Why load balancing matters in Azure - Quick Recap

Recall & Review

beginner

What is load balancing in cloud infrastructure?

Load balancing is the process of distributing incoming network traffic across multiple servers to ensure no single server becomes overwhelmed, improving reliability and performance.

beginner

Why does load balancing improve application availability?

Because it spreads traffic across servers, if one server fails, others can take over, keeping the application running without interruption.

beginner

How does load balancing affect user experience?

It helps keep response times fast and consistent by preventing any one server from getting too busy, so users don’t face delays or errors.

beginner

What is a real-life example of load balancing?

Think of a busy restaurant with multiple waiters. The host directs new guests evenly to each waiter so no one waiter is overwhelmed, ensuring everyone gets timely service.

beginner

Name one Azure service that provides load balancing.

Azure Load Balancer is a service that distributes incoming traffic to multiple virtual machines to ensure high availability and reliability.

What is the main purpose of load balancing?

A To store data securely

B To distribute traffic evenly across servers

C To create virtual machines

D To monitor network security

Load balancing distributes incoming traffic evenly to prevent any server from being overloaded.

How does load balancing improve application reliability?

A By redirecting traffic if a server fails

B By backing up data regularly

C By encrypting user data

D By increasing server storage

If one server fails, load balancing redirects traffic to healthy servers, keeping the application available.

Which Azure service is used for load balancing?

A Azure Functions

B Azure Blob Storage

C Azure Load Balancer

D Azure Cosmos DB

Azure Load Balancer distributes network traffic across multiple servers.

What happens if there is no load balancing and one server gets too much traffic?

A The server may slow down or crash

B The server will automatically create more servers

C The traffic will be ignored

D The server will encrypt the traffic

Without load balancing, a busy server can become overwhelmed, causing slowdowns or crashes.

Load balancing helps improve user experience by:

A Reducing the size of data files

B Increasing the number of users allowed

C Changing the user interface design

D Making response times faster and more consistent

By spreading traffic, load balancing keeps response times quick and steady for users.

Explain in your own words why load balancing is important in cloud applications.

Think about what happens when many users visit a website at the same time.

Describe a simple real-life example that helps you understand how load balancing works.

Consider how tasks or customers are shared among helpers or workers.
