Graal Development Kit for Micronaut
Build portable cloud native Java microservices that start instantly and use fewer resources to reduce compute costs.
The Graal Development Kit for Micronaut (GDK) is a curated set of open source Micronaut® framework modules designed from the ground up for ahead-of-time compilation with GraalVM Native Image, resulting in native executables ideal for microservices.
Benefits of the Graal Development Kit for Micronaut
Write applications once and run them on any public cloud. Develop applications without worrying about cloud-proprietary APIs and libraries, and thus prevent cloud lock-in.
Graal Development Kit for Micronaut applications compiled by GraalVM Native Image start instantly, provide peak performance with no warm-up, and have a small memory footprint.
Reduce development time with out-of-the-box cloud service integrations and compile-time validation that detects errors at build time, not runtime.
Run Graal Development Kit for Micronaut applications in production on Oracle Cloud with full commercial support at no additional charge.

MuShop: A large cloud native reference application
MuShop for Micronaut is a showcase using several Oracle Cloud Infrastructure services in a unified application. MuShop was originally written to demonstrate a variety of cloud services using multiple programming languages and frameworks. Oracle has ported MuShop to use Java, the Micronaut framework, and GraalVM Native Image to demonstrate that GDK improves developer productivity, efficiency, and cloud portability.
MuShop implements microservices compiled by GraalVM Native Image into native executables deployed to Kubernetes. MuShop, a reference to ecommerce, is composed of nine microservices. You can run MuShop locally using Oracle Database in a container by using docker-compose. The preferred option is to deploy it to Oracle Cloud and then leverage services such as Oracle Container Engine for Kubernetes, Oracle Autonomous Transaction Processing, Oracle Functions, and a complete networking stack.

Micronaut
The Micronaut framework provides Java developers with a huge productivity boost. By avoiding runtime reflection in favor of annotation processing, Micronaut improves the Java-based development experience by detecting errors at compile time instead of runtime, and improves Java-based application start time and memory footprint.

GraalVM
GraalVM’s advanced optimizing compiler technology can accelerate any Java workload running on the HotSpot JVM, but GraalVM Native Image’s ahead-of-time compilation provides a whole new way to deploy Java applications ideal for containerization. At build time, GraalVM Native Image analyzes a Java application and its dependencies to identify just what classes, methods, and fields are absolutely necessary and generates optimized machine code for just those elements.
