Red Hat Openshift Application Runtimes Components
Thorntail (formerly WildFly Swarm) offers an innovative approach to develop and run Java EE applications by packaging them with just enough of the server runtime to "java -jar" your application. It is MicroProfile compatible, so it accelerates the transition from monoliths to microservices while taking advantage of existing Java EE experience. Using Thorntail with OpenShift Application Runtimes allows you to modernize your applications by adding microservices capabilities that are optimized for deployment on OpenShift.
Eclipse Vert.x is a toolkit to build distributed and reactive applications on top of a Java Virtual Machine (JVM) using an asynchronous, non-blocking development model. Using Eclipse Vert.x with OpenShift Application Runtimes allows you to quickly develop high-concurrency, low-latency Java applications that are optimized for deployment on OpenShift.
Spring Boot is a Java application runtime for the development of cloud native applications. Red Hat tests, verifies, and optimizes Spring Boot for deployment to OpenShift. Red Hat supports the JWS Embedded Tomcat container for use with Spring Boot applications.
