State of Serverless [B] - Mark Peek, VMware & Doug Davis, IBM
Serverless and FaaS computing is gaining in popularity to easily create microservice applications. In this talk we will discuss what are the characteristics of serverless, the status of the serverless working group within the CNCF, and the open source options available for running serverless and associated services with a focus on kubernetes.

Building Serverless Application Pipelines [A] - Sebastien Goasguen, Bitnami
The serverless paradigm is bringing a new type of applications to the forefront of application architecture. Distributed, containerized, scalable, event-driven and ephemeral with fine grained billing. In this talk we will go through several application use-cases that are driving the serverless movement (e.g data processing, IoT, mobile-backends,machine learning) and demonstrate how these applications can be developed and deployed on top of Kubernetes using an open source serverless solution called kubeless. Through live demos and examples, we will show that Kubernetes with its rich and stable core API is the perfect platform to build FaaS solutions.

FaaS and Furious - 0 to Serverless in 60 Seconds, Anywhere - Alex Ellis, ADP

OpenFaaS (or Functions as a Service) is a Cloud Native framework for building serverless functions with containers (as popularised by AWS Lambda). With OpenFaaS you can package any process or container as a serverless function for either Linux or Windows - just bring your Kubernetes or Docker cluster. Avoid vendor lock-in by running functions in your own datacenter or the cloud with your existing CI/CD and container ecosystem. The project focuses on ease of use through its UI and CLI which can be used to test and monitor functions in tandem with Prometheus integration that enables auto-scaling as demand increases.

You can deploy OpenFaaS in 60 seconds on Kubernetes and thanks to concise code templates all you need to write is a handler in your favourite programming language then let your cluster do the heavy lifting.

OpenFaaS was recently trending as the top open-source project on GitHub, won Best Cloud Computing Software 2017 from InfoWorld and has a thriving community with 65 contributors, 1400 commits and over 8k stars.

Come and find out how and why people are leveraging an event-driven architecture along with some cool interactive demos and swag.

Note - OpenFaaS is an independent project started by Alex Ellis and is now being shaped by a growing community of contributors and users.

Fission: Serverless Functions for Kubernetes [B] - Soam Vasani, Platform9 Systems
"Serverless" functions allow users to easily create services from source code without dealing with packaging, deployment, scaling, etc.

Fission is a serverless function framework built on Kubernetes. Users write functions and map them to event sources, such as HTTP requests, timers, Kubernetes watches, and message queues. Users don't have to deal with container images, registries or even learn Kubernetes in much detail.

Functions consume CPU and memory resources only when running. Fission makes on-demand function loading very fast by keeping an idle pool of containers running, in effect creating a distributed "threadpool".

Fission is useful for:
* Creating web app backends or REST APIs
* Implementing webhooks
* Watching Kubernetes Resources for changes to implement simple custom
controllers
* Creating Kubernetes Initializers with minimal work

In this talk we'll give a few demos for these use cases, and cover:

* How fission works with function dependencies in a language-agnostic manner
* The development lifecycle of Functions: testing and incremental deployment
* The composition of functions into workflows using the Fission Workflow project
* Observability: log aggregation, metrics with Prometheus, tracing with Opentracing/Zipkin
* The interaction of functions with service meshes (Istio/Envoy)

Pontoon: An Enterprise Grade Serverless Framework Using Kubernetes – As Used in VMware Cloud Services [I] - Kumar Gaurav & Mageshwaran Rajendran, VMware
In VMware Cloud services, we perform both batch and real-time computations based on periodic schedules and on-demand events, using our in-house developed serverless framework called Pontoon. This provides better utilization of resources and enables our service developers to write serverless functions with simple declarations.
Kubernetes provides Jobs and Deployments as design constructs to handle such needs, while other frameworks like IronIO Functions, Fabric8, et al aim to solve end-to-end use case . However, we had to extend on top of Kubernetes Jobs & Deployments to define the packaging and I/O interactions of the function, implement a priority queue for execution, and provide declarative retry policy while ensuring high availability. A developer 'writes' a function supporting common EAI patterns for start time parameterized variables, and defines it's packaging and scheduling using a yaml file. The framework then packages it as a Container alongwith an 'observer' container in a pod, 'registers' it with the scheduler while ensuring choice of 'warm' vs on-demand requisite replicas of the pod, and then through a 'Scalar' manages the execution and life cycle of job, while logging and tracing failures/success.
This framework is in use over months in VMware Cloud services and we are now open sourcing it.

Building and Running an Enterprise-grade Serverless Platform on Kubernetes - Ying Huang & Quinton Hoole, Huawei
Serverless platforms provide functions as a service, and have become a hot topic largely because they allow developers to focus on core business logic, leaving packaging, deployment, monitoring, event propagation, scaling and load balancing to the infrastructure. The serverless billing model is simple - pay-per-invocation - which can being significant benefits for many event-driven applications.

Huawei launched its FunctionStage serverless platform, which is built on Kubernetes, in 2017. In this talk we will explain in detail the design and implementation of FunctionStage. This involved both fairly straightforward function packaging, scheduling, auto-scaling, event triggering and load balancing, as well as some significantly more interesting challenges related to container re-use, on-the-fly micro service provisioning, reliable operation and much more. We will demonstrate the use of our system to solve some complex real-world problems in Huawei Public Cloud.
