Apache Kafka became the de facto standard for microservice architectures. Decoupled applications and Domain-driven Design (DDD) are key benefits. However, that also introduces new challenges like observability of the whole ecosystem. This session explores the problems of distributed Microservices communication and how Kafka, Kubernetes and a Service Mesh like Istio address them. Learn some approaches for combining them to build a reliable and scalable microservice architecture with decoupled and…

Per default, the standard library containers allocate their memory with new and release it with delete. These calls
• do not have deterministic execution times
• can lead to memory fragmentation
In many embedded applications this is not tolerable. Therefore, using standard library containers is not allowed.
With the allocators available since C++17 in the std::pmr namespace (polymorphic memory resources) these disadvantages…

C++20 is more or less out the door. It is probably the biggest change to the language since ever. In this session we will look into some changes that templates received with C++20. The biggest change is the introduction of Concepts.

We don’t stop there. We will also talk about improvements to CTAD and NTTP. Of course, we will also look into how templated lambdas work in C++20.

By the end of the talk you have learned about the newest C++20 template updates and how to apply them.

Throw a line of code into many codebases and it’s sure to hit one or more testing frameworks. There’s no shortage of frameworks for testing, each with their particular spin and set of conventions and, but that glut is not always matched by a clear vision of how to structure and use tests — a framework is a vehicle, but you still need to know how to drive.

Compared to many languages, C++ has had slower widespread adoption of unit testing. This talk takes a deep dive into the practices and…
