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: 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.
This counter field is initially set at some value that is decremented by one each time the packet "hops." When the counter reaches zero the packet is disposed of.
I'm not too experienced with code including external memory, but i believe there was an error with the code mixing that either mixed lines of code up or got rid of code to save files onto your device. Try looking up code for the device, see if that helps at all.
