Replication Under Scalable Hashing: A Family of Algorithms for Scalable Decentralized Data Distribution Typical algorithms for decentralized data distribution work best in a system that is fully built before it first used; adding or removing components results in either extensive reorganization of data or load imbalance in the system. We have developed a family of decentralized algorithms, RUSH (Replication Under Scalable Hashing), that maps replicated objects to a scalable collection of storage servers or disks. RUSH algorithms distribute objects to servers according to user-specified server weighting. While all RUSH variants support addition of servers to the system, different variants have different characteristics with respect to lookup time in petabyte-scale systems, performance with mirroring (as opposed to redundancy codes), and storage server removal. All RUSH variants redistribute as few objects as possible when new servers are added or existing servers are removed, and all variants guarantee that no two replicas of a particular object are ever placed on the same server. Because there is no central directory, clients can compute data locations in parallel, allowing thousands of clients to access objects on thousands of servers simultaneously.
Web Analytics: An Hour A Day is the first book by an in-the-trenches practitioner of web analytics. It provides a unique insider’s perspective of the challenges and opportunities that web analytics presents to each person who touches the Web in your organization. Rather than spamming you with metrics and definitions, Web Analytics: An Hour A Day will enhance your mindset and teach you how to fish for yourself. Avinash Kaushik is a expert in web analytics and author of the top-rated blog Occam’s Razor (http://www.kaushik.net/avinash). In this book, he goes beyond web analytics concepts and definitions to provide a step-by-step guide to implementing a successful web analytics strategy. His revolutionary approach to web analytics challenges prevalent thinking about the field and guides readers to a solution that will provide truly informed and actionable insights.
Building, scaling, and optimizing the next generation of web applications. 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

Lustre® is a scalable, secure, robust, highly-available cluster file system. It is designed, developed and maintained by Cluster File Systems, Inc. The central goal is the development of a next-generation cluster file system which can serve clusters with 10,000's of nodes, provide petabytes of storage, and move 100's of GB/sec with state-of-the-art security and management infrastructure. Lustre runs on many of the largest Linux clusters in the world, and is included by CFS's partners as a core component of their cluster offering (examples include HP StorageWorks SFS, and the Cray XT3 and XD1 supercomputers). Today's users have also demonstrated that Lustre scales down as well as it scales up, and runs in production on clusters as small as 4 and as large as 25,000 nodes. The latest version of Lustre is always available from Cluster File Systems, Inc. Public Open Source releases of Lustre are available under the GNU General Public License. These releases are found here, and are used in production supercomputing environments worldwide.

Hi, I stumbled on your site and I am thinking about starting a website. I haven't received a good answer about what I should use to build it, so I thought I would give it a shot. I am a windows guy. I know .Net and ASP and how to build web sites using that stack. But I notice most sites use LAMP and that's what most people talk about using. What's wrong with using Windows? .Net Programmer
