This Ph.D. Thesis deals with the design and realization of a streaming platform specifically targeted at large-scale and live, low delay, events. The streaming platform, called SOLEIL (Streaming Of Large scale Events over Internet cLouds), is conceived to be compliant, at its edge nodes, with the WebRTC specification, meaning users can take advantage of its capabilities using a simple browser. Details on both the design and realization processes are provided, and a thorough experimental campaign will prove the validity of the achieved results
