4. clda.co/faas-­‐kubernetes What  does  FaaS  mean?
5. Func;on  as  a  Service clda.co/faas-­‐kubernetes h"ps://en.wikipedia.org/wiki/Func5on_as_a_Service Core  component  of  Serverless   No  infrastructure  management Microservices  approach FuncOon  as  the  unit  of  delivery MulO-­‐language  support  (BYOC) Transparent  scaling  (PAYG)
6. How  do  you  FaaS? clda.co/faas-­‐kubernetes Independent  FuncOons Versioning  &  Staging Cross-­‐team  CollaboraOon Triggers/Events Local  unit  tesOng IntegraOon  tests Automated  Workflow CI/CD
7. clda.co/faas-­‐kubernetes FaaS  in  the  Open-­‐source  World
8. Open-­‐source  FaaS clda.co/faas-­‐kubernetes openwhisk.org open.iron.io github.com/bfirsh/funker Apache OpenWhisk Funker IronFunctions
9. Open-­‐source  FaaS  -­‐  OpenWhisk clda.co/faas-­‐kubernetes openwhisk.org Apache OpenWhisk github.com/openwhisk/openwhisk/issues/1402 IniOally  developed  by  IBM FaaS  component  of  IBM  Bluemix Doesn’t  run  on  Kubernetes  yet  (open  issue) cloudacademy.com/blog/ibm-bluemix
10. github.com/bfirsh/funker Open-­‐source  FaaS  -­‐  Funker clda.co/faas-­‐kubernetes Funker Developed  by  @bfirsh Based  on  Docker  Swarm Support  for  Node,  Python  and  Go cloudacademy.com/blog/docker

12. clda.co/faas-­‐kubernetes FaaS  frameworks  for  Kubernetes
13. FaaS  on  Kubernetes clda.co/faas-­‐kubernetes Kubeless  by  Skippbox FunkOon  by  Fabric8 Fission  by  Pla_orm9
14. Kubeless clda.co/faas-­‐kubernetes “Only”  a  POC  (wriaen  in  Go) Both  HTTP  and  PubSub Based  on  Zookeeper  and  Kada +
15. Kubeless  Example clda.co/faas-­‐kubernetes
16. Funk;on clda.co/faas-­‐kubernetes @funk;onio funktion.fabric8.io Backed  by  Red  Hat  (wriaen  in  Go) Integrated  with  fabric8’s  Developer  Pla_orm Only  Python  is  supported Based  on  connectors  (200+) camel.apache.org/components
17. Funk;on  Example clda.co/faas-­‐kubernetes
18. Fission clda.co/faas-­‐kubernetes @fissionio fission.io Extensible  and  Fast  by  design  (wriaen  in  Go) Reduced  cold  starts  (warm  pool) Only  HTTP  triggers  for  now,  but… Only  Node  and  Python  for  now,  but…
19. Fission  Example clda.co/faas-­‐kubernetes
20. clda.co/faas-­‐kubernetes Pros  &  Cons  of  “On-­‐premises”  FaaS
21. Pros  of  “On-­‐premises”  FaaS clda.co/faas-­‐kubernetes Kubernetes  abstracOon  for  devs Open-­‐source  soluOon Fewer  non-­‐funcOonal  limitaOons More  control  over  infrastructure Might  be  cheaper  overall Might  be  faster  (dedicated  cluster)
22. Cons  of  “On-­‐premises”  FaaS clda.co/faas-­‐kubernetes Many  missing  features Versioning,  staging,  env.  vars,  Omeouts TesOng,  monitoring,  logging Responsibility  &  Ownership Provisioning  &  configuraOon UpOme  &  monitoring Permissions  &  auth,  orchestraOon More  naOve  triggers  (storage,  db,  streams) OperaOonal  complexity
