Amazon EC2 is a web service that provides secure and resizable compute capacity in the cloud. It allows users to launch virtual machines called instances. The key steps are to sign up for AWS, launch an EC2 instance by choosing an AMI, instance type, and security group, configure storage and tags, connect to the instance, and terminate it when finished. EC2 offers benefits like elastic web-scale computing, complete control, flexibility, reliability, security, and low cost.

2. What is Amazon EC2?
Amazon Elastic Compute Cloud (Amazon EC2) is a web
service that provides secure, resizable compute capacity in
the cloud. It is designed to make web-scale cloud computing
easier for developers.

5. 1. Sign Up for AWS
https://aws.amazon.com/
Once you are signed in, you’ll be redirected to AWS Management Console.

6. 2. Launch an Amazon EC2 Instance
a. Enter the Amazon EC2 Console
Type EC2 in the search bar and select Amazon EC2 to open the service console.

7. 2 b. Launch an Instance

8. 3. Configure your Instance
You are now in the EC2 Launch Instance Wizard, which will help you configure and
launch your instance.
In this screen, you are shown options to choose an Amazon Machine Image (AMI).
AMIs are preconfigured server templates you can use to launch an instance. Each
AMI includes an operating system, and can also include applications and application
servers.
Select an instance of your need.

10. b. You will now choose an instance type. Instance types comprise of varying combinations of CPU,
memory, storage, and networking capacity so you can choose the appropriate mix for your applications.
Select an instance type and click Next:Configure Instance Details at the bottom right of the page.

11. Configure your instance details and click Next: Add Storage at the bottom right corner of the page.

12. Add Storage and click Next: Add Tags

13. Add Tags: A tag is a label that you assign to an AWS resource. Each tag consists of a key and an optional
value, both of which you define.
Click Next: Configure Security Group.

14. Configure Security Group
Click Review and Launch

15. Review the settings and click Launch

16. Key Pair
On clicking Launch, you’ll see a prompt to select or create a key pair.
A key pair is used to securely access your Linux instance using SSH. AWS stores the public part of the key pair which is just like a house lock.
You download and use the private part of the key pair which is just like a house key.
Select Create a new key pair and give it a name of your choice. Next click the Download Key Pair button.
After you download the key, you will want to store your key in a secure location. If you lose your key, you won't be able to access your
instance. If someone else gets access to your key, they will be able to access your instance.
After you have stored your key pair, click Launch Instance to start your Linux instance.

17. In the next screen you’ll see the launch status of your instance. Scroll down and
click View Instances.

18. You’ll see something like this....

19. 4. Connect to your instance

21. 5. Terminate your instance
You can easily terminate the instance from the EC2 console. In fact, it is a best practice to terminate instances you are no longer using so you
don’t keep getting charged for them.
a. Back on the EC2 Console, select the box next to the instance you created. Then click the Actions button, navigate to Instance State, and
click Terminate.

22. b. You will be asked to confirm your termination - select Yes, Terminate.
Note: This process can take several seconds to complete. Once your instance has been terminated, the Instance State will change to
terminated on your EC2 Console.

23. A terminated instance

24. Congratulations
You have learned how to use Amazon EC2 to launch,
configure, connect, and terminate an instance in the cloud.

25. Thank you.
