# Getting Started With AWS
## Create an AWS Account
AWS (Amazon Cloud) account creation Prerequisites:
* Credit card
* Landline or mobile phone
* Navigate to the [AWS official website](https://aws.amazon.com/) and click the “Sign Up” button.
* Fill in all registration information including your personal information and credit card details.
* Next, the system will call to confirm your phone number. Enter the 4-digit number (ending with #) displayed on the computer screen.
* If the account was successfully created, your card will be charged for $1 as part of the verification process (this will be refunded later).
## Create a Suitable EC2 Virtual Machine
EC2 virtual machine set up
**1. Create an AWS EC2 instance**
Log in to the [EC2 console](https://console.aws.amazon.com/ec2/):
Select the location of the machine in the upper right corner:
Find “Instances” in the menu on the left side of the page
Then click on the “Launch Instance” button:
Choose an Amazon system image: Ubuntu 22.04 is recommended
Select the instance type. We recommend the m4.large configuration.
Click the “Next: Configure Instance Details” button and input the following default configuration:
Click the “Next: Add Storage” button
The recommended setting is 80GB
Click the “Next: Add Tags” button to add tags for easy recall:
Click the “Next: Configure Security Group” button
Add firewall rule and then click the “Review and Launch” button to verify the instance:
Click the “Launch” button to launch the instance
Create a key, download the key pair and keep it in a safe place. You will use this key when logging in with SSH.
That completes the EC2 instance creation.
## SSH login to AWS EC2
To use the SSH login method under Linux, set the key file permissions with the following command (make sure to replace `your_keyfile.pem` with whatever you named your key file):
```
chmod 400 your_keyfile.pem
```
SSH login command (make sure to replace `your_EC2_ip_address` with your EC2 instance's IPv4 Public IP address:
```
ssh -i your_keyfile.pem ubuntu@your_EC2_ip_address
```
Windows users should use PuTTY to SSH in, see Amazon's [instructions](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html).
Now you are finished. If you would like set up a validator node, please follow the instructions here.
## How to Delete an EC2 instance
First terminate the instance:
Confirm termination:
After termination, check that the volume has been deleted to avoid any costs. In addition, the instance will remain in the list for a while after termination, and will generally disappear within half an hour.
