Watch David Delabassée's JAX London session

JVMs in Containers, Towards a Perfect Symbiosis!

JAXenter Editorial Team

Container technologies such as Docker have rapidly become the de-facto way to deploy applications. In addition, emerging platforms, projects and tools (Knative, OpenFaaS, Fn Project, JIB, and more) either simplify or fully abstract building container images, which in turn makes leveraging containers with Java natural.

JVMs and containers are like fries and mayonnaise – better together!

During this technical session, we will discuss best practices of using the JVM with containers:

  • Techniques and tools to optimize containers size (e.g. jlink, Project Portola)
  • Approaches to improve applications startup time (e.g. CDS)
  • Benefits of using Graal SubstrateVM for AOT (Ahead-of-Time) compilation
  • The recent OpenJDK enhancements that improve the interactions between the JVM and Docker, etc.

Attend this session to understand how you can better leverage one of today’s most used programming platform, i.e. the JVM, with the most common tool to deploy code, i.e. containers.
