One of the issues we dealt in the past was the unified data storage, data modeling and databases, the whole application -regardless of the many purposes of its features and capabilities, had to deal with. Data storage tended to be expensive and all components and modules were subject to a single entity in the data access and data storage layer.
Conversely, one of the multiple benefits of the cloud are the many options and tools for data modeling, data querying and data storing, that are distributed, managed, and typically cost efficient. This diversity of serverless options and some advanced mechanisms for data modelling and querying specification and management, ranging from Open API, to the multiple API gateways and database as a data platform offerings, are simplifying the way we work with databases today.
