Technical challenges of creating an IT system in microservices architectural style using cloud services

Abstract

Microservices architecture solves many problems. It gives flexibility in technology choices, scalability, or organising teams that work on given microservices. Nevertheless, like everything in technology, it comes at a cost. It creates many more technical and domain challenges compared to a monolithic system. As a result, the complexity and effort of development grow significantly. The thesis focuses on technical challenges one needs to face when creating a system in a microservices architecture. Based on the completed prototype, the author analyses the challenges like security, data sharing, distributed transactions, how to develop this kind of system locally, and how to prepare a production deployment on the Google Cloud using Kubernetes and Helm.
