A distributed system consists of several independent computers that communicate with each other over a network. Different distributed system architectures exist in the computer science. The most popular architecture is the Client-Server model. But especially in the parallel computing field, exist among others, Cluster Computing and Cloud Computing. In this course, the fundamentals of Cloud Computing and related technologies are discussed. Practical exercises are an important part of this course because they are essential for thee understanding of these technologies.

Parts of the slide sets are based on the book Cloud Computing: Web-Based Dynamic IT Services, which was published in 2011 by Springer. ISBN: 978-3-642-20916-1

This course has no written exam! Instead, your grade will depend 100% on your work and the results of the semester project. In previous semesters, each group had worked on completely different themes. This semester, all groups will work on one overarching theme.

The semester project in WS2223 has the goal to develop an edge computing solution for the automatic detection of pests (rats, cockroaches, mice). The semester project includes:

• development and setup of sensor nodes with single board computers and camera modules
• deployment of the operating system and the object detection software
• collection of a sufficient number of images for the training and testing of the object detection model (Tensorflow, OpenCV, YOLO)
• development of a backend to manage the sensor nodes by and the collected data. The backend will be deployed as docker container on a Raspberry Pi Kubernetes Cluster with k3s (or a similar solution)
• development of a frontend to present e.g. log information, event messages, and a map of events with proof like images and timestamps. The frontend will be deployed as docker container on a Raspberry Pi Kubernetes Cluster with k3s (or a similar solution) too

The requirements will be collected in class, discussed, and distributed among the individual teams on October 27th. We will try to design and assign the tasks so that the failure of individual team members and teams does not lead to the collapse of the overall project. It is very important that all participants of the module attend class on the 27th of October!
