Request

•  Traditional model – Continous polling due to missing event programming

model – Charges even when idling due to poor utilization – Worry about scaling

•  When to scale? (mem-, cpu-, response time-driven) •  How fast to scale?

– Worry about resiliency •  At least 2 processes for HA (driving cost) •  Deployment in multiple regions (driving cost) •  Keep them running & healthy

Process & idle

Serverless: Comparison to traditional models

•  Serverless –  Introduces event programming model – Charges only for what is used due to optimal

utilization – Scales inherently

•  One process per request – No cost overhead for resiliency

•  No long running process for HA

OpenWhisk: How does it work? Coming soon...

•  API Gateway is build based on contributions from Adobe & IBM leveraging technologies like Nginx & IBM’s microgateway

•  Allows to create, run, manage and secure APIs and microservices •  Combined with OpenWhisk it provides an easy way to build

backends without the need to manage servers by mapping APIs to actions

•  Both technologies together allow to quickly develop & deploy serverless web & mobile applications

Incoming HTTP request, e.g. HTTP GET api-gw.mybluemix.net/…/getCustomers

-  API Gateway takes care of… -  security (authenticate, authorize, threat protect, validate)

-  control (rate limiting, response caching)

-  mediation

-  parameter mapping

-  schema validation

-  … and supports e.g. different verbs (Get, Post, Put, Delete, …)

Some usage Scenarios

•  Microservices-based apps / APIs

•  Mobile Backends

•  Data (Stream) Processing

•  IoT

•  Cognitive

•  Bots

Real-world customer scenario

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

Integration with 3rd party tools: Sample NodeRED

•  Community effort to integrate with open tools: NodeRED

•  NodeRED is all about automating flows to orchestrate calls to different service APIs –  Usually triggered by calls from external systems or devices –  Runs within a long-running single node process, with a dedicated amount of CPU & memory

being allocated

•  OpenWhisk is all about executing code (custom logic) in response to events on a scalable platform, with a dedicated amount of CPU & memory being allocated per-request

•  NodeRED and OpenWhisk complement each other –  Use NodeRED to graphically create flows, automating a series of tasks in a kind of workflow –  Use OpenWhisk to execute custom logic (requiring some kind of CPU- or memory bound

operation) triggered from within NodeRED

Integration with 3rd party tools: Sample VS Code

•  Community effort to integrate with open tools: VS Code extension

•  Eases development with OpenWhisk by supporting the entire development cycle (list, create, update, invoke, actions etc.) without the need to leave the IDE

•  Extension works for actions written in different languages (like JS and Swift) and on different platforms (like Windows, Mac, and Linux)
