For reliable, user-controlled and trustworthy file storage in the cloud, free software prototypes like NubiSave have become great tools to investigate and lift the barrier towards acceptable migration paths. For structured data storage and processing, several approaches to database-as-a-service (DBaaS) have been proposed by researchers and developers but a clear recommendation of how to best manage rows or records of data in the cloud from a practicality angle is still absent. Partially, the question about how to do this is due to the different pricing structures and availability guarantees by the providers which are not trivial to compare. Often, running the database system as set of replicated or sharded containers being part of the application appears to be a valid alternative to the binding of existing commercial DBaaS, if done correctly. After all, cloud providers would offer the same technical guarantees for any of their services. An analysis of which configuration works better and is less expensive would thus be needed.
