Sammanfattning
Previous research has looked into how to dynamically scale containerized applications with consideration to clients Quality of Experience (QoE), but there is a lack of knowledge on how relay server’s, used for multiplayer games, scale. Through investigating the largest cloud platform providers, three key metrics were identified: Network traffic, memory allocation and CPU utilization. These metrics were investigated depending on several parameters: the clients perceived frequency of messages, the number of clients connected to a server, and the number of clients playing the same game. To do this, a client-simulator program was expanded to work with a pre-existing server developed by Opera Software. The server and client-simulators were used in different environments, both bare-metal machines and containers from Amazon Web Services. Upon analyzation it was found that network traffic and memory allocation scales linearly, while the CPU utilization can only be interpolated withing a range used to train a third degree regression model. The error of all models were fairly low at a maximum of 2,658%.
