An Evening of Kubernetes Talks
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. This is a placeholder for the event being held on Eventbrite.

What we're about

The London Java Community (LJC) is a group of Java Enthusiasts who are interested in benefiting from shared knowledge in the industry. Through our forum and regular meetings you can keep in touch with the latest industry developments, learn new Java (& other JVM) technologies, meet other developers, discuss technical/non technical issues and network further throughout the Java Community.

What is the LJC?

The LJC is an official Java User Group for developers based in London. It was founded in November 2007 and since then has grown to over 5000 members and is now the biggest Java User Group in the UK.

What goes on in the LJC?

We run a variety of regular events ranging from social events and technical presentations to our full day unconference. On top of the events we run prize draws and have an active mailing list/forum. We support the Graduate Development Community in London and promote London based Open Source Software projects where possible.

Who can join?

Membership is restricted to Java developers working in or around London (or those hoping to train in Java, or relocate to London). Membership will not be granted to those involved in the recruitment industry.

Is there a fee to Join, is there a fee for the events?

It’s completely free to join and 99% of our events are completely free. The only event which is charged for is the Unconference, the charge is minimal and it is there to cover refreshments on the day.

Do you have to go to every presentation?

Absolutely not – it’s completely up to you which events you attend and which you don’t. Every event attracts a different crowd.

Where are the events held?

Europe's Premier technical training company, Skills Matter (Barbican) sponsor most of our events by providing the venue.

Can I read some member feedback?

We have been collecting feedback for the last few years from our members you can read it here: http://www.meetup.com/Londonjavacommunity/about/comments/?op=all
