AWS Cloud Path Week 2 - Set up CLI & Understand AWS Global Infrastructure

In this week’s livestream on AWS Cloud Path journey (📲 Subscribe to this WhatsApp channel to stay updated on what we are working on!), we dove into essential concepts for navigating AWS effectively. Here's a detailed recap to help you catch up and stay on track!

🛠️ Setting up the AWS CLI

The AWS CLI (Command Line Interface) is a powerful tool for managing AWS resources using commands. Here's what we covered:

1. Why use the CLI?

   • Faster and more efficient for repetitive tasks compared to the console.
   • Ideal for automation and scripting.

2. Installing the CLI:

   • Step-by-step guide for Windows, macOS, and Linux.
   • Key commands: which aws and aws --version to verify the installation.

3. Configuration:

   • Setting up access keys using aws configure.
   • Key fields:
     • AWS Access Key ID.
     • AWS Secret Access Key.
     • Default region (e.g., us-east-1).
     • Default output format (e.g., JSON).
   • Tip: Use AWS IAM best practices to create users and attach the appropriate policies (check last week’s session here).

4. Testing your setup:

   • Commands like aws s3 ls to confirm your CLI is working.

🌍 AWS Global Infrastructure

The AWS Global Infrastructure is the backbone of its cloud services. Here's what we learned:

1. Regions & Availability Zones:

   • Region: A distinct geographic area (e.g., eu-central-1, eu-west-1).
   • Availability Zone (AZ): Independent data centers within a region, ensuring high availability and fault tolerance.

2. Edge Locations & Content Delivery:

   • Edge locations are part of AWS's Content Delivery Network (CDN), Amazon CloudFront.
   • They ensure faster content delivery by caching data closer to end users.

3. Key Benefits of the Global Infrastructure:

   • High availability: Spread workloads across multiple AZs for fault tolerance.
   • Low latency: Regions and edge locations optimize speed for global users.
   • Scalability: Dynamically allocate resources as needed.

4. Choosing the Right Region:

   • Factors to consider:
     • Latency: Choose a region closer to your end users.
     • Services: Not all services are available in every region.
     • Compliance: Meet data residency and regulatory requirements.
   • Tip: Use the AWS Regional Services List for guidance.

🚀 Pro Tips & Resources

• Use the AWS Global Infrastructure map to explore regions and AZs.
• For beginners, try setting up a small project (e.g., creating an S3 bucket) using the CLI.
• Check out the AWS IAM Best Practices for secure key management.
