Featured Talk / Main Session

Hadoop: Divide and Conquer Gigantic Datasets


Moore’s law has finally hit the wall and CPU speeds have actually decreased in the last few years. The industry is reacting with hardware with an ever-growing number of cores and software that can leverage “grids” of distributed, often commodity, computing resources. But how is a traditional Java developer supposed to easily take advantage of this revolution? The answer is the Apache Hadoop family of projects. Hadoop is a suite of Open Source APIs at the forefront of this grid computing revolution and is considered the absolute gold standard for the divide-and-conquer model of distributed problem crunching. The well-travelled Apache Hadoop framework is curently being leveraged in production by prominent names such as Yahoo, IBM, Amazon, Adobe, AOL, Facebook and Hulu just to name a few.


In this session, you’ll start by learning the vocabulary unique to the distributed computing space. Next, we’ll discover how to shape a problem and processing to fit the Hadoop MapReduce framework. We’ll then examine the incredible auto-replicating, redundant and self-healing HDFS filesystem. Finally, we’ll fire up several Hadoop nodes and watch our calculation process get devoured live by our Hadoop grid. At this talk’s conclusion, you’ll feel equipped to take on any massive data set and processing your employer can throw at you with absolute ease.

Basic Concepts / First Session

Encryption Boot Camp on the JVM

Does your application transmit customer information?  Are there fields of sensitive customer data stored in your DB?  Can your application be used on insecure networks?  If so, you need a working knowledge of encryption and how to leverage Open Source APIs and libraries to make securing your data as easy as possible.  Encryption is quickly becoming a developer’s new frontier of responsibility in many data-centric applications.

In today’s data-sensitive and news-sensationalizing world, don’t become the next headline by an inadvertent release of private customer or company data.  Secure your persisted, transmitted and in-memory data and learn the terminology you’ll need to navigate the ecosystem of symmetric and public/private key encryption.
