Cloud Ready JVM with Kubernetes

Congratulations, you are done coding, you made a runnable Jar file. So what? How does it go into the cloud?

In this talk we will explore how JVM applications can be packaged inside a Docker image and discuss tips and common pitfalls. We will continue with a brief introduction to Kubernetes, how it can help deploy our Docker containers & how it can integrate with frameworks like Spring. Finally, will look at a development workflow which allows fast local development of large microservices applications leveraging Telepresence.
Novice & competent Kubernetes users welcome!

Deploying and scaling Spring Boot microservices to Kubernetes

When you design and build applications at scale, you deal with two significant challenges: scalability & robustness. You should design your service so that even if it is subject to intermittent heavy loads, it continues to operate reliably. But how do you build such applications? And how do you deploy an application that scales dynamically? Kubernetes has a feature called autoscaler where instances of your applications are increased or decreased automatically based on metrics that you define.

In this talk, you’ll learn how to design, package & deploy reliable Spring Boot applications to Kubernetes & decouple several components using a message broker. You will also learn how to set autoscaling rules to cope with an increasing influx of messages in the queue.

From Kubelet to Istio: Kubernetes Network Security Demystified

Kubernetes provides multiple layers of network security including the control plane, etcd, the CNI network, network policies, & - with Istio on top - the requests between applications themselves. In this talk we explore the underlying technologies on which these layers are built using approachable examples & demonstrations. Attendees can expect to gain an understanding of these implementations & the principles behind encryption, identity, & trust in Kubernetes.

Speaker Bios

Being a Java developer for many years, Cesar Tron-Lozai was very excited when Java 8 came out, and the functional elements it brought to Java. His interest didn't stop there and he went to play with Scala, Haskell, and eventually study Category Theory (the mother of all theory that is behind functional programming). In his job as Head of Engineering of a small startup, he gets involved with all the aspects of software development: Infrastructure, DevOps, design, backend and frontend. In his spare time he co-organise Devoxx4kids in the UK.

Daniele Polencic is a technical consultant at https://learnk8s.io/ and a certified Kubernetes administrator and authorised trainer partner for Kubernetes and the Linux Foundation. He’s passionate about solving problems and programming, particularly in JavaScript. In the last decade, Daniele has trained developers for companies in e-commerce, finance and the public sector. When he isn’t writing code, he advises startups in the London tech scene.

Andrew Martin has a strong test-first engineering ethos gained architecting and deploying high-traffic web applications. Proficient in systems development, testing, and maintenance, he is comfortable profiling and securing every tier of a bare metal or cloud native application, and has battle-hardened experience delivering containerised solutions to enterprise clients. He is a co-founder at https://control-plane.io.
