1.3 Methodology of the Study

This thesis brings together different resources on concurrency, web architectures and scalable network infrastructures. The primary sources are research publications and technical analyses. Additionally, documentations of design patterns, systems, programming languages and frameworks are considered.

As the main contribution of this thesis, we provide a comprehensive survey on the myriads of different concepts and techniques of concurrency inside web architectures. We compare and evaluate approaches based on their characteristic features and impacts, and provide guidelines for choosing the right approach for a given problem.
