This talk provides an architecture overview of data-centric microservices illustrated with an example application. The following Microservices concepts are illustrated - domain driven design, event-driven services, Saga transactions, Application tracing and Health monitoring with different microservices using a variety of data types supported in the database - business data, documents, spatial, graph, and events. A running example of a mobile food delivery application (called GrubDash) is used, with a hands-on-lab that is available for attendees to work through on the Oracle Cloud after these sessions. The rest of the talks will build upon this Microservices architecture framework.
