Edge computing is revolutionising gaming and streaming services by processing data closer to the user, which greatly reduces latency and enhances bandwidth efficiency. This talk delves into the integration of edge computing with online gaming, focusing on the Gaming as a Service (GaaS) paradigm. Through an analytical model we show that edge-based gaming architectures can outperform traditional cloud gaming solutions in terms of response times. We will discuss insights into the benefits and complexities of edge computing in online gaming, offering a framework for future developments in this dynamic field.
