CQRS - Event Sourcing ( 10/11 )

Hi Devs !!! we are in the road again :)

This time hosting an event about "CQRS / Event Sourcing" next Thursday 10th of Novembre at the Netcentric offices.

CQRS stands for Command Query Responsibility Segregation. The idea behind is to split the conceptual model into separate models for update and display, which it refers to as Command and Query respectively following the vocabulary of CommandQuerySeparation. The rationale is that for many problems, particularly in more complicated domains, having the same conceptual model for commands and queries leads to a more complex model that does neither well.

Adrian is a seasoned software developer having worked 16+ years in designing and implementing enterprise solutions in large scale projects.

His expertise includes strong hands-on technical skills with Enterprise Applications based on JEE technology, in Enterprise Integration area, database development, object oriented analysis/design, data modeling and client/server application development. In the last years he has been working on a service design platform where he applied CQRS architectural principles.

In this talk he will give us a deep dive into the CQRS / Event Sourcing architectural principles with an example implementation in Scala and Akka Persistence backed up by Cassandra for event journaling and Titan for snapshot persistence.

Building Reactive Applications with Akka - May 22th

Hola!

Ya tenemos aquí un nuevo evento, esta vez en colaboración con el grupo Scala Developers Barcelona. Conjuntamente tenemos el placer de presentar el evento "Building Reactive Applications with Akka" a cargo de Jonas Bonér, cofundador y CTO de Typesafe.

Las demandas y expectativas de las aplicaciones han cambiado drásticamente en los últimos años. Las aplicaciones actuales están desplegadas en una amplia gama de infraestructuras; desde dispositivos móviles hasta miles de nodos que se ejecutan en la nube, todo ello controlado por procesadores de múltiples núcleos. Los usuarios esperan que las aplicaciones reaccionen en milisegundos y que nunca fallen. Además, las aplicaciones modernas trabajan en entornos en que colaboran con una gran variedad de servicios de terceros.

En esta charla Jonas Boner presentará Akka detallando cómo puede ayudar a aportar en los cuatro principales características de las aplicaciones reactivas: Event - Driven, Scalability, Resilience y Responsive. Empezaremos con lo básico de Akka, continuando hacia algunos de sus módulos más avanzados como Akka Cluster y Akka Persistence, todos impulsados ​​a través de código con Scala y ejemplos prácticos.

El evento tendrá lugar el próximo 22 de Mayo a partir de las 18:15-18:30h, en la FIB (UPC Campus Nord, edificio B6, Barcelona). En esta ocasión y como se trata de un evento conjunto, os emplazamos a reservar tu plaza en Eventbrite.

No falteis, os esperamos!!
