For decades, Java has been able to invoke native programs on an operating system. JNI (Java Native Interface) and JNA (Java Native API) are commonly used to invoke native programs (Java Native Access). In recent years, Java has gained the ability to run JVM apps natively. In other words, the JVM apps are binary executables with no dependency on the Java runtime.
Now Java apps start up in milliseconds, instead of seconds. seconds. This is a game-changer if you're scaling up to accommodate millions of requests, while saving money by adopting a serverless environment. For years, developers have chosen to use serverless environments with Node.js, Python, and Go. The ability to go serverless with Java (or Kotlin) brings the opportunity to an important developer community.
