46. @holly_cummins #RedHat java has shifted to the cloud
47. @holly_cummins #RedHat 13 MB footprint 0.014 s startup time modern Java REST app https://blog.openj9.org/2020/01/16/quarkus-and-eclipse-openj9-exceptional-performance-across-platforms/ https://www.redhat.com/en/resources/quarkus-infographic-supersonic-subatomic-java
