Troubleshooting & Debugging Microservices in Kubernetes

Debugging applications in production is like being the detective in a crime movie. Especially with microservices. Especially with containers. Especially in the cloud. Trying to see what’s going on in a production deployment at scale is impossible without proper tools! Google has spent over a decade deploying containerized Java applications at unprecedented scale and the infrastructure and tools developed by Google have made it uniquely possible to manage, troubleshoot, and debug, at scale.

Join this session to see how you can diagnose and troubleshoot production issues w/ out of the box Kubernetes tools, as well as getting insight from the ecosystem with Weave Scope, JFrog Artifactory & Stackdriver tools.

A Craftsman’s Guide To Designing A Clean Architecture

In 2018, it seems like Microservices are the de facto standard for a system architecture, but do they really live up to the hype? The talk will show you an alternative approach – how we can tame complexity with the help of a clean, monolithic architecture that is modular to the core. Java has been deliberately built from the ground up on a modular basis: Methods, classes, packages. Additionally, the module system was introduced in Java 9.

Modularity is based on the fundamental concepts of high cohesion and low coupling. We will look at these concepts, as well as some further measures, in detail. We’ll check out what they are, how they are related to one another, and what the best practices are for applying them on all levels of the architecture. The talk will show you how you can apply these basic concepts to develop a clean, monolithic architecture, based on Java 9 modules and the hexagonal architecture pattern.

About The Speaker

Marcus Biel is a software craftsman and the author of a series of Java video tutorials focused on creating the cleanest and most well-structured code possible. As someone who has previously spoken in public about his ideas on Java development, and who continues to share his ideas, he prides himself on being a clean code craftsman who is always looking to help others with his knowledge and experience.

Since 2001, Marcus has worked on many different Java related projects, mostly in the finance and telecommunications industries. He considers himself a pragmatic perfectionist and looks to share his know-how with aspiring developers.

Despite his strictness with Java, he loves trying crazy things, probably because he gets bored very quickly. He enjoys nature and likes hiking in the Alps as well as backpacking. He has travelled all over the world including visits to Brazil, China, Australia, and the USA. He also enjoys dancing, a good beer or wine, and adventuring around Munich. Marcus lives in Munich, Germany, with his wife, within walking distance of the Oktoberfest, and yes, he owns Lederhosen.
