• Data-Centric Consistency

• Strict Consistency

• Eventual Consistency

• Causal consistency

• Not be called from other services

• Hide the implementation of a service

• Consist of a big enough service

The main benefit of decoupling an application is to:

• Reduce memory usage

• Enable data synchronization across the web application layer.

• Reduce inter-dependencies so failures do not impact other components.

• Have the ability to execute automated bootstrapping actions.

• Create a tightly integrated application

• Re-develop the legacy component

• API

• Interceptor

• RPC

• processes do not know each other explicitly

• processes communicate through network

• processes communicate entirely through tuples

• no need for two communicating processes to be executing at the same time

• coordination takes place in a direct way
