With its open source Fn project, Oracle is looking to make a splash in serverless computing.
Fn is a container native serverless platform that can be run on-premises or in the cloud. It requires the use of Docker containers. Fn developers will be able to write functions in Java initially, with Go, Ruby, Python, PHP, and Node.js support planned for later. Applications can be built and run without users having to provision, scale, or manage servers, by using the cloud.
Fn, as its name implies, relies heavily on functions, which are small blocks of code that generally do one simple thing. In a function, developers focus just on just the task they want the function to perform.
