Multi-Account Topologies in AWS Data Engineering

1. Introduction

Multi-account topologies in AWS enable organizations to manage resources across different accounts efficiently. This architecture enhances security, compliance, and resource isolation.

2. Why Use Multi-Account Topologies?

• Enhanced Security: Isolate sensitive workloads.
• Cost Management: Monitor and optimize costs per account.
• Resource Isolation: Manage resources without interference.
• Compliance: Meet regulatory requirements more easily.

3. Key Concepts

Understanding the following concepts is crucial for implementing multi-account topologies:

• AWS Organizations: A service to manage multiple AWS accounts.
• Service Control Policies (SCPs): Manage permissions across accounts.
• Account Structure: Organize accounts by purpose (e.g., production, development).
• Cross-Account Access: Share resources securely between accounts.

4. Best Practices

• Use AWS Organizations to streamline account management.
• Implement SCPs to enforce policies at the organizational level.
• Regularly audit accounts for security compliance.
• Utilize consolidated billing for cost savings.
