We believe that one should never have to choose between productivity and scalability, which has been the case with traditional approaches to concurrency and distribution. The cause of that has been the wrong tools and the wrong layer of abstraction and Akka is here to change that. Akka is a unified runtime and programming model for scaling both UP (utilizing multi-core processors) and OUT (utilizing the grid/cloud). With Akka 2 this will be taken to a whole new level with its “Distributed by Design”. Akka 2 provides location transparency by abstracting away both these tangents of scalability by turning them into an operations and configuration task. This gives the Akka runtime freedom to do adaptive automatic load-balancing, cluster rebalancing, replication and partitioning. Akka is available at akka.io (under Apache 2 license).# vimeo.com/49485654 Uploaded 923 Plays 8 Likes 0 Comments
Doctor Who is the world’s longest running science-fiction TV series. Battling daleks, cybermen and sontarans, and always accompanied by his trusted human companions, the last Timelord has saved earth from destruction more times than you’ve failed the build.
Neo4j is the world’s leading open source graph database. Designed to interrogate densely connected data with lightning speed, it lets you traverse millions of nodes in a fraction of the time it takes to run a multi-join SQL query. When these two meet, the result is an entertaining introduction to the complex history of a complex hero, and a rapid survey of the elegant APIs of a delightfully simple graph database.
Armed only with a data store packed full of geeky Doctor Who facts, by the end of this session we’ll have you tracking down pieces of memorabilia from a show that, like the graph theory behind Neo4j, is older than Codd's relational model.# vimeo.com/49377272 Uploaded 873 Plays 12 Likes 0 Comments
Today, there are several trends that are forcing application architectures to evolve. Users expect a rich, interactive and dynamic user experience on a wide variety of clients including mobile devices. Applications must be highly scalable, highly available and run on cloud environments. Organizations often want to frequently roll out updates, even multiple times a day. Consequently, it’s no longer adequate to develop simple, monolithic web applications that serve up HTML to desktop browsers.
In this talk we describe the limitations of a monolithic architecture. You will learn how to use the scale cube to decompose your application into a set of narrowly focused, independently deployable back-end services and an HTML 5 client. We will also discuss the role of technologies such as NodeJS and AMQP brokers. You will learn how a modern PaaS such as Cloud Foundry simplifies the development and deployment of this style of application.
