This session will show how the combination of IBM WebSphere Application Server Liberty profile, IBM's application server for the cloud, and Netflix Open Source Software (OSS), can be used to build applications with high availability, auto-recovery, and continuous delivery at web scale. You will get an overview of the Netflix OSS projects and see how Liberty's extensibility makes it easy to integrate these projects with your application. We will share with you open source that IBM has made available to allow you to leverage the power of these projects within the Liberty programming model. Come see the benefits of a microservices architecture leveraging a combination of Netflix OSS and the WebSphere Liberty profile.
