"On-premises" FaaS on Kubernetes
- 2. About Me @alex_casalboni clda.co/faas-‐kubernetes Bachelor in Computer Science Master in Sound & Music Engineering SoBware Engineer & Web Developer Cloud Evangelist @ Cloud Academy
- 3. Agenda clda.co/faas-‐kubernetes What does FaaS mean? FaaS in the Open-‐source World FaaS frameworks for Kubernetes Pros & Cons of “On-‐premises” FaaS
- 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

- 8. Open-‐source FaaS clda.co/faas-‐kubernetes openwhisk.org open.iron.iogithub.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

- 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 +
- 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
- 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…
- 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
