A cloud-based back-end implementation for the CatFish project

Abstract: At Halmstad University, the CatFish Project aims to measure and report on water quality. The System includes three components, one to measure, one to present, and one to handle data. This thesis explains the development of a cloud-based back-end solution created for the CatFish project. The solution connects IoT devices via the MQTT protocol. The devices are connected to collect and transfer data, later stored in a database, to be presented to a web application via a REST or WebSocket API. The solution is implemented with Amazon Web Services as a cloud service provider and is hosted on their platform.
