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)

FaaS on Kubernetes

Kubeless by Skippbox
FunkOon by Fabric8
Fission by Pla_orm9
Kubeless
clda.co/faas-‐kubernetes
“Only” a POC (wriaen in Go)
Both HTTP and PubSub
Based on Zookeeper and Kada+
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+)

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…
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
