Internet traffic spikes aren't what they used to be. It is now evident that even the smallest sites can suffer the attention of the global audience. This presentation dives into techniques to avoid collapse under dire circumstances. Looking at some real traffic spikes, we'll pinpoint what part of the architecture is crumbling under the load; then, walk though stop-gaps and complete solutions.

Communications and cooperation between development and operations isn't optional, it's mandatory. Flickr takes the idea of "release early, release often" to an extreme - on a normal day there are 10
full deployments of the site to our servers. This session discusses why this rate of change works so well, and the culture and technology needed to make it possible.

OpenDNS performs more than 8 billion DNS queries each day, generating mountains of data which we give back to our users. Processing and storing the interesting bits took a special map-reduce pipeline running on seven servers, backed by MySQL and memcached. I'll share all of the false starts and the techniques used to finally cope with more than half a gigabyte of log files per minute.

Disk I/O adds most to the latency of an application. For many MySQL based sites, performance problems become extremely painful when in addition to overnight growth, the data set fails to fit in the memory. Sharding strategies can be very difficult to implement overnight. Quick wins can be secured by optimizing data based on application access patterns & making working data sets fit in the memory.

At Facebook we serve billions of personalized pages every day, each of them computed from hundreds or thousands of separate pieces of data. This adds up to almost fifty million data requests per second against a dataset of over 50TB. Making every page fast in this environment is a serious challenge, and I'll be sharing some of the lessons we've learned trying to accomplish it.

Hypertable is an open source, high performance, distributed database modeled after Google's Bigtable. The design emphasis has been on scalability as opposed to support of ACID transactions and the relational model. This new class of database technology has proven to be well-suited for scalable Web 2.0 applications. Baidu, China's leading search engine, is now an official sponsor of Hypertable.
