Lightning Talk: A Brisk Introduction and Demo of KEDA - Kubernetes Event Driven Autoscaling - Sagar Joshi, Microsoft
KEDA (Kubernetes Event Driven Autoscaling) an opensource framework developed by Microsoft and Redhat which enables Kubernetes workloads (Pods) to scale according to events. The built-in HPA (Horizontal Pod Auoscaler) of Kubernetes scales according to CPU/memory of pods but autoscaling with custom events like queue length or number of events or other metrics requires large amount of coding and deep knowledge of operators. KEDA framework supports autoscaling pods with a variety of event-driven systems like Kafka topics, Redis cache, Prometheus metrics and many Cloud-based service-based messaging service. In this session we will see architecture of KEDA and a demo of POD autoscaling through one of Cloud-based messaging services.

KEDA can be paired with Virtual Kubelet to implement Serverless scaling scenarios,

Lightning Talk: From PaaS to FaaS : Managing Serverless on Kubernetes - Suman Chakraborty, SAP Labs, India
Call it “serverless,” call it “event-driven compute” or call it “functions as a service (FaaS),” the idea is the same, allocate memory dynamically to event-driven functions to built microservices. Serverless computing platform allow developers to focus in building the application logic while abstracting away the infrastructure requirements and management details.

Many serverless offering from cloud-managed providers restrict the behavior of app logic that they run, sometimes making certain classes of applications impractical. Kubernetes has been the de-facto open source management platform for running applications in containers through a well-orchestrated tooling mechanism, taking care of the scalability, rolling updates, self-healing and load-balancing processes.
In this context, Suman Chakraborty will explain the major advantages Kubernetes provides in running serverless frameworks, the major open source projects that brings serverless functionality in Kubernetes and the challenges that has been reported by consumers in adopting Serverless frameworks in recent times.

Fast Execution for Function Compositions in Serverless Computing - Ruichuan Chen & Istemi Ekin Akkus, Nokia Bell Labs
Serverless computing has rapidly gained traction with its promise of continuous scaling and low costs without the hassle of managing servers. Though it was originally aimed for running single functions, developers have embraced it to compose scalable applications with multiple interacting functions. However, many platforms map individual functions of an application into their own containers and require them to be stateless. This creates the biggest downside of serverless computing: serverless applications suffer high performance penalties from long invocation delays among functions and slow access to externalized application state. In this presentation, Ruichuan and Ekin revisit these design choices and propose an alternative with KNIX: grouping an application’s functions in the same container as separate processes while isolating different applications in different containers. Coupled with process forking and locality mechanisms, this design allows function executions to start and interact about an order of magnitude faster compared to current serverless platforms. In addition, it examines the use of stateful, addressable function executions for fast access to application state.
