Python
Today, we are open sourcing the non-blocking web server and the tools that power FriendFeed under the name Tornado Web Server. We are really excited to open source this project as a part of Facebook's open source initiative, and we hope it will be useful to others building
Database
Database normalization is a technique for designing relational database schemas that ensures that the data is optimal for ad-hoc querying and that modifications such as deletion or insertion of data does not lead to data inconsistency. Database denormalization is the process of optimizing your database for reads by creating redundant
EC2
This tutorial will show you how to use Amazon EC2 and Cloudera's Distribution for Hadoop to run batch jobs for a data intensive web application. During the tutorial, we will perform the following data processing steps.... read more on Cloudera website

Many people in the Apache Hadoop community have asked Yahoo! to publish the version of Apache Hadoop they test and deploy across their large Hadoop clusters. As a service to the Hadoop community, Yahoo is releasing the Yahoo! Distribution of Hadoop -- a source code distribution that is based entirely
Hadoop
Facebook has the second largest installation of Hadoop (a software platform that lets one easily write and run applications that process vast amounts of data), Yahoo being the first. Learn how they do it and what are the challenges on DBMS2 blog, which is a blog for people who care
We are at the beginning of the multicore era. Computers will have increasingly many cores (processors), but there is still no good programming framework for these architectures, and thus no simple and unified way for machine learning to take advantage of the potential speed up. In this paper, we develop

Scale-up solutions in the form of large SMPs have represented the mainstream of commercial computing for the past several years. The major server vendors continue to provide increasingly larger and more powerful machines. More recently, scale-out solutions, in the form of clusters of smaller machines, have gained increased acceptance for

The Gear6 Web Cache hybrid DRAM-flash memory architecture allows for 5-10 times more memcache memory per unit of rack space than DRAM-only configurations, and cuts memory costs by 50%. Other software enhancements include a slab allocator that is more efficient than traditional memcache implementations due to its fine-grained bucket sizing.
Memcached
Memcached is generally treated as a black box. But what if you really need to know what's in there? Not for runtime purposes, but for optimization and capacity planning? Read more on Evan Weaver, a software developer working for Twitter (a contributor for Rails core and Mongrel).
Database
The most important aspect of a scalable web architecture is data partitioning. Most components in a modern data center are completely stateless, meaning they just do batches of work that is handed to them, but don't store any data long-term. This is true of most web application servers,
