Master Microservices with Spring Boot and Spring Cloud - Step 15 – Setting Up Dynamic Port in the Response

The video tutorial explains the implementation of a currency calculation service that interacts with a currency exchange service. It covers the creation of multiple instances of the exchange service running on different ports and the modification of the service to include the port number in its response. The tutorial also demonstrates how to use the Spring Boot environment to dynamically obtain the port number and configure the application to run on different ports using VM arguments.

What is the primary role of the currency calculation service?

• To manage user accounts

• To provide user authentication

• To convert currency values using the exchange service

• To store currency values

Why is it important to distinguish between different instances of the currency exchange service?

• To ensure data security

• To balance the load across servers

• To identify which server is responding

• To reduce server costs

What is the purpose of adding a port to the currency exchange service response?

• To enhance security

• To identify the responding server instance

• To reduce server load

• To increase response speed

How can the port be retrieved in a Spring Boot application?

• Through the application.properties file

• Using a hardcoded value

• By querying the database

• Using the environment object

What is a VM argument used for in this context?

• To set the server port externally

• To manage user sessions

• To increase application speed

• To enhance security

How can you run multiple instances of the currency exchange service simultaneously?

• By increasing server memory

• By using multiple user accounts

• By setting different server ports

• By using different databases

What happens when you hit localhost:8001 after setting up multiple instances?

• It redirects to localhost:8000

• It returns the port as 8000

• It returns an error

• It returns the port as 8001
