We will tell you about…

● Why we need event-driven infrastructure

● Requirements for event-driven infrastructure

● Introducing OpenWhisk

● OpenWhisk and CloudFoundry

● Demo

Welcome to Industrial internet!

Devices can be...

How would you implement it?

OK, let’s move step by step

And if you want it to be HA?

What about another device?

Let’s be smart!

An unexpected spike!

Scaling out!

And traffic goes down...

An excessive compute?

Or maybe those ones?

And in the meantime...

And further down...

And...

One process, one container

But if we don’t scale fast...

How much does it cost?

Ideal case

Compute follows traffic

So what are the requirements?

● Invoke and scale as fast as possible● Terminate after completion

● Invoke and scale as fast as possible● Terminate after completion● Charge per compute used

● Invoke and scale as fast as possible● Terminate after completion● Charge per compute used● Guaranteed message delivery● Load balancing

● Invoke and scale as fast as possible● Terminate after completion● Charge per compute used● Guaranteed message delivery● Load balancing● High availability● Self-healing

● Support of multiple technologies

● Have possibility to launch other microservices

● Write and read data from multiple data sources

● Support of multiple technologies

● Have possibility to launch other microservices

● Write and read data from multiple data sources

● Abstract developers from the infrastructure

Serverless computing in general and OpenWhisk in particular is regarded an important effort 31

Serverless deployment & operations model

Optimal utilization & granular pricing

Scales on a per-request basis

Flexible programming model

Supports higher-level programming constructs (e.g. sequencing)

Polyglot support

Variety of languages

• Services define the events they emit as triggers, and developers associate the actions to handle the events via rules

• The developer only needs to care about implementing the desired application logic - the system handles the rest

Trigger: „A class of events that can happen“T

A Actions: „An event-handler, i.e. code that runs in response to an event“

AA:= A1

+ A2+ A3

AB:= A2

+ A1+ A3

AC:= A3

+ A1+ A2

Actions: Can be chained to create sequences to increase flexibility and foster reuse

R := T A

Rules: „An association of a trigger and an action“

myActionmyFeedT

Packages: „A shared collection of triggers and actions“P

Cloud Foundry and OpenWhisk

I can’t use OpenWhisk on Bluemix because

Vendor lock-in

Vendor lock-inAll my data is (in local datacenter)

We implement a hybrid strategy

We don’t use Bluemix at...

I need to have the compute device on the network edge
