serverless

Jakarta EE provides a comprehensive set of vendor neutral, open specifications that can be used for developing modern, cloud native Java applications from the ground up. However there are also a lot of existing applications build on top of it’s predecessors J2EE and Java EE before the specifications moved to the Eclipse Foundation.

In this session we discuss modernization pathways that make traditional Java enterprise applications more Cloud Native while preserving the existing investments. As a concrete example we’ll take a backend application running on a classic application server that provides RESTful services using Eclipse Jersey. We’ll be replatforming it to run as a serverless function on AWS Lambda with minimal code changes.

EclipseStore Coding - Build Ultra-Fast Java Persistence for Microservices and Serverless

Markus Kett (Micro Stream Software GmbH)

IoT, virtual reality, blockchain, AI and machine learning are the software solutions of the future. All of these apps produce and consume tons of data. The amount of data is now exploading lika a data big bang. Two factors are most critical for all of these apps: best possible performance, and lowest data storage costs. Today's database systems struggle to keep pace, are very expensive in the cloud and challenging with cloud-native microservices and serverless architectures.

Afraid of Java cold starts in Serverless? Fear not, Java is super fast!

Ondro Mihalyi (Omnifish OU)

For years, we’ve been told that Java suffers from cold starts in AWS Lambda and Serverless in general. Believe it not. Java is extremely fast to start, the simplest Java program starts in milliseconds. It’s the Java frameworks and libraries that slow things down in general. But not all of them…

Event Driven IoT - Serverless Functions for OSGi

Tim Ward (Kentyou)

In an ever increasing race to increase scalability, reduce configuration and decrease hosting costs “Serverless” computing promises to run your business logic “on demand” without the need for fixed infrastructure. As a dynamic, modular platform OSGi makes an ideal platform upon which to deploy your serverless functions. Furthermore, OSGi’s Requirements and Capabilities model allows for more complex serverless functions to be dynamically assembled and deployed in response to incoming events.
