Abstract

Hydra Cluster is an open-source Internet of Things (IoT) project. Hydra compute cluster project. Hydra cluster is a low cost compute cluster built using SBCs, NodeJS and JavaScript. The Hydra microservice library is used to facilitate communication among the hosted computers. It is built using JavaScript, Raspberry Pi. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.
