1. Vert.x is an asynchronous, event-driven application platform similar in style to Node.js, except it runs on the JVM. It supports several JVM languages, including Javascript, and uses a multi-reactor event loop to handle a very high number of concurrent connections. Clustering is built-in and remarkably easy to use, and the Vert.x event bus makes passing messages between components or applications simple. With JSON as the native message format, and a SockJS client that speaks directly to the bus, pushing event-based messages to the browser has never been easier.

    In this talk I will introduce the Vert.x platform. I will discuss the pros and cons of Vert.x compared to other platforms like Node.js, and we'll look at some example code. I will finish up by writing a simple application that pushes JSON messages from a server cluster to the mobile browser in just a few lines of Javascript.

  2. This talk will address valuable lessons learned with the current versions of HBase. There are inherent architectural features that warrant for careful evaluation of the data schema and how to scale out a cluster. The audience will get a best practices summary of where there are limitations in the design of HBase and how to avoid those. In particular, we will discuss issues like proper memory tuning (for reads and writes), optimal flush file sizing, compaction tuning, and the number of write ahead logs required. Further, there is a discussion of the theoretical write performance, in comparison to those observed on real clusters. A collection of cheat sheets and example calculation for cluster sizing rounds out the talk towards the end.

  3. Is Amazon's new managed, lower cost, petabyte scale warehousing solution a game changer? We'll review the costs and discuss what does (or does not) make Amazon Redshift reliable, scalable and effective. We'll dive into the technical details behind the query and storage engines and we'll expose what works well and what does not. This talk should benefit both those that are and are not already part of the Amazon Web Services ecosystem.

Data IO showcases how to leverage today's applications and open-source frameworks to connect tens or hundreds or even millions of devices, things and people, and with any luck, make some sense of the data being captured. We'll show you not only how the pieces fit together, but also why these platforms are capable of doing what they do.
