Design and Implementation of a Centralized Azure APIM Platform

Main goal of this diploma thesis is to design and implement automated solution, focused on the shared API Management service within the Microsoft Azure Cloud. The solution is made to simulate a real case involving a shared service provider and customers interested to use this functionality. Preceding the design itself is an analysis of three existing cloud solutions in the API management domain, compared based on defined criteria. The analysis serves as a starting point, indicating the reasons for choosing to build the design on the Microsoft Azure Cloud. A literature review was conducted based on the analysis of cloud solutions to supplement necessary information for the design implementation. The solution design itself encompasses architectural elements of infrastructure, access verification through RBAC, and complete automation. Automation includes deployment of infrastructure from both the provider and customer sides, automatic configuration of RBAC permissions, and a universal automation pipeline that, based on the OpenAPI file, parameter file, and policy definition files, assembles the API interface settings tailored for a specific customer. In conclusion, two test scenarios are proposed and implemented to verify the correctness and functionality of the implemented solution. Overall, these steps represent a systematic approach to optimizing API management in a cloud environment, involving analysis, automation, security measures, and implementation verification through test scenarios.
