OpenWhisk is an open-source serverless platform ideally suited to a wide range of scenarios including cognitive, data, IoT, microservices, and mobile workloads. Since we presented OpenWhisk at ServerlessConf London a lot has happened. It has been successfully accepted as an Apache Incubator project and the first production OpenWhisk deployments have happened. From a technical point of view we have added capabilities like a better API Gateway integration and support for web actions, have added integrations with IBM App Connect, IBM Message Hub, and more. During this talk we will discuss our latest additions and illustrate how to benefit by “going” serverless with OpenWhisk by exploring some real-world customer usecases with a focus on how serverless architectures can be exploited in totally different scenarios. Using these usecases we will explain how OpenWhisk works and why it is the ideally platform for these emerging workloads. After the talk we will be looking forward to discussing your own usecases in more detail at our booth.

Vehicle Dispatch
PubNub Blocks → OpenWhisk
PubNub Blocks filters geo data and
routes to OpenWhisk for
computation. OpenWhisk runs
business logic and M.L. and
broadcasts back to PubNub
listeners on end-devices.
NewSample use-cases…
Disaster Alerts
OpenWhisk → PubNub
OpenWhisk detects weather
anomalies and and broadcasts to
PubNub listeners on end-devices
for real-time disaster alerts.
Social Chat App
PubNub → Watson + OpenWhisk
PubNub filters chat messages
through a PubNub Watson
Translator Block, and offloads
audience analysis to OpenWhisk for
async post-processing.
