- 2. IBM Bluemix OpenWhisk@DanielKrook Increasingfocusonbusinesslogic Decreasing concern (and control) over stack implementation Bare Metal VM VM VM Virtual machines Functions Containers Serverless developers focus more on code, less on infrastructure
- 3. IBM Bluemix OpenWhisk@DanielKrook Monolithic Application Break-down into microservices Make each microservice HA Protect against regional outage Region A Region B Microservices can be hard to manage at scale
- 4. IBM Bluemix OpenWhisk@DanielKrook Emerging workloads are a good fit for event-driven programming Execute logic in response to database change Perform analytics on sensor input messages Provide cognitive computing via chatbots Schedule tasks performed for a short time Invoke autoscaled APIs and mobile backends
- 5. IBM Bluemix OpenWhisk@DanielKrook Memory allocated (MB) Time executing (milliseconds) Instances executing simultaneously (count) Cloud resource cost better matches business value gained Not a silver bullet, but this can result in substantial savings for many workloads New cost models more accurately charge for usage
- 6. IBM Bluemix OpenWhisk@DanielKrook OpenWhisk is a cloud platform that executes code in response to events OpenWhisk enables these serverless, event-driven workloads Provides serverless deployment and operations model Runs code only on-demand on a per-request basis Optimized utilization, fine-grained metering at any scale Flexible, extensible, polyglot programming model Open source and open ecosystem (Apache Incubator) Ability to run in public, private, and hybrid models
- 7. IBM Bluemix OpenWhisk@DanielKrook Results Developers work with packages, triggers, actions, and rules Package (feed) Packages provide integration with external event sources P Trigger (event) T Data sources define events they emit as Triggers Rule (map)R Action (function) A Developers map Actions to Triggers via Rules
