Investigation of How Real-Time Event Streams Can be Analysed and Utilised in Distributed Systems at BookBeat AB : Comparing the industry standard and custom implementations

Abstract: Today’s technology companies have large amounts of streamed data flowing through their distributed systems in real time. In order to optimise and understand the effectiveness of their systems, they need to measure and analyse the data without disturbances in business flows. One way of doing this is to make use of Event Stream Processing (ESP). As more detailed insights are constantly requested, faster and more reliable real time processing is needed. The question is, if and how such a solution would affect the pre-existing systems performance and capabilities and how it could be implemented. This thesis develops an ESP system and compares different ways of solving the stated issue by comparing architectures, network protocols and data management methods. The system is then tested, analysed and compared to today’s commercially available software with the purpose of investigating how real-time event streams can be analysed and utilised in distributed systems.
