Design of Fault-Tolerant and Low-Latency Service Interaction in Enterprise

Many companies and enterprises use microservice architecture during building their own IT system. In fact, this approach allows to divide a large system into independent and loosely coupled modules. However, there is an obvious disadvantage of need to transfer data from one service to another, which increases the costs of export, transport, reading and processing. The present master thesis will be focused on various approaches of building data transfer with their advantages and disadvantages, when the system has the requirements of fault-tolerant and low-latency data delivery. The object of study is microservice architecture in software, the subject of the research is interaction of components, data exchange. The goal of term paper is to study the existing approaches to the interaction of services and implement a solution that will comply with SLA. In order to achieve that goal, 2 objectives were set: 1. To study the existing practices of component interaction in microservice architecture. In addition to studying the data delivery pipeline, the goal to study security and tools for monitoring coverage. 2. To implement the most relevant solution as part of the project on permanent place of work. The solution should be based on existing architectural constraints. In the process, two research methods are used: comparative analysis and modeling. In this way, the definition of done are analysis of existing solutions, implementing and launch a project at production with SLA compliance. The thesis contains 62 pages, 3 chapters, 21 figures, 2 tables, 14 formulas, 44 bibliography items, 4 appendices.
