EC2 is short for Amazon Elastic Compute Cloud

Amazon EC2 is like a special online service that gives you computer power. It's in the cloud, which means it's on the internet, not on your desk.

It's fast to get new computers with EC2. In the past, getting a new computer took a long time because you had to order it, and there were lots of cables to connect. But with EC2, you can have a new virtual computer in just a few minutes.

You can make your computer bigger or smaller whenever you need to. This is great because you only pay for what you use. In the old days, people used to buy big computers and plan for five years in advance. It cost a lot of money. But with EC2, you only pay for the computer power you actually use.

EC2 also helps software developers build strong and reliable programs. It gives them tools to make sure their programs work well, even when things go wrong.

EC2 Pricing Options

There are different ways to pay for Amazon EC2, and they have different benefits.

1. On Demand:

   • This is like paying for electricity. You pay for what you use by the hour or even by the second.

   • For Linux, you pay by the second, and for Windows, you pay by the hour.

   • On Demand is good if you want flexibility without any long-term commitment or upfront payment.

   • It's suitable for apps that have unpredictable workloads or if you're just testing things out.

   • Use it when you're not sure which type of instance you need.

2. Reserved:

   • Reserved means you make a deal with Amazon. You commit for 1 or 3 years.

   • When you reserve, you pay some money upfront, and in return, you get a big discount on the hourly charge.

   • It's great for apps with steady and predictable usage or when you need reserved capacity.

   • You can save more money if you pay all upfront for a 3-year deal.
