Quarkus makes it possible to write Java web applications ready to serve requests less than 20 milliseconds after start and occupying  less than 20 MB of memory. At the same time, its programming model feels much like the one of a traditional application server: There is persistence with JPA, JAX-RS for REST, CDI, transactions, most MicroProfile specifications and even a compatibility layer for some Spring APIs. Come and see how Quarkus makes all the above possible on top of GraalVM using a new technique called Compile Time Boot. Learn how exactly Quarkus eliminates runtime costs and how it circumvents the limitations of GraalVM. An 8 ms demo will be included.
