- 3. Agenda • Whisk in a nutshell • Meet Dave & his team • Learn about... – …what OpenWhisk is and how it works – …the value of OpenWhisk and how it compares to traditional models – …what makes OpenWhisk so unique • Learn about some usage scenarios • Learn about the OpenWhisk programming model • Live demo • Summary & Questions 3
- 4. Whisk in a nutshell „Event-action platform to execute code in response to events“
- 5. Whisk in a nutshell Serverless deployment & operations model We hide infrastructural and operational complexity allowing you to focus on coding: You provide code – we execute it! Optimal utilization, fair pricing at any scale We provide you exactly with the resources you need – neither less nor more - and charge you only for code really being executed Flexible programming model & powerful tooling We support multiple languages (incl. Swift) and even the execution of custom logic via docker containers plus tools to declaratively chain your code snippets Open & open ecosysten Open to run anywhere to avoid any kind of vendor lock-in and to accelerate the development of a powerful ecosystem
- 6. Meet Dave & his team • Dave is lead architect of an online photo community and marketplace – Operate a platform to… • … share and sell photos • … edit and categorize photos via manual tagging 6
- 7. Meet Dave & his team • To remain competitive, Dave and his team need to continously add innovative features – Idea • Provide a mobile app that allows to automatically sharpen, noise-reduce and semantically analyze photos being uploaded 7
- 8. Meet Dave & his team • Dave & his team start to collect requirements… – Want to focus on developing value-adding code instead of low- level infrastructural & operational details
- 9. Meet Dave & his team • Dave & his team start to collect requirements… – Want a flexible programming environment and model in order to develop services in small & agile teams whereas each team can stick to the technology it knows and loves instead of going for a one size fits it all approach
- 10. Meet Dave & his team • Dave & his team start to collect requirements… – Need access to an open ecosystem of building blocks from multiple domains and vendors to easily integrate existing technologies to avoid reinventing the wheel over and over again
- 11. Meet Dave & his team • Dave & his team start to collect requirements… – Want to be able to compose powerful solutions by connecting and even chaining these building blocks rather than continously changing code
- 12. Meet Dave & his team • Dave & his team start to collect requirements… – Want to share and reuse created compositions (and other entities) instead of causing redundancy
- 13. Meet Dave & his team • Dave & his team start to collect requirements… – Want to be able to outsource compute intensive tasks to a powerful cloud platform
- 14. Meet Dave & his team • Dave & his team start to collect requirements… – Want to be charged for code executed instead of paying for resources idling around
- 15. Meet Dave & his team • Dave & his team start to collect requirements… – Want to go with an open solution driven by a community to remain flexible instead of vendor locked-in
- 16. OpenWhisk: Another way to build apps… Build your apps, your way. Use a combination of the most prominent open-source compute technologies to power your apps. Then, let Bluemix handle the rest. Ease of getting started Full stack Control OpenWhisk Event-driven apps, deployed in a serverless environment. Instant Runtimes App-centric runtime environments based on Cloud Foundry. IBM Containers Portable and consistent delivery of your app without having to manage an OS. Virtual Machines Get the most flexibility and control over your environment with VMs.

- 19. OpenWhisk: Comparison to traditional models Swift Application Container VMCF 22 Polling 1b1b Request 1a1a • Traditional model – Continous polling due to missing event programming model – Charged even when idling – No auto-scaling Process & idle
- 20. OpenWhisk: Comparison to traditional models • OpenWhisk – Introduces event programming model – Charges only for what is used – Auto-scales Pool of actions Swift DockerJS Trigger 11 Running action Running action Running action 33 Deploy action within millisecs, run it, free up resources OpenWhisk Engine 22
- 21. Some usage Scenarios OpenWhisk can help power various mobile, web and IoT app usecases by simplifying the programming model of orchestrating various services using events without a dedicated backend. Digital app workloads Big Data/Analytics pipeline Complex data pipeline for Big Data/Analytics tasks can be scripted using changes in data services or streams for near real-time analytics and feedback. DevOps & infrastructure as code OpenWhisk can be used to automate DevOps pipeline based on events triggered from successful builds or completed staging or a go-live event. Micro-Services builder Whisk can be used to easily build micro-services given the footprint and programming model desired by micro services
- 22. Programming model • 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 TT AA RR
- 23. Programming model Trigger: „A class of events that can happen“TT
- 24. Programming model Actions: „An event-handler, i.e. code that runs in response to an event“AA
- 25. Programming model Actions: Multi-runtime support, e.g. JavaScriptAA function main(msg) { return { message: 'Hello, ' + msg.name + ' from ' + msg.place }; };
- 26. Programming model Actions: Multi-runtime support, e.g. SwiftAA func main(params:[String:Any]) -> [String:Any] { var reply = [String:Any] () if let name = params[“name”] as? String { print(“Hello (name)”) reply[“msg”] = “Goodbye (name)” } return reply }
- 27. Programming model Actions: Multi-runtime support, e.g. Docker containersAA
- 28. Programming model Actions: Can be chained to create sequences to increase flexibility and foster reuse AA AA AA := A1 A1 + A2 A2 + A3 A3 AB AB := A2 A2 + A1 A1 + A3 A3 AC AC := A3 A3 + A1 A1 + A2 A2

- 32. Summary • OpenWhisk… – allows you to focus on developing value-adding code – provides you with a flexible programming model for small agile teams – provides you with access to an open ecosystem of building blocks – allows you to compose powerful solutions using modern abstraction and chaining – allows you to share and reuse what you have build – allows you to outsource load & calculation intensive tasks – only charges you for what you really use – is available as open solution in which you can participate
- 33. Summary • What else have we seen & learnt? – Actions are executed, blocking or non-blocking, in response to events – Actions can be in Node, Swift, or even Docker containers to execute custom logic… and there is more to come – Actions can even be chained to compose powerful solutions – Out of the box support for event sources such as Cloudant and Github as well as scheduled actions – Tooling comprised of CLI, REST API, and iOS SDK • What have we not seen? Complexity!
