Using Libvirt with Cluster API to Manage Baremetal Kubernetes - Giri Kuncoro & Himani Agrawal, GOJEK
There are many different tools available to bootstrap and manage Kubernetes cluster within various platform, but they don't all interoperate. Cluster API project attempts to solve this issue, which creates common declarative API, tools, and best practices for deploying, configuring, and managing Kubernetes in multiple platforms. It supports many public cloud provider plugins, and on-premise with vSphere and OpenStack.

However, running Cluster API for raw baremetal KVM machines without IaaS vendor remains a challenge. In this talk, we will show you how we use and configure Libvirt to create custom provider for Cluster API. Libvirt is an open-source API and management tool widely used for managing various virtualization platform. This enables us to manage Kubernetes on baremetal KVM/Qemu machines easily, with extensibility to run in Xen and other platform not supported by Cluster API.

Using Service Catalog Namespaced Resources to Personalize Your Service Offerings - Jonathan Berkhahn, IBM
Service Catalog is the Kubernetes implementation of the Open Service Broker API. Namespaced resources are a newly introduced feature that allow Kubernetes operators and users to more tightly control how OSB services are added to the platform and who can see and utilize those services. In addition, it allows normal app developers to add and utilize OSB brokers without the need for an operator to configure the cluster for them. In this take I'll go over how Service Catalog uses OSB to easily provision cloud infrastructure for cloud native apps running on Kubernets, how to use namespaced resources in Service Catalog as both an operator and a normal user, and demo using namespaced resources to provision services and use them with your application.

Build an Event Driven AI and Machine Learning Pipeline on Kubernetes - Yasushi Osonoi, IBM
AIOps as a field is becoming the need of the hour. With various Machine Learning capabilities coming in different open source projects, and pipelines being built, having a transparent AI pipeline which can notify users of any data drift, bias detection, model accuracy loss etc. is becoming key. In addition, we need capabilities to build a Data Scientists code from source, orchestrate the code, and automate the pipeline.

In this talk we will leverage Kubernetes components like build, eventing, serving and pipelines to show how to build an end to end AI pipeline which we detect any events happening, notify and take actions, can build and run data scientists code, do A/B testing, dark launch, and orchestrate the whole workflow from Model training, validation, serving, and operations. We will focus primarily on eventing and pipeline CRDs from Kubernetes to show this can be automated.

From Containers to Machine Learning: How Cloud Drives Open Source - Ian Lewis, Google
When Cloud platforms started to become popular, it was said that "Cloud will eat Open Source" because of the proprietary nature of Cloud systems. However, with the right approach, Cloud and Open Source help improve each other and grow together.

With projects like Kubernetes, Istio, TensorFlow, and more, Google Cloud has helped redefine Cloud as a platform based on open-source technologies with a commitment to sponsor projects with developer time. With projects like Docker, Google has helped drive open standards for containers, allowing for the growth of container runtime technologies like gVisor. This talk will take attendees through Google Cloud's commitment to open-source with a particular focus on containers & machine learning, and how open technologies like Kubernetes, Istio, gVisor, and TensorFlow are changing the landscape to one where Cloud and Open Source live and grow together.

Extensibility and Possibility of Kubernetes Custom Resource - Masaya Aoyama, CyberAgent, Inc
Kubernetes is implemented some resources (eg. Deployment, Service and ConfigMap).
The basic resources is used for general purpose, but we need specific resources in each own domain.
For example, if developers build MySQL cluster with basic resources, startup scripts will be so complex. But the MySQL custom resource with simply manifest will make MySQL cluster as managed Database services.

Kubernetes is not only for container platform, but Kubernetes is also a framework for applications using kubebuilder, Operator SDK and so on.At the CyberAgent, we implement GPUaaS resources and some application cluster resources for sophisticated application management.

In this talk, attendees will learn about how to implement own custom resources and the controller, and I will talk about the possibility and extensibility of kubernetes.

Bridging, not Breaking Tradition: Use Service Mesh Expansion to Connect Legacy Workloads to Kubernetes Services - Steven Wong, VMware
Kubernetes has become a preferred platform for hosting distributed and portable services and applications. With this, Istio service mesh can be deployed to address service discovery, service-to-service authentication and encryption, traffic management, metrics, monitoring, and more.

The practice of using a service mesh within a Kubernetes cluster is well known, but what if you want to integrate new services with legacy?

This session will show how to use a technique called mesh expansion to achieve interoperation of applications and services, split across Kubernetes and traditional VM or bare metal hosts.

Specific examples will demonstrate how to:
- Send requests from VM workloads to Kubernetes services
- Run services on a VM that is part of a mesh expansion

Cloud Native CI/CD with Tekton Pipelines and Knative - Andrea Frittoli, IBM
Cloud-native developers can enjoy a rich ecosystem, with plenty of functionality already available from existing microservices, a service mesh or the cloud fabric. These benefits come at the cost of added complexity in the development workflow: a could native application is made of a potentially large number of components, and verifying and troubleshooting a small change in one of them might prove challenging. Automation, in the local development environment as well as in the form of continuous integration and delivery pipelines, is fundamental to reduce complexity. In this talk I will introduce Tekton pipelines and Knative; I will present my experience combining the two projects to build cloud-native continuous delivery pipelines. I will discuss the challenges and benefits of using the building blocks of the CD pipeline to implement CI and enhance the development workflow as well.

Building a Scalable Data Science & Machine Learning Cloud Using Kubernetes -Murali Paluru, Rancher Labs, Inc.
Tagline: A real-life story of architecting & building a cloud-native data science platform using Kubernetes.

A growing team of data scientists was looking for a simple, flexible, scalable and a secure way of migrating to the cloud as the on-prem data center started becoming a bottleneck. Kubernetes, which enables applications to run on a variety of private and public clouds, along with an ever-growing feature set, matched most of the team's requirements.

In this talk, Murali Paluru, who had the opportunity to work with the Data Scientists team, will share the gathered requirements, architecture and in-depth details of the Data Science platform built on top of Kubernetes. He will also demo a one-click solution that he has developed, to hide away the complexity of Kubernetes and enable the Data Scientists to focus on analyzing the data instead of managing the underlying infrastructure.

A Deep Dive into the Performance of Istio - Shukun Song & Yushiro Furukawa, Fujitsu Limited
As a microservice application grows in size and complexity, the behavior of its network can become harder to be understood and managed.

To solve such complex management problem, Istio, a project which provides lots of network key features such as load balancing, monitoring, security and so on to microservice applications, has been developed. It can significantly ease the strain on development teams.

However, although Istio has become ready for production since V1.0, utilization of Istio may not be appropriate for enterprise applications in which high performance is required, as Istio can cause additional network latency.

In this presentation, Shukun SONG will explain where the bottleneck of Istio is by profiling its action. And he will also introduce a solution idea which is based on deploying Mixer as daemonset and use data to show the effect this idea can bring.
