Develop microservices with Java technologies and support for other languages.
KumuluzEE is a lightweight framework for developing microservices using standard Java, JavaEE/JakartaEE technologies and migrating existing Java applications to microservices. KumuluzEE packages microservices as standalone JARs. KumuluzEE microservices are lightweight and optimized for size and start-up time. They fit perfectly with Docker containers.
KumuluzEE also provides extensions for developing common patterns in cloud native architectures, including configuration, logging, discovery, circuit-breakers, metrics, security, event streaming and more.
KumuluzEE supports Java, Node.js, Go and other programming languages. It also provides support for Blockchain, gRPC, GraphQL and many other advanced technologies.
Why should you choose KumuluzEE?
Smallest JAR
Fully cloud-native
Optimized for Docker and Kubernetes
KumuluzEE allows you to decompose Java applications into microservices and prepare them for cloud-native architecture. It allows you to create standalone lightweight Java and JavaEE/JakartaEE microservices that can be efficiently deployed, executed and scaled in the cloud on PaaS and Docker-like environments or as standalone applications. It also supports other languages, such as Node.js, Go, and more.
KumuluzEE microservices have a minimal footprint and require minimal or no configuration. KumuluzEE automates tasks related to the deployment and configuration of Java microservices, thus overcoming the major drawback of the microservice architecture and eliminating the need for an application server.

Reza Rahman,Senior Java Technologist, Author, Speaker
KumuluzEE truly brings microservice architecture to Java EE. Maven-ready, Fat JAR, modularized dependencies, Docker-ready, and pluggable web container makes it ready to be deployable in any cloud environment. If you are building apps using Java EE, start your microservice journey with KumuluzEE!
Arun Gupta,Vice President, Developer Relations at Couchbase
Although Java EE specifications and application servers have come down in size, it still wasn't a first technology choice for today's micro services developer when compared to say NodeJS or Spring Boot. That's now changed as KumuluzEE brings a light-weight, application server free way of creating micro services with the full power of Java, the JVM and JavaEE behind it! This innovative stack is truly a worthy Duke Awards winner in 2015.

Main benefits and features of KumuluzEE
Develop microservices with Java EE technologies
API gateway support and more
KumuluzEE provides full support for configuration, service discovery, health, logging, security, fault tolerance, circuit-breakers, event streaming, metrics, REST patterns and more. KumuluzEE microservices provide first-class support for API gateways
Pure Java EE based microservices
Develop pure Java EE based microservices using standard Java EE APIs and technologies and pack and execute them as stand-alone (Fat/Uber) JARs.
Leverage your existing knowledge to migrate applications
Leverage your existing Java EE knowledge and extend it to gradually migrate existing Java EE applications to microservices and cloud-native architecture with common cloud-native patterns.
Configurable Java EE environment
KumuluzEE is not a traditional Java EE app server, neither does it embed an app-server inside microservices. It provides configurable Java EE environment inside stand-alone JARs, which only require JRE (Java Runtime Environment) to execute.
Fastest start-up & small footprint
KumuluzEE generates pure, efficient Java microservices, which start considerably faster and have lower footprint than the majority of other Java microservice frameworks. Microservices are light-weight with small footprint, rapid start and container-ready.
Open source
KumuluzEE is fully open, standard-based and extensible.
Zero lock-in
KumuluzEE does not require any specific code. Everything is configured in pom.xml. You have the complete control over Java EE components you are using.
Integrated with Kumuluz family
KumuluzEE is fully integrated with KumuluzAPI, an innovative microservice API Management and other Kumuluz and KumuluzDigital products.
Compatible with Docker and Kubernetes
KumuluzEE microservices can be packed as Docker containers and provide full support for container environments. These microservices are fully compatible with Kubernetes.

Migration to microservices
Comparison with other solutions
When selecting a framework for Java microservices, you should consider the start-up time, size and memory footprint of a microservice.
The article Java EE microservices: why start-up time and size matter shows an interesting comparison of MicroProfile Java EE frameworks, including WebSphere Liberty, WildFly Swarm, Payara, TomEE and KumuluzEE.
KumuluzEE has achieved the fastest start-up time of 3 seconds and the smallest JAR size of 11 MB:
| Vendor | Microservice | JAR size (MB) | Start up Time (sec) |
|---|---|---|---|
| WebSphere Liberty | Session Voting | 35 | 8 |
| Payara | Session Schedule | 33 | 8 |
| KumuluzEE | Session Schedule | 11 | 3 |
