Ephemeral data handling, whereby processed data do not persist, is an emerging requirement of connected IT systems, due to storage constraints (IoT) or regulatory demands (eHealth, GDPR). We present ongoing work on TQuery, a query language for ephemeral data handling in microservices.

The adoption of edge and fog systems, along with the introduction of privacy-preserving regulations, compel the usage of tools for expressing complex data queries in an ephemeral way. That is, queried data should not persist. Database engines partially address this need, as they provide domain-specific languages for querying data....

The microservice architecture is a style inspired by service-oriented computing that has recently started gaining popularity and that promises to change the way in which software is perceived, conceived and designed. In this paper, we describe the main features of microservices and highlight how these features improve scalability.

Microservices is an architectural style inspired by service-oriented computing that has recently started gaining popularity. Before presenting the current state-of-the-art in the field, this chapter reviews the history of software architecture, the reasons that led to the diffusion of objects and services first, and microservices later....
