Event-driven Architectures
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.
Sensor Fusion
Geschrieben von Konstantin Rosenberg Einleitung Stell dir vor du fährst in deinem autonom Fahrenden Auto die Straße entlang. Plötzlich erscheint, hinter einem parkenden Auto, ein Fußgänger und tritt direkt vor dir auf die Fahrbahn. Du erschrickst, doch das Auto kommt elegant vor dem unachtsamen Spaziergänger zu stehen. Während du dir gerade nicht einmal sicher bist…
WebSocket-Protokoll: Ein detaillierter technischer Einblick
Das HTTP-Protokoll existiert seit Beginn des Internets und hat sich bis heute in Bezug auf Performance immer weiter entwickelt. Die vielen TCP-Verbindungs-Aufbau-Prozeduren wurden durch das Multiplexing auf ein paar Wenige reduziert, welche jeweils mehrere verschiedene Daten übertragen [7]. Auch der Header selbst wurde auf Performance getrimmt. So wurde aus dem textuellen Format ein binär-Kodiertes. Zudem…
Open Source Batch and Stream Processing: Realtime Analysis of Big Data
Abstract Since the beginning of Big Data, batch processing was the most popular choice for processing large amounts of generated data. These existing processing technologies are not suitable to process the large amount of data we face today. Research works developed a variety of technologies that focus on stream processing. Stream processing technologies bring significant…
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 system. It shows how we set up the scaling infrastructure with Kubernetes and what…
IPFS: the InterPlanetary File System demystified
In this article we will explore IPFS, the InterPlanetary File System. IPFS is a system for storing and accessing files, websites and other kinds of data — just as the Web we enjoy using every day — but unlike the Web, IPFS is peer-to-peer based and automatically distributes its content across the network.
Supply chain on Ethereum Network
600 million people – almost every tenth in the world – fall ill every year with contaminated food, 420,000 of them die (cf. World Health Organization 2019). The main reason for this are supply chains that can not be properly traced back to the source of the contamination (cf. Yiannas 2018). Experts say that the…
