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.

Many people know how to use memcached, the popular caching system powering much of web1+. Most folks, though, don't know how not to use it, and how improper usage can cause data problems, poor site/application performance, and an incredibly grumpy DBA. Learn what memcached is good for, and what it's not good for from those that have learned the wrong way.

At OSCON 2008, Tim O'Reilly raised in his keynote a new challenge we face: Software as a Service. This panel discusses the work spawned by autonomo.us to inspire the Open Source and Software Freedom Movement to address the challenge. The talk will discuss the AGPL, a license designed to address these concerns, and the federated service model that must exist to succeed in addressing this problem.

Abstraction is a powerful servant, but a dangerous master. We code, design, think, debug ... on a tower of abstractions. Spolsky's Law tells us that "All abstractions leak". This talk explores why they leak, why that's often a problem, what to do about it; I also cover why sometimes abstractions SHOULD "leak", and how best to produce and consume abstraction layers.

We will present Eucalyptus -- Elastic Utility Computing Architecture for
Linking Your Programs to Useful Systems -- an open source software
infrastructure that implements IaaS-style cloud computing.
The goal of Eucalyptus is to allow sites with existing clusters and server
infrastructure to host an elastic computing service that
is interface-compatible with Amazon's AWS.

Nowadays, data is everywhere: databases, spreadsheets, the web...if only we could access it at on time, at the right place, in the right form...
Turning data into information is a struggle. Like diamonds are mined and cut to create jewels, so must data be extracted and transformed to create information.
Learn how the open source data integration tool Kettle helps to fight your data dragons.

This talk will discuss the on going effort to standardize the interfaces into the cloud. Currently every cloud provider has a unique, proprietary, API for consuming the services they offer. The Cloud Computing Interoperability movement aims to provide standards that will overcome vendor lock-in, benefit the consumers, and allow the cloud ecosystem to grow transparently.

The end of "scale-up" computing is near. The coming wave of web-scale
data is too big to justify exponentially increasing hardware costs for
decreasing returns. Apache's "Cloud Stack" (Hadoop, Lucene, HBase,
etc) is enabling Visible Technologies to move from a non-scalable
MS-exclusive platform to a large cluster processing millions of pieces
of content a day.Here's what we learned.
