Why inter-service communication defines architecture in Microservices - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to select the communication style used between microservices.

Microservices

communication_style = "[1]"

Drag options to blanks, or click blank then click option'

Amonolithic

Bdatabase

Csynchronous

Dsingle-threaded

Attempts:

💡 Hint

Common Mistakes

Choosing 'database' as communication style, which is a storage method, not communication.

The communication style between microservices is typically synchronous or asynchronous, but synchronous is a common starting point.

2fill in blank

medium

Complete the code to define the message format used in inter-service communication.

Microservices

message_format = "[1]"

Drag options to blanks, or click blank then click option'

AXML

Bbinary

Cplaintext

DJSON

Attempts:

💡 Hint

Common Mistakes

Choosing XML, which is heavier and less common in modern microservices.

JSON is widely used for message formats in microservices because it is lightweight and easy to read.

3fill in blank

hard

Fix the error in the code that sets the communication protocol for microservices.

Microservices

protocol = "[1]"

Drag options to blanks, or click blank then click option'

AFTP

BHTTP

CSMTP

DSSH

💡 Hint

Common Mistakes

Choosing FTP or SMTP, which are for file transfer and email, not service communication.

HTTP is the standard protocol for communication between microservices, especially in REST APIs.

4fill in blank

hard

Fill both blanks to complete the code that defines the communication pattern and its benefit.

Microservices

communication_pattern = "[1]"
benefit = "[2]"

Drag options to blanks, or click blank then click option'

Aevent-driven

Breduces tight coupling

Cshared database

Dincreases latency

Attempts:

💡 Hint

Common Mistakes

Choosing 'shared database' which increases coupling.

An event-driven communication pattern reduces tight coupling between services, improving scalability and flexibility.

5fill in blank

hard

Fill all three blanks to complete the code that sets the communication method, protocol, and message format.

Microservices

communication_method = "[1]"
protocol = "[2]"
message_format = "[3]"

Drag options to blanks, or click blank then click option'

Aasynchronous

BHTTP

CJSON

DTCP

Attempts:

💡 Hint

Common Mistakes

Choosing TCP as protocol, which is lower level than HTTP.

Microservices often use asynchronous communication over HTTP with JSON message format for scalability and readability.
