This thesis aims to explore the possibilities of communicating with swarms of micro virtual machines in a cloud environment. As the worlds data centers grow larger, so does the focus on energy consumption. This thesis presents a prototype of an architecture which allows for virtual serial communication. Through full feature and synthetic testing it was shown how this prototype could potentially be a communication channel for managing swarms of large virtual machines over a virtual serial interface. The experiments were conducted in a real-life production environment, showing stable results when communicating with potentially thousands of virtual machines. Further improvements of the tools has been investigated with the aim to increase the performance even more.
