Master Microservices with Spring Boot and Spring Cloud - Step 22 – Load Balancing with Eureka, Feign, and Spring Cloud L

The video tutorial explains how to implement client-side load balancing in a currency conversion microservice using Spring Cloud and Eureka. It covers setting up multiple instances of a currency exchange service, registering them with Eureka, and using Fain for load balancing. The tutorial highlights the simplicity of the process and the benefits of dynamic load balancing, which automatically adjusts to changes in available service instances.

What is the first step to ensure the currency conversion service works correctly?

• Check if the currency conversion and exchange services are running.

• Configure the load balancer settings.

• Update the service URL.

• Restart the server.

How can you enable load balancing between multiple instances of a service?

• By manually distributing requests to each instance.

• By using Eureka to discover instances and Fain for load balancing.

• By configuring a hardware load balancer.

• By adding a specific URL for each instance.

What happens when a new instance of the currency exchange service starts?

• It requires manual configuration.

• It needs to be added to a load balancer manually.

• It automatically registers with Eureka.

• It does not affect the existing setup.

Which load balancer was used in earlier versions of Spring Cloud?

• Netflix Load Balancer

• Apache Load Balancer

• Spring Cloud Load Balancer

• Ribbon

What is a key benefit of using Eureka and Fain for load balancing?

• It eliminates the need for a naming server.

• It provides client-side load balancing for free.

• It requires no additional configuration.

• It allows for manual load distribution.
