What does FaaS mean?
FaaS in the Open-‐source World
FaaS frameworks for Kubernetes
Pros & Cons of “On-‐premises” FaaS
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)
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

IniOally developed by IBM
FaaS component of IBM Bluemix
Doesn’t run on Kubernetes yet (open issue)

Kubeless by Skippbox
FunkOon by Fabric8

Kubeless
clda.co/faas-‐kubernetes
“Only” a POC (wriaen in Go)
Both HTTP and PubSub
Based on Zookeeper and Kada+
Funk;on

@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+)

Fission

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…
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)
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 & monitoringPermissions & auth, orchestraOon
More naOve triggers (storage, db, streams) OperaOonal complexity
Addi;onal Resources
