Comparison of the influence of monolithic and microservice architectures on agile projects in the e-commerce area

This work deals with the topic of comparison of influence of monolithic and microservice architecture on agile projects in the E-Commerce area. The main objective of this work is to compare advantages and disadvantages of monolithic and microservice architectures used on agile projects in the E-Commerce domain and on project roles in development teams. The theoretical part first introduces prior related scientific works on which this thesis is based on. Then the relationship is explained between E-commerce solutions and software architecture. Afterwards, important terms related to the testing process and infrastructure are described, followed by introduction of project roles on an agile development team. The last chapter of the theoretical part then shows two real cases of migration to microservices, one positive and one negative. The practical part of this work starts defining research goals for interviews that are then conducted with multiple experts on monolithic and microservice architecture projects. Afterwards, interview findings are analyzed and research questions are answered. Based on information from the theoretical part as well as from interview answers, specific architectural problems will be extracted and will serve as areas of practical comparison between monolithic and microservice architectures. The objective of this work will then be answered in the final discussion that will be based on outputs from all the previous parts.
