Master Microservices with Spring Boot and Spring Cloud - Step 24 – Understand the Need for a Naming Server

The video tutorial explains how Ribbon is used to distribute load between instances of a currency exchange service. It highlights the challenges of manually updating configurations when scaling services dynamically. The tutorial introduces naming servers, specifically Eureka, which facilitate service registration and discovery, allowing services to communicate without hardcoding URLs. This approach simplifies scaling and maintenance by dynamically managing service instances.

What is a limitation of using Ribbon for load distribution?

• It requires manual configuration updates for new instances.

• It cannot handle more than two instances.

• It only works with currency exchange services.

• It automatically updates configurations.

Why is hardcoding service URLs not recommended?

• It simplifies the configuration process.

• It makes the code run faster.

• It can lead to maintenance issues when instances change.

• It allows for dynamic scaling of services.

What is the primary function of a naming server?

• To store user data securely.

• To manage service registration and discovery.

• To calculate currency exchange rates.

• To distribute load among servers.

How does a service discover another service using a naming server?

• By directly connecting to the service's URL.

• By querying the naming server for available instances.

• By manually updating the service list.

• By using a static configuration file.

What happens during service registration?

• A service distributes load among instances.

• A service registers its details with the naming server.

• A service updates its configuration file.

• A service calculates exchange rates.
