Service loose coupling: Services maintain a relationship that minimizes dependencies and only requires that they maintain an awareness of each other. Service abstraction: Beyond descriptions in the service contract, services hide logic from the outside world. Service reusability: Logic is divided into services with the intention of promoting reuse. 5. Service autonomy: Services have control over the logic they encapsulate. 6. Service statelessness: Services minimize resource consumption by deferring the management of state information when necessary 7.
