Development and deployment of high-availability and automation information systems with a focus on telecommunications

The aim of this bachelor thesis is to analyze the specifics of the development, architecture, and deployment of high-availability (HA) and automation information systems in the telecommunications environment and to propose an appropriate architectural and deployment model using modern cloud-native technologies. Validation of the design is part of the aim. The thesis combines a literature review with expert consultations with the company DataLite, spol. s r. o., which has long-term experience with automation platforms for telecom operators. Based on the research question “Which architectural and deployment approaches are most suitable for the development and operation of high-availability automation information systems in the context of modern cloud-native technologies?”, three hypotheses are formulated. They relate to the suitability of microservices architecture, automated CI/CD pipeline for deploying Docker containers into Kubernetes, and the use of Prometheus and Grafana for monitoring. The theoretical part describes the specifics of the telecom environment, the concept of high availability, and the principles of modern cloud-native systems. The practical part proposes a reference architecture of an automation system, a deployment model, and a concept for monitoring, logging, and alerting for a model operator called Alfa. The outcome of the thesis is a qualitative assessment of the proposed architecture with respect to availability, scalability, security, regulatory compliance (NIS2), and operational efficiency. The conclusion discusses the benefits and limitations of the proposed solution and outlines options for further development.
