Microservices Architecture vs Service-Oriented Architecture (SOA)

Microservices Architecture is a architectural development technique —a variant of the Service-Oriented Architecture (SOA) structural style— that arranges an application as a collection of loosely coupled services

Service-Oriented Architecture (SOA) has an enterprise scope
Microservices Architecture has an application scope

Service Types

Stateful Service - a service that has a concept of a session or persistence, like a chat service.
Stateless Service - a service that does not have a concept of a session, but rather performs individual self-contained tasks, like a video transcoding service
