Create AWS Free account

2. Choose Sign Up.
   Note: If you've signed in to AWS recently, the button might say Sign In to the Console.
3. Enter your account information, and then choose Continue.
   Important: Be sure that you enter your account information correctly, especially your email address. If you enter your email address incorrectly, you won't be able to access your account. If Create a new AWS account isn't visible, first choose Sign in to a different account, and then choose to Create a new AWS account.
