Fast and Distroless Java in Containers: the Recipe!

A containerized application that consumes less CPU, less memory and less bandwidth (by diminushing the container image size) will generates immediate savings on cloud workloads. Sadly, containerizing Java applications and optimizing them for running inside containers has been quite challenging until recently. Come and see how to improve the situation with distroless container imagesEclipse OpenJ9 (an open source Java virtual machine) and custom Java runtime images.
