Invoking Oracle Functions from OIC by Niall Commiskey

Blog: PaaS Community

Introduction From the Oracle website –

Oracle Cloud Functions is a serverless platform that lets developers create, run, and scale applications without managing any infrastructure. Functions integrate with Oracle Cloud Infrastructure, platform services and SaaS applications. Because Functions is based on the open source Fn Project, developers can create applications that can be easily ported to other cloud and on-premises environments. Code based on Functions typically runs for short durations, and customers pay only for the resources they use.

These Functions can be written in a variety of languages – Java, Python, Node etc. You write and deploy the code, Oracle takes care of provisioning, scaling etc.

Think of blocks of code that generally do one thing, e.g. applying a discount to an order. These are stored as Docker images in a docker registry. They can be executed via CLI or HTTP request. We will be using the latter in our example. So how do Functions enhance the OIC experience? Here’s one use case – Say you are porting SOA Composites to OIC and you make use of Java Embedding in your BPEL process. Where shall I put that code in OIC? Read the complete article here.
