The bachelor thesis focuses on the analysis and comparison of database systems suitable for distributed services deployed in the Google Cloud Platform environment. The theoretical part describes selected relational, non-relational and NewSQL databases, including their scalability, replication mechanisms and consistency properties. The practical part consists of the implementation of a benchmarking tool in Go and an analytical tool in Python, which are used for workload generation, metric collection and processing of measurement results. The experimental evaluation was performed on Cloud SQL, AlloyDB, Self-managed Cassandra, GCP Bigtable, GCP Firestore and GCP Spanner. The evaluation focuses on write latency, application-level data visibility in a second region, regional differences, runtime stability and operational costs. The results provide both a qualitative and quantitative comparison of the selected database solutions and support the assessment of their suitability for distributed cloud services.
