  1. Serverless Architectures Meetup HonG Kong May 2018 Dr. Frank Munz

    munz & more
  2. • Founded munz & more in 2007 • > 15

    years Middleware, Multi Cloud, and Distributed Computing • Consulting and High-End Training • Wrote two WebLogic and a Cloud book Dr. Frank Munz @frankmunz
  3. Agenda • Cloud • The Serverless Journey • FaaS •

    Fn Project • Q&A @frankmunz
  4. Clouds!

  5. API @frankmunz

  6. Elasticity

  7. Pay Per Use • ~1 US cent/h (micro instance), with

    HA & geo-distribution included • You own a massively parallel, distributed and highly available supercomputer with linear costs: 1 instance for 100 hours $= 100 instances for 1h @frankmunz
  8. Cloud Computing API Elasticity Pay per use Fully Programmable Data

    Center
  9. Serverless

  10. FaaS

  11. FaaS • AWS announced Lambda in 2014 • Lambda is

    Function as a Service (FaaS) • Serverless: Abstract away all notion of infrastructure – Automated elasticity – True pay per invocation • Other serverless examples: Messaging, DBs, blob storage -> Future of cloud @frankmunz
  12. AWS Lambda AWS SAM Local: test and locally run Lambda

    event: event passed to function context: runtime context callback: optional return (or null) @frankmunz
  13. Create Lambda S3 @frankmunz

  14. Example: REST Request

  15. Cost Savings: Case Studies Expedia(2016): – 2.3 billions calls –

    200k hours / month – $ 550 a month Postlight – API GW, Lambda, Serverless – Costs dropped 2 orders of magnitude down to $ 370 https://www.youtube.com/watch?v=gT9x9LnU_rE https://trackchanges.postlight.com/serving-39-million-requests-for-370-month-or-how-we-reduced-our-hosting-costs-by-two-orders-of-edc30a9a88cd http://serverlesscalc.com/ @frankmunz
  16. Frameworks

  17. Serverless Frameworks @frankmunz AWS Chalice Portability Complexity Standards

  18. OS FaaS Platforms

  19. FaaS OS Frameworks Overlap in functionality -> expect consolidation Who

    will survive? • Integration: K8s, Traefik, Zipkin, Prometheus, Kafka etc. • Adoption, adoption, adoption • FaaS as PaaS implementation? https://github.com/faas-lane/ FaaS-Lane/tree/master/candidates @frankmunz
  20. Fn Project • Apache 2, Open Source since Java One

    2017 • Fn Server (micro API GW), LB, Flow • Function / Container duality • Docker is only dependency -> polyglot • Helm chart for Kubernetes @frankmunz
  21. KubeCon • Brand new as of May 2nd, 2018 •

    Fn is adding support for Cloud Events • You can deploy Fn functions with Serverless.com framework @frankmunz
  22. Fn Flow Java 8 CompletableFutures API

  23. Fn Demo?

  24. None
  25. Recomendation Engine Mock Demo? https://github.com/fmunz/fn-recommend

  26. Demo: FaaS Bot?

  27. Conclusion

  28. TL;DR #serverless & #FaaS all major clouds / PaaS ⊇

    Serverless ⊇ FaaS / FaaS = stateless / true pay per use / automated scalability / event driven / integrates with other CS / architect against vendor lock in / cloud agnostic FaaS frameworks / FaaS frameworks consolidation ahead / Fn is growing + tightly integrated into CNCF @frankmunz
