Design Microservices Architecture with Patterns and Principles - What Is Load Balancer? Use Load Balancer to Split the L

The video tutorial explains the concept and importance of load balancers in system design, particularly in interviews. It covers how load balancers distribute traffic across servers using algorithms like consistent hashing and round-robin. The tutorial highlights the features of load balancers, such as fault tolerance and scalability, and discusses popular software like Nginx. Consistent hashing is explained in detail, emphasizing its role in handling horizontal scaling and server failures in distributed systems.

What is the primary function of a load balancer in a network?

• To store data securely

• To distribute incoming traffic across multiple servers

• To encrypt data for security

• To monitor server performance

Which of the following is a key feature of load balancers?

• Data encryption

• Fault tolerance

• Data compression

• User authentication

How does a load balancer handle increased traffic?

• By compressing data

• By adding more servers to the network

• By reducing server response time

• By limiting user access

What problem does consistent hashing solve in distributed systems?

• Horizontal scaling

• Data encryption

• User authentication

• Vertical scaling

Why is consistent hashing preferred in distributed microservices?

• It enhances user authentication

• It reduces server costs

• It simplifies data encryption

• It minimizes the need to rearrange data when scaling
