Question

You have two microservices that need to communicate with each other without holding up a thread on either end. One service will receive an ID and return a message once the job is complete.
Which communication framework should be used?
A.) Have a shared database that allows both
applications to read and write to the tables to share the data instead of having to communicate
B.) Use asynchronous messaging to send and receive messages between each microservice
C.) Abandon the microservice architecture so no interaction is needed
D.) Create a third service to handle the interaction between the services
E.) Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available

Answer 1

Answer: E. Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.

Explanation:

Since there are two microservices that need to communicate with each other without holding up a thread on either end, the communication framework should be used is a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.

REST is a software architectural style which is used in defining the set of rules that be used for the creation of web services. The REST architecture allows requesting systems to be able to access and manipulate web resources.
