Flighly maintainable and testable-enables rapid and frequent development and deployment.
Loosely coupled with other services-enables a team to work independently（the majority of time on their servicers）without being impouted by changes to other services and without affecting other services.
（  ）  deployable-enable a team to deploy their services without having to cortdinate with other teams.
Capable of being developed by a small team-essential for high productivity by avoiding the high communication head of large teams.
Services （  ）  using either synchronous protocols such as HTTP/REST or a synchronous protocols such as AMQP. Services can be developed and deployed independently of one another.
