AWS Landing Zone - AWS Services

Introduction:

In my previous post, AWS Landing Zone - Overview, I introduced the core concepts behind AWS Landing Zone and explained its purpose in setting up a secure, multi-account AWS environment. In this follow-up, we'll dive deeper into the key AWS services needed to implement a successful AWS Landing Zone. These services will help you automate governance, security, and networking while providing scalability and compliance in your multi-account setup. Whether you are just starting with AWS or looking to enhance your existing infrastructure, understanding these services will lay the foundation for a robust AWS environment.

AWS Services for Building a Landing Zone

Here’s a breakdown of the essential AWS services for setting up and managing an AWS Landing Zone:

Multi-Account Management

  • AWS Organizations: Used for centralized account creation, management, and applying governance through Service Control Policies (SCPs).
  • AWS Control Tower: Provides an easier alternative to AWS Landing Zone, helping you set up and govern a secure multi-account AWS environment. Control Tower automates the creation of accounts and applies pre-configured guardrails.

Identity and Access Management

  • AWS IAM: Configure roles, permissions, and policies across multiple accounts to manage access.
  • AWS SSO: Enables centralized user and role management with Single Sign-On capabilities, simplifying access control across accounts.
  • AWS Directory Service: Integrates with your on-premises Active Directory or creates a managed directory in AWS for user management.

Networking

  • Amazon VPC: Create isolated virtual networks for your workloads to enhance security and control traffic.
  • AWS Transit Gateway: A centralized hub for connecting multiple VPCs across AWS accounts and on-premises networks.
  • AWS Direct Connect: Establish private, high-speed connections between your on-premises data centers and AWS.
  • AWS PrivateLink: Enables secure connectivity between VPCs without exposing traffic to the public internet.

Security

  • AWS CloudTrail: Logs all AWS account activity to help with auditing and governance.
  • AWS Config: Tracks configuration changes and ensures compliance with defined policies.
  • AWS GuardDuty: Continuously monitors for threats and suspicious activity.
  • AWS Security Hub: Centralized security management and compliance monitoring.
  • AWS KMS (Key Management Service): Encrypt data to secure sensitive information.
  • Amazon Inspector: Performs automated security assessments and vulnerability scanning.

Logging and Monitoring

  • Amazon CloudWatch: Provides comprehensive monitoring for AWS resources and applications, helping you track performance and health.
  • AWS CloudTrail: Collects logs for auditing API calls and user activity across AWS services.
  • Amazon S3: Centralized storage for logs and other data.
  • AWS Lambda: Automate log processing, analysis, or respond to security events in real-time.

Governance and Compliance

  • AWS Service Catalog: Helps maintain consistency by allowing you to create and manage pre-approved resource templates.
  • AWS Trusted Advisor: Suggests best practices for cost optimization, performance, and security.
  • AWS Control Tower: Automates governance with built-in guardrails for compliance across accounts.

Automation and Deployment

  • AWS CloudFormation: Automates the provisioning of AWS resources based on predefined templates.
  • AWS CodePipeline: Provides continuous integration and delivery (CI/CD) workflows for deployment automation.
  • AWS Step Functions: Orchestrates workflows for various processes like account setup, compliance checks, and security tasks.

Data and Storage

  • Amazon S3: A highly durable and scalable object storage service for storing logs, data backups, and other artifacts.
  • Amazon RDS: Managed relational databases for workloads that require persistent, structured storage.
  • Amazon DynamoDB: A serverless key-value store for fast and flexible application data.

Conclusion

In conclusion, AWS Landing Zone offers a comprehensive approach to managing multi-account environments, and leveraging the key AWS services outlined in this post is essential to building a secure, scalable, and compliant AWS setup. By combining services like AWS Organizations, Control Tower, IAM and CloudTrail, you can automate much of the setup and governance while ensuring a high level of security. If you haven’t already, I recommend reading my previous post on AWS Landing Zone - Overview for a better understanding of the foundational concepts. With the services covered here, you’ll be well on your way to setting up an optimized, secure, and efficient AWS Landing Zone tailored to your organization’s needs.
