The microservice architecture have encouraged the splitting of large scale applications into smaller services that are good at performing single task to take advantage of the following benefits: Independent service deploymentsFaster release cyclesEasier maintenanceGranular scalability However, this microservices don't come without its own set of problems. Splitting of services meant that APIs needed to be grouped into smaller sets (Bounded contexts) and this offloaded problems to client-side and API applications. Client-side Issues Leaking domain knowledge Since client-side applications now have to deal with multiple APIs, this means that domain knowledge is now scattered across consumers thus, making them harder to maintain.
