What is Amazon EC2?

Amazon EC2 (Elastic Compute Cloud) is a service that lets you rent virtual computers to run your applications. It provides flexible computing capacity in the cloud.

beginner

Why is EC2 important for compute tasks?

EC2 allows you to quickly start and stop virtual servers, so you can run your programs without buying physical machines. It scales easily to match your needs.

beginner

How does EC2 help save costs compared to owning servers?

With EC2, you pay only for the time your virtual servers run. You avoid upfront costs and maintenance of physical hardware.

beginner

What does 'elastic' mean in EC2?

'Elastic' means you can easily add or remove computing power as your needs change, like stretching or shrinking a rubber band.

Name a real-life example of using EC2 for compute.

A company can use EC2 to run their website servers. When many people visit, they add more servers. When traffic is low, they reduce servers to save money.

What does EC2 provide?

A Physical servers you must buy

B Virtual computers to run applications

C Storage for files only

D A database service

EC2 provides virtual computers (servers) to run your applications in the cloud.

Why is EC2 called 'elastic'?

A Because it can stretch or shrink computing power easily

B Because it stores elastic files

C Because it is a physical machine

D Because it never changes

'Elastic' means you can quickly add or remove computing resources as needed.

How do you pay for EC2 usage?

A Only for the time your virtual servers run

C Only when you buy physical servers

D No payment needed

You pay for EC2 based on how long your virtual servers run, saving costs compared to owning hardware.

Which of these is NOT a benefit of EC2?

A Quickly start and stop servers

B Pay only for what you use

C Scale computing power up or down

D Automatic hardware repair

EC2 does not automatically repair physical hardware; it provides virtual servers.

What is a common use case for EC2?

A Designing graphics

B Storing photos and videos

C Running website servers that adjust to visitor traffic

D Sending emails

EC2 is often used to run website servers that scale with visitor demand.
