OSGi

December 16, 2008 – OSGi

Description

OSGi is a Java-based component architecture that has gained a lot of traction recently. It is simple, provides dynamic updates of components and supports working with different versions of the same JAR or component. OSGi is used to build complex applications like Eclipse, application servers (GlassFish, IBM Websphere, OpenEJB, Oracle/BEA Weblogic, Jonas, JBoss), application frameworks (Spring, Guice), and more. We will discuss the following topics:

• The basic OSGi architecture (bundles, manifests and services)
• OSGi Implementations (Equinox, Felix, Knopflerfish)
• Concrete Uses of OSGi (Eclipse, …)
• Developing OSGi Bundles (Eclipse PDE, Maven, PAX-tools, …)
• OSGi Examples

Developing scalable, concurrent + fault-tolerant applications with Akka Actors

Tuesday, November 18, 2014

This presentation will cover the use of Akka Actors as a method of developing highly-scalable systems in a highly fault-tolerant manner. It will begin with a look at the Akka Actors and their asynchronous, message-passing, share-nothing nature. Next, we will look at some of the flexible options available to developers using Akka, such as using the Akka Event-Bus for inter-Actor communication, Persistent Channel Communication, PArent-Child relationships, and EventSourcing with Akka. Lastly, a full-featured example will illustrate how we can leverage the previous concepts to develop a CQRS-with-EventSourcing high-volume enterprise-class application with minimal effort. Although Akka is built on Scala, the examples presented here will be in Java (this is AJUG, right?)
