Your First 24 Hours on AWS: 5 Things Every Beginner Should Do Immediately

Welcome to the world of Amazon Web Services (AWS)! You’ve just created your account, and you might be feeling a mix of excitement and maybe a little overwhelmed. Don’t worry, you’re not alone. This powerful cloud platform offers a vast array of services, but getting started doesn’t have to be daunting.

In your first 24 hours on AWS, focusing on a few key foundational steps will set you up for success and help you navigate the platform with more confidence. Here are five crucial things every beginner should do immediately:

1. Secure Your Root Account with Multi-Factor Authentication (MFA)

This is the most important thing you should do. Your root account has complete access to all AWS services and resources in your account. Protecting it is paramount.

• What is MFA? Multi-Factor Authentication adds an extra layer of security to your account by requiring a second verification code in addition to your password when you log in. This code is usually generated by an app on your phone.
• Why do it immediately? If your root account is compromised, malicious actors could gain full control of your AWS environment, potentially leading to data breaches, unexpected charges, and other serious issues. Enabling MFA significantly reduces this risk.
• How to do it:
  1. Log in to the AWS Management Console using your root account credentials.
  2. Click on your account name in the top right corner and select “Security credentials.”
  3. Expand the “Multi-factor authentication (MFA)” section.
  4. Click “Activate MFA.”
  5. Choose your preferred MFA method (Virtual MFA device is common and free using apps like Google Authenticator or Authy).
  6. Follow the on-screen instructions to scan the QR code and enter the verification codes.

2. Create an IAM User for Daily Use

Never use your root account for day-to-day tasks. Instead, create an Identity and Access Management (IAM) user with specific permissions tailored to what you need to do.

• What is IAM? IAM allows you to manage access to AWS services and resources securely. You can create individual users, groups of users, and define precise permissions for each.
• Why do it immediately? Using a dedicated IAM user with limited permissions follows the principle of least privilege. If this user’s credentials are compromised, the potential damage is limited to the permissions granted to that user, not the entire AWS account.
• How to do it:
  1. While logged in with your root account, navigate to the IAM service (search for “IAM” in the console search bar).
  2. In the left navigation pane, click “Users” and then “Add user.”
  3. Enter a username for your daily use (e.g., yourname-admin).
  4. Select “AWS Management Console access” as the access type and choose “Custom password” (you can require the user to create a new password at the next sign-in).
  5. Click “Next: Permissions.”
  6. For initial setup, you might want to grant this user administrative access for learning purposes. Select “Add user to group” and click “Create group.”
  7. Give the group a name (e.g., Administrators).
  8. In the policy filter, search for “AdministratorAccess” and check the box next to it.
  9. Click “Create group.”
  10. Select the newly created group and click “Next: Tags” (tags are optional but good for organization).
  11. Click “Next: Review” and then “Create user.”
  12. Download the CSV file containing the new user’s credentials and keep it in a secure place.
  13. Sign out of your root account and sign in with the newly created IAM user credentials.

3. Understand AWS Regions and Availability Zones

AWS infrastructure is built around Regions and Availability Zones. Understanding these concepts is crucial for deploying resilient and performant applications.

• What are Regions? A Region is a geographically distinct location with multiple Availability Zones. Examples include us-east-1 (North Virginia), eu-west-1 (Ireland), and ap-southeast-2 (Sydney).
• What are Availability Zones (AZs)? An AZ is one or more discrete data centers within a Region, equipped with redundant power, networking, and connectivity. They are isolated from each other to prevent failures in one AZ from affecting others.
• Why understand them immediately? Choosing the right Region can impact latency, compliance requirements, and cost. Deploying resources across multiple Availability Zones within a Region increases the availability and fault tolerance of your applications.
• How to understand them:
  1. Look at the top right corner of the AWS Management Console. You’ll see the currently selected Region.
  2. Click on the Region name to see a dropdown list of all available AWS Regions.
  3. Start thinking about where your users are located and any data residency requirements you might have. For learning purposes, you can stick with a Region geographically close to you.
  4. As you start deploying resources, pay attention to the Availability Zone options. Aim to distribute your critical resources across multiple AZs for better resilience.

4. Familiarize Yourself with the AWS Management Console

The AWS Management Console is your web-based interface for accessing and managing AWS services. Spending some time exploring it will make it easier to find what you need.

• What is the AWS Management Console? It’s a graphical user interface that provides an organized and intuitive way to interact with the vast array of AWS services.
• Why familiarize yourself immediately? Navigating the console efficiently will save you time and reduce frustration as you start using different AWS services.
• How to do it:
  1. Log in to the console with your IAM user.
  2. Use the search bar at the top to quickly find specific services (e.g., EC2, S3, VPC).
  3. Browse the “Services” menu in the top left corner to see the categories of services offered.
  4. Click on different services to explore their dashboards and features. Don’t worry about understanding everything at once; just get a feel for the layout and organization.
  5. Pay attention to the navigation menus and the information displayed on the overview pages of different services.

5. Set Up Billing Alerts

Cloud costs can sometimes be unpredictable, especially when you’re just starting. Setting up billing alerts will help you monitor your spending and avoid unexpected surprises.

• What are Billing Alerts? These are notifications that you receive when your AWS spending exceeds a certain threshold that you define.
• Why set them up immediately? It’s crucial to keep track of your usage and costs, even in the free tier. Billing alerts provide visibility and allow you to take action if your spending goes higher than expected.
• How to do it:
  1. Navigate to the AWS Billing and Cost Management console (search for “Billing” in the console search bar).
  2. In the left navigation pane, click “Billing preferences.”
  3. Ensure that “Receive billing alerts” is checked. You might need to enable this for the first time.
  4. In the left navigation pane, click “Budgets.”
  5. Click “Create budget.”
  6. Choose a budget type (Cost budget is common).
  7. Define your budget scope (you can choose to track all costs or filter by specific services or tags).
  8. Set your budget amount (you might start with a small amount like $1 to get familiar with the alerts).
  9. Configure your alert thresholds (e.g., send an alert when 50% and 80% of your budgeted amount is reached).
  10. Enter the email addresses you want the alerts to be sent to.
  11. Review and create your budget.
