The Fn project is an open-source container-native serverless platform that you can run anywhere -- any cloud or on-premise. It’s easy to use, supports every programming language, and is extensible and performant. https://fnproject.io/

5. Way too many problems ….
• Monolithic Apps
• Slow deployment times
• Huge Costs
• Wasted Resources
• Difficult to Scale
• Difficult to migrate
• Vendor Lock in

7. Better but still limited….
• Each VM still requires
CPU allocation,
storage, RAM,
An entire Guest OS
• Guest OS à Wasted resources
• Application tied to the OS, multiple instances of application need multiple VMs
• More VMs à More resources

9. Containers are everywhere...
• Portable and efficient
• No dependencies on the kernel or the Hardware
• Can run on baremetal or VMs
• Applications packaged in a container speeds deployment (CI/CD)
• Provides a path for micro-services application architecture

11. Serverless .. (sort off..)
• You don’t have to “think” about infrastructure
• You are not responsible for:
• Turning infrastructure on/off
• Scaling infrastructure up/down
• Monitoring infrastructure
• As a result:
• You are more productive (faster feedback loop)
• You only pay for actual usage, not for idle time
• Unit of deployment is a Function ..

13. A serverless platform key properties..
• Open Source - no vendor lock-in
• Platform Independent - laptop, server, cloud
• Approachable - easy for new users, low level controls for advanced users
• Container/Docker Based - leverage Docker ecosystem
• Scheduler/orchestrator Independent - deploy to Kubernetes, Swarm, Mesos, etc.

15. Introducing the Fn Project
● Open-source Functions platform
● Can be deployed to any cloud and on-premise
● Simple, elegant, and extensible by design
● Containers are primitives
● Active 3200+ commits across 60+ contributors
● Independently governed with representation at Container Native Compute Foundation (CNCF)
● Strong enterprise focus (security, scalability, observability, etc.)

16. Functions == Containers
Functions are packaged as containers—so any
container can be deployed as a function
Package and reuse open source libraries as
functions!

21. Function Development Kits (FDKs)
Simply write a `handler` function that adheres to the FDK’s interface and the FDK will provide
the input to your function, as well as deal with returning the proper output format.
FDKs make it easy to write functions
