Summary

A lightweight open framework for building fast and efficient cloud-native Java microservices:

• Open Liberty is fast to start up with low memory footprint and live reload for quick iteration.
• Simple to add and remove features from the latest versions of MicroProfile and Java EE.
• Zero migration lets you focus on what's important, not the APIs changing under you.
