The cloud has fundamentally changed how we design applications and introduced whole new categories of software-development disasters. With a focus on Java, this talk will introduce some of the new tools, patterns, and best practices for modern distributed application development. It also gives a tour of some of the most painful anti-patterns Holly has seen as a cloud consultant.

Target Audience: Architects, Developers, Strategic Decision Makers
Prerequisites: Basic experience of cloud computing,…

You've heard about this new feature in C++20, Coroutines, but it's the first time you have encountered this term? Then this talk is what you're looking for. We start from the beginning with just "normal" functions. Next, we introduce Coroutines. Using them, we explore the various customization points C++ offers. Another distinction we make is cooperative and preemptive multitasking, opening the door for another beauty of Coroutines, why we don't need locks.
By the end of this talk, you've…

As developers, our job is to deliver working software. With the shift to CI/CD and the move to the cloud, the need to have the right feedback at the right time only increases. There are many ways that testing can help us with that. Not only can testing help us verify our solution and prevent us from breaking things, it can also help us design our software, find flaws in our architecture and come up with better solutions. In this talk I will highlight some of the many ways that testing can help…

In this session I’ll examine some of the things that can go wrong when organisations jump headfirst into micro-service architectures without understanding the potential pitfalls.

I'll explain contract testing from the ground up. You'll learn how it can decouple micro-service dependencies during development, allowing your teams to work effectively. And I'll describe sophisticated, free, open-source tooling that helps integrate contract testing into your software lifecycle, giving you the…

Java applications are widely used and often several years old. You can use these applications in the cloud via lift-and-shift (helps nothing) or you can rewrite the application in cloud-native style and use the advantages of the cloud.

An alternative for existing applications is missing here. It must be possible to go to the cloud and use advantages such as serverless and scale-to-zero WITHOUT having to rewrite the entire application.
I will show what is already working well today and where the…
