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

Rethinking REST in a Microservices World

April 19, 2016

Many of us are doing microservices wrong. We’re splitting our systems up into smaller and smaller services, paying all the costs that that entails, but only getting a taste of the benefits, and the problem is REST. Microservices are supposed to promise isolation, isolation from faults, isolation from load failures, but synchronous communication means failure and unresponsiveness bubbles back up through our services along our communication pathways, undermining the promises that microservices offer. To realise the full potential of microservices, we need to stop using REST as our go to, and start rethinking our architectures to use asynchronous communication. This presentation looks at how this can be achieved in a practical manner.
