EC2:

Amazon Elastic Compute Cloud (EC2) is a cool thing from Amazon Web Services (AWS). It's like renting a computer, but it's in the cloud. They call these rented computers "instances." You can run your apps on these instances, and the best part is you can change how many you have whenever you want. It's like having a magic elastic computer that can grow or shrink based on what you need. EC2 gives you different types of these instances to choose from, so you can pick the one that's just right for you.

Why do we need an EC2 instance?

EC2 is awesome because it's like having a computer that can change size. When you need more power, you just get more instances. And when you're done, you can give them back. This is super handy because you only pay for what you use. No wasted money on big computers when you only need a little one.

Creating an EC2 instance

Step 1: Get into AWS

First, you gotta log in to AWS. If you don't have an account, you need to make one. Once you're in, find the EC2 thing and start making an instance.

Step 2: Give it a Name

Just pick a name for your instance. Whatever you like.

Step 3: Pick a Picture

You need to choose a picture for your instance. It's like picking a wallpaper for your computer. Amazon calls these pictures AMIs. There are lots to choose from, like Amazon's own Linux, Ubuntu, and even Windows.

Step 4: Choose the Size

Decide how big and strong you want your instance to be. This is where you pick how much brain and muscle it has. There are small ones and big ones, fast ones and slow ones. Just find the one that fits your needs and your wallet.

Step 5: Make a Key

Create a key thing so you can unlock your instance. Keep it safe because it's your special key to get in.

Step 6: Set the Rules

Your instance needs protection, like a virtual force field. This is called a security group. You can make a new one or use an old one. It decides what can come in and what can go out.

Step 7: Get Some Space

Instances need space for their stuff. You can add different kinds of storage, like Amazon's Elastic Block Store or some other storage thing.

Step 8: Double-Check and Go

Before you hit the launch button, make sure everything looks good. If you need to change something, go ahead. Once you're set, press launch, and your instance is born.

Step 9: Talk to Your Instance

Now that your instance is alive, you can chat with it. Use SSH or Remote Desktop or some special AWS thing to connect. No need for a public address if you use the AWS Systems Manager Session Manager.

Conclusion

Making an EC2 instance is easy. Just a few clicks, and you have your own cloud computer. Follow these steps, and you're in the cloud club with your own magic elastic computer.
