Brief

Amazon Web Services (AWS) is a suite of cloud computing services that runs on the same infrastructure that Amazon uses for its e-commerce website. AWS offers a broad set of global computing, storage, database, analytics, application, and deployment services that help organizations move faster, lower IT costs, and scale applications.

However, there are certain limitations based on the resources consumed.

Let's get started with the AWS Account Creation

Step 1 − To create an AWS account, visit this website AWS and sign-up for a new account and enter the required details.

• Select Create an AWS account.

• Enter your account information, and then choose Verify email address. This will send a verification code to your specified email address.

Step 2 − After providing an email address, complete this form. Amazon uses this information for billing, invoicing and identifying the account. After creating the account, sign-up for the services needed.

• Enter a strong password for your root user, confirm it, and then choose Continue.

• Choose Business or Personal.

• Enter your company or personal information.

• Read and accept the AWS Customer Agreement.

• Choose Continue. At this point, you'll receive an email message to confirm that your AWS account is ready to use.

• Enter your country or region code from the list, and then enter a phone number where you can be reached in the next few minutes.

• Enter the code displayed in the CAPTCHA, and then submit.

• When the automated system contacts you, enter the PIN you receive and then submit.

Step 3 - To sign-up for the services, enter the payment information. Amazon executes a minimal amount of transactions against the card on the file to check that it is valid. This charge varies with the region.

• Select one of the available AWS Support plans. For a description of the available Support plans and their benefits, see Compare AWS Support plans.

• Choose Complete signup. A confirmation page appears that indicates that your account is being activated.

Step 4 − The final step is confirmation. Click the link to log in again and it redirects to the AWS management console.

• Check your email and spam folder for an email message that confirms your account was activated. Activation usually takes a few minutes but can sometimes take up to 24 hours.

  After you receive the activation message, you have full access to all AWS services.

• Enter the information about your payment method, and then choose Verify and Continue.

AWS Account Identifiers

AWS assigns two unique IDs to each AWS account.

• An AWS account ID

• A conical user ID

AWS Account ID

It is a 12-digit number like 123456789000 and is used to construct Amazon Resource Names (ARN). This ID helps to distinguish our resources from resources in other AWS accounts.

To know the AWS account number, click Support on the upper right side of the navigation bar in the AWS management console as shown in the following screenshot.

Conical String User ID

It is a long string of alphanumeric characters like 1234abcdef1234. This ID is used in the Amazon S3 bucket policy for cross-account access, i.e. to access resources in another AWS account.

Now the most important step to secure your account in order to prevent accessibility and modification of Instances

Multi-Factor Authentication

Multi-Factor Authentication (MFA) provides additional security by authenticating the users to enter a unique authentication code from an approved authentication device or SMS text message when they access AWS websites or services. If the MFA code is correct, then only the user can access AWS services or else not.

Requirements

To use MFA services, the user has to assign a device (hardware or virtual) to IAM user or AWS root account. Each MFA device assigned to the user must be unique, i.e. the user cannot enter a code from another user's device to authenticate.

How to Enable MFA Device?

Step 1 − Open the following link, IAM

Step 2 − On the web page, choose users from the navigation pane on the right side to view the list of user names.

Step 3 − Scroll down to security credentials and choose MFA. Click activate MFA.

Step 4 − Follow the instructions and the MFA device will get activated with the account.
