Voxxed Days Microservices 2018
from Monday 29 October to Wednesday 31 October 2018.
Katherine Stanley is a Software Engineer in the IBM Messaging team based in the UK. She works on enterprise Kafka applications and specializes in microservices architectures. She has co-authored an IBM Redbook on Java microservices and has created samples to demonstrate industry best practices. She also works on the open source microservice project Game On. Katherine has given workshops and presentations at various conferences, including JavaOne in San Francisco, DevoxxUK and OSCON in London and JFokus in Sweden.
Apache Kafka is a very popular choice publish/subscribe messaging and event streaming in modern Cloud Native application. These reactive and event-driven applications are increasingly containerised and deployed to Kubernetes. This session will cover the practical aspects of deploying Kafka to a Kubernetes environment, from configuring resources to deploying applications.
We will show an example deployment of Kafka on Kubernetes, including the Kubernetes objects to use and the resource considerations you must make when configuring your deployment. The session will highlight useful metrics to consider when creating Kubernetes health checks and pitfalls to avoid.
Finally we will demonstrate how to connect an application to your Kafka deployment. This will include the additional objects required to expose Kafka to applications running externally to your Kubernetes cluster.
Istio is an open platform which aims to provide a uniform way to connect, manage and secure microservices. However, these are capabilities that are already provided by a variety of programming frameworks, such as Netflix OSS and MicroProfile fault tolerance. Can a platform really know everything about an application, or does the application sometimes know better?
This session will start with an introduction to the Istio architecture, including the sidecar model and what it means to deploy your application in this way. We will cover the technologies that overlap with existing framework capabilities such as security and fault tolerance. The differences between the approaches will be highlighted, including when to use which and how you can make them work in harmony together.
Istio also provides capabilities that compliment existing microservice and cloud native architectures. We will cover some of these functions, such as smart routing to enable A/B testing and canary deployments, together with how to make use of them within this new platform.
