The book starts with a brief introduction about Oracle Golden GATE with microservices and how to configure high availability using various methods. Oracle Golden GATE microservices architecture (M A) is a similar architecture based on rest APIs which enable us to configure, monitor, and manage Oracle Golden GATE services using a web-based user interface. Each submodule supports a specific business goal and uses a simple, lightweight, and well-defined interface to communicate with other sets of services. Oracle Golden GATE can interact with custom conflict-resolution routines that customers write to satisfy their business rules.
