Performance analysis of Web Services : Comparison between RESTful & GraphQL web services

Abstract: In today's interconnected world, we as users constantly demand more information to be accessible from the web. Not only should the data be accessible but a crucial factor is that load times should be fast. With the internet expanding to more devices of different types such as smartphones, tablets, IoT devices and more, this factor becomes even more important. The most commonly used service today for serving data between clients and a server is REST, which has been the leading service used for this purpose for many years. This research paper focuses on identifying the differences in performance between RESTful services and Facebook's GraphQL. These two technologies are the two most commonly used and talked about solutions when it comes to serving data between clients and servers as of today, with more developers moving towards the newer GraphQL.
