Master Microservices with Spring Boot and Spring Cloud - Step 23 – Running Client-Side Load Balancing with Ribbon

The video tutorial covers the use of Ribbon for load balancing in a microservices architecture. It begins with configuring Ribbon and setting up multiple instances of a currency exchange service on different ports. The tutorial demonstrates how to verify the running instances and configure additional ports. It then shows how Ribbon distributes requests between these instances, ensuring load balancing. The session concludes with a summary of the setup and hints at future improvements.

What is the purpose of configuring multiple instances of the currency exchange service on different ports?

• To reduce the cost of running the application

• To make the application easier to debug

• To allow the application to handle more requests simultaneously

• To increase the security of the application

How can you configure a different port for an application instance?

• By updating the user interface settings

• By modifying the database configuration

• By altering the network firewall rules

• By changing the server port in the application properties

What role does Ribbon play in the currency conversion service setup?

• It balances the load between multiple service instances

• It secures the communication between services

• It provides a user interface for the services

• It stores the data for the services

Which ports are used by the currency exchange service instances in this setup?

• 8002 and 8003

• 8000 and 8001

• 8100 and 8200

• 8080 and 8081

What is the observed behavior when requests are sent from the currency converter?

• Requests are rejected if both instances are busy

• Requests are queued until one instance is free

• Requests are distributed between two instances

• Requests are handled by a single instance
