Compute Services

Announcing IBM Bluemix OpenWhisk Beta

Share this post:

We’re pleased to officially announce that the IBM Bluemix OpenWhisk compute service is an open Beta offering. The experimental offering period period began in February, 2016 and the Beta period began in September.

OpenWhisk is an open source, serverless programming platform for developers to create “actions“- small pieces of code in their favorite supported language (currently Java, Node.js, Swift, Python) that run in relevant runtimes within Docker containers launched for the short time needed.

OpenWhisk uses containers–which accelerate instantiation, deployment, and management–to support a trigger-based automation of  actions (individually or as a sequence) that can powerfully drive the real-time workflow of cloud-native mobile applications. An open API enables creating the packages (event producers and consumers) on which the application automation is built.

Users of OpenWhisk pay only for compute services used during the execution of actions. Currently, as in the experimental offering, the Beta is free to use in Bluemix, but with increases in computing limits that support bigger workloads.

What’s new in Beta as compared to the initial experimental launch? Highlights include:

  • Programming language support for Node 6, Python, and Swift 3
  • An improved model for using your own Docker containers as OpenWhisk actions
  • A browser-based interface for creating, editing, monitoring, and configuring actions, sequence, and integrations
  • A CLI that is easier to install
  • Event packages/providers for Cloudant, Github, IBM Push Notifications
  • Ready-made actions for Bluemix services: Cloudant, Weather Company Data for IBM Bluemix, IBM Watson, Slack, IBM Push Notifications, and web sockets
  • Downloadable SDK and sample iOS applications
  • A growing repository of open source applications in Github, including Dark Vision and Skylink

The OpenWhisk source code base is open source. It’s hosted on github.com actively under development.

Deploying a React web app with IBM Container Services

The IBM NodeJS team has built a starter for developers to quickly create and deploy a MERN stack in a Kubernetes container. You may ask, “What is a MERN stack?” MERN stands for MongoDB, Express, React and NodeJS. Our MERN starter is a working application with a React frontend that makes HTTP requests to an Express/Node.js backend, where sessions are persisted using MongoDB.
