Next to the powerful Request / Response architecture exists another architecture, the event-driven one. How this architecture works, where the differences to Request / Response systems are and how transactions can be realized will be part of this article.

Kubernetes: from Zero to Hero with Kompose, Minikube, k3sup and Helm — Part 2: Hands-On
This is part two of our series on how we designed and implemented a scalable, highly-available and fault-tolerant microservice-based Image Editor. This part depicts how we went from a basic Docker Compose setup to running our application on our own »bare-metal« Kubernetes cluster.
Kubernetes: from Zero to Hero with Kompose, Minikube, k3sup and Helm — Part 1: Design
This is part one of our series on how we designed and implemented a scalable, highly-available and fault-tolerant microservice-based Image Editor. The series covers the various design choices we made and the difficulties we faced during design and development of our web application. It shows how we set up the scaling infrastructure with Kubernetes and what we learned about designing a distributed system and developing a production-grade Kubernetes cluster running on multiple nodes.
Safety and protection of autonomous vehicles
Autonomous cars are vehicles that can drive to a predetermined destination in real traffic without the intervention of a human driver. To ensure that the car gets from A to B as safely and comfortably as possible, various precautions must be taken. These precautions are explained in the following sections using various questions and security concepts. In addition, further questions are used to answer typical questions in the field of autonomous driving.
Microservices – Legolizing Software Development I
Welcome to our five-part series about microservices and a legolized software development. We’d like to share our lessons learned about architecture, development environment and security considerations with you. We will also explain some issues we stumbled over and what solutions we chose to solve them.
I) In the first part, we present an example microservice structure, with multiple services, a foreign API interface and a reverse proxy that also allows load balancing.
II) Part two will take a closer look on how caching improves the heavy and frequent communication within our setup. [read]
III) Security is a topic that always occurs with microservices. We’ll present our solution for managing both, authentication and authorization at one single point. [read]
IV) An automated development environment will save you. We explain how we set up Jenkins, Docker and Git to work seamlessly together. [read]
V) We finish with a concluding review about the use of microservices in small projects and give an overview about our top stumbling blocks. [read]
Why is parallel programming so hard to express?
by Johannes Frey, Hannes Buchwald, Stephan Soller, Walter Kriha, Benjamin Binder
While trying to understand Hoares famous paper Communicating sequential processes we stumbled upon some interesting problems and concepts referring to parallel programming. In this post we want to share some of the insights we gained by discussing the matter.
SocialCloud – Cloudy this morning … and we’re scaling – Part 5
Cloud computing has so much potential that the possibilities seem to be endless. Without knowing much about it the cloud looks like a magic place for many people.
To give you a more detailed explanation we sum up the design process of our cloud application step by step in the following blog post. Without giving too much away, it can be said that we still put our trousers on one leg at a time ;-).
