Question

A. Isolating them completely
B. Minimizing documentation
C. Using incompatible communication protocols
D. Establishing a well-defined API

Answer 1

A critical consideration for ensuring successful communication between two microservices is establishing a well-defined API.

Step-by-step explanation:

A critical consideration for ensuring successful communication between two microservices is establishing a well-defined API. An API, or Application Programming Interface, defines a set of rules and protocols that allow different software systems to communicate with each other. By establishing a well-defined API, the microservices can communicate effectively by understanding the format and structure of the messages exchanged between them.
