pressestimmen
"Cal Henderson, der Autor von Building Scalable Web Sites, ist im Hauptberuf bei Yahoo! angestellt und dort Engineering Manager für flickr. Und diese Praxisnähe zieht sich durch das ganze Buch. Ob er die Architektur einer Web-Applikation durchgeht, die er mit einer geschichteten Süßspeise vergleicht, ob er die Hardware-Plattformen behandelt oder ein Plädoyer für eine vernünftige Entwicklungsumgebung hält: Überall merkt man, daß der Autor weiß, wovon er redet. [...] Es [das Buch] ist ein Muß für jeden, der eine einigermaßen frequentierte Site betreibt und hat die Chance, in die Liste meiner meist zerfledderten O'Reilly-Bücher aufzusteigen." - schockwellenreiter.de, August 2006
Synopsis
Slow websites infuriate users. Lots of people can visit your web site or use your web application - but you have to be prepared for those visitors, or they won't come back. Your sites need to be built to withstand the problems success creates. "Building Scalable Web Sites" looks at a variety of techniques for creating sites which can keep users cheerful even when there are thousands or millions of them. Flickr.com developer, Cal Henderson, explains how to build sites so that large numbers of visitors can enjoy them. Henderson examines techniques that go beyond sheer speed, exploring how to coordinate developers, support international users, and integrate with other services from email to SOAP to RSS to the APIs exposed by many Ajax-based web applications. This book uncovers the secrets that you need to know for back-end scaling, architecture and failover so your websites can handle countless requests. You'll learn how to take the "poor man's web technologies" - Linux, Apache, MySQL and PHP or other scripting languages - and scale them to compete with established "store bought" enterprise web technologies.Toward the end of the book, you'll discover techniques for keeping web applications running with event monitoring and long-term statistical tracking for capacity planning. If you're about to build your first dynamic website, then "Building Scalable Web Sites" isn't for you. But if you're an advanced developer who's ready to realize the cost and performance benefits of a comprehensive approach to scalable applications, then let your fingers do the walking through this convenient guide.

Eines der besten Bücher, die ich seit langem zum Thema Skalierbarkeit und Web-Sites gelesen habe. Das Buch erklärt eigentlich alles, was man zum Thema "Wie baue ich einen webbasierten Service im Internet auf" wissen muß. Die Beispiele beziehen sich auf PHP und MySQL, sind aber auch übertragbar - auch Ruby on Rails-Programmierer werden von dem Buch etwas haben.
Das Buch vermittelt keine kompletten Neuheiten, aber ich hatte beim Lesen viele interessante Aha-Effekte.
Wer sich nur eine Website für fünf Besucher bauen will, für den ist das Buch uninteressant - aber sobald es in höhere Lastbereiche und damit andere Anforderungen und Skaliarbarkeit geht, da gibt das Buch viele Antworten.
Der Autor ist übrigens Entwickler bei Flickr und bringt viele interessante Praxisbeispiele.

Scalability -- A Hot Topic
13. Juni 2006
Von Brett Merkey
- Veröffentlicht auf Amazon.com
Format:Taschenbuch
When I first starting working on Web application development teams, I was a bit overwhelmed by the number of skills and range of knowledge needed to drive the project through establishing the technical foundations; design, development and testing iterations; to final staged release. Lots of things got discussed in team meetings that I had barely a clue about. Not only do I wish I had this book *then,* I wish all members of my teams could have it *now.*
Cal Henderson has a wide background in the area and is lead developer for Flickr, the photo sharing site that has gained deserved popularity and is often mentioned as the quintessential Web 2.0 application.
The author does an excellent job of spreading out before you the whole process at a high enough level so the book can be valuable for managers, designers, and all sorts of people involved in putting out the final product.
His focus is on program design and design implementation issues, not programming as such. Code is not neglected. Many points regarding design implementation are made with code examples and solutions.
I find this book so personally valuable in grounding me in a complex process, I give it the highest Amazon rating even though I found aspects of the book's organization to be completely incomprehensible. This is a book about scalable Web sites and applications but the author does not define scalability nor does he deal with the broad Web issues (like the scaling myth) until 60% into the book! Chapter 9, titled "Scaling Web Applications" should have been much closer to the beginning since it was a high-level view with no code, as the other chapters. I was also befuddled with placing the chapter on internationalization, localization, and Unicode so early in the book -- even before the chapter on data integrity and security. There is nothing like a mind-numbing Unicode glyphs and grapheme discussion to kill the pacing of a book! Skip the chapter entirely or read it last.
Organization anomalies aside, the author has a good writing style and he does not view humor as a blunt instrument. His four page analogy between layered architecture and an English trifle was worth the space he took. That's high praise from a guy who does a job that Henderson likens to whipped cream.

I wish all software developers would read this

Unfortunately, I'm finding that there are still some in the software industry--from "two guys in a garage" to the largest corporation--don't know, follow, or believe software best practices. Suddenly when something goes wrong (e.g. the wrong version of a file was deployed, changes can't be rolled back, the application won't scale), everyone scrambles in an effort to figure out what happened. Oftentimes, if simple software practices were followed, many of these issues would never surface.
This book does a tremendous job identifying many of these best practices, identifies how to easily implement them--in almost any situation, and discusses application scaling techniques. As the book mentions, scalability is made up of three characteristics:
* The application can accommodate an increase in users
* The application can accommodate an increase in data
* The application is maintainable
Like any good book on application scalability, this one begins discussing the tiered architecture that is common in so many modern applications, and is a fundamental step in creating any truly scalable application. This follows into a discussion on source control--another fundamental part of keeping the application maintainable.
The author briefly discusses security issues by touching on cross-site scripting (XSS), SQL injection, and the like. The discussion is well written and thorough for the amount of time spent on the topic.
Finally, the author discusses many of the issues related to deployment of web applications, including system monitoring and alerting. There is also an excellent section on load balancing, techniques to keep databases scalable, and caching. Finally, the author ties the final section together by showing how to take data from a live production environment and use that information to continually improve the application.
This is an excellent read--a must if you are in the business of creating web applications. Whether your applications expect loads of 10 users or a million users, the techniques discussed in this book will make your application perform better and be easier to maintain.

Starts out off-topic, and then WHAM...
14. Juni 2006
Von I. Code Freeley
- Veröffentlicht auf Amazon.com
Format:Taschenbuch
...it's all there.
Maybe it's my background, but I found the first seven chapters to be....dull, and not directly about scalability. To be honest, I almost set the book aside and considered it money NOT well-spent. Then things started to heat up in Chapter 8, and in Chapter 9 it all comes together. That one chapter (9) is the highest density of useful information about website scaling that I've ever seen. There are literally gems on every page.
Make no mistake. This book is more of an overview of the landscape, with brief asides that are clearly brain-dumps from his Flickr experience. The author manages to touch on every topic area that matters, and provide simple overviews of the options available and when they should be applied. In that sense it's more like an informal design patterns book (lots of "yeah, I knew that" and "Ah! I had a feeling there was a pattern there" moments), with just enough detail to let me do intelligent googling for deeper insights on analysis, design, and construction of scalable systems.
Chapters 8, 9, and 10 make the book worth every penny.
