  • Derek Harmon thinks this is interesting:

communication between the microservice and the sidecar

From

Cover of Microservices for the Enterprise: Designing, Developing, and Deploying

Note

The authors state this communication "is over the network, but doesn't go over the network." They cannot have it both ways.

Presumably, the sidecar is out-of-process but co-located on the same host. What are the implications of this for containerization? Is the sidecar implemented using the technology stack of the upstream domain for which it is translating, or not?
