Change is in the air. We got in touch with JAX London speakers to get a vision of what the future looks like for Java. Alex Soto shows off what Quarkus can do to make Java programs lighter and fast, Michael Inden takes a deep dive into Java 12’s new switch expressions, and Nir Koren gives tips for utilizing CI/CD for microservices. There’s plenty more, too: Thomas Buss takes a look at cloud-native Java with Micronaut, Markus Thömmes introduces us to Knative and shows us how powerful the combination of serverless and Kubernetes can be, and Dr. Carola Lilienthal writes about how to keep software architecture sustainable by managing technical debt. And that’s really only a sample of the feast on offer at JAX London.
