Microservices: Event-Driven systems

24 Oct 2017
14:45 - 15:45

Server side process does react to business events. User actions, timers, other services may trigger states of change, which should be tracked and propagated. A classical implementation is to define a shared database or centralized message queue, locally or in the cloud. When applied to Microservices, this monolithic approach will quickly appear as a limitation.
In this session, we will introduce how Microservices could have their own dedicated persistence layer (i.e. database), and how real-time callbacks could be used to leverage real-time propagation of events, without any centralized message queue. Both ORM and SOA features of the Open Source mORMot framework will illustrate how to write such stand-alone services.
