A style of communication which spans a multitude of

implementations is communication through common data. This

pattern is used in a situation where one microservice puts data

into a defined location, and another microservice (or

potentially multiple) then make use of this data. It can be as

simple as one microservice dropping a file in a location, and at

some point later on another microservice picking that file up

and doing something with it.

• This integration style is fundamentally asynchronous in nature.
