Many organizations start their AWS journey with a single account. Development, testing, and production teams may run in the same account because, at the start, there are few resources to manage. But as more users come on board and workload grows, that simplicity fades. Over time, access becomes harder to track, security controls can vary across environments, and costs become more difficult to separate.
This is where a cloud landing zone becomes useful. It provides a structured foundation for your AWS environment as it grows. It defines account boundaries and access controls and sets clear rules for networking, security monitoring, and logging.
This blog explains what a cloud landing zone is, how AWS structures one, and how to set one up effectively.
What Is a Cloud Landing Zone?
A cloud landing zone is a preconfigured cloud environment where an organization can deploy workloads within defined rules and security boundaries. Teams establish the basic cloud setup before deploying applications.
It gives teams a common starting point instead of requiring each project to create its own environment.
What Is an AWS Landing Zone?
In AWS (Amazon Web Services), a landing zone commonly uses multiple accounts instead of placing every workload in one account. AWS Organizations centrally manages these accounts, while Organizational Units (OUs) group accounts that require similar policies.
Consider an organization that handles customer data. Its production workloads may need stricter access controls than its internal testing workloads. Keeping them in separate accounts makes those requirements easier to enforce.
Account boundaries should follow workload, security, and compliance requirements rather than the company’s reporting structure.
The key question is: Which workloads need different policies or controls? The answer helps establish account and OU boundaries.
Why Organizations Use a Multi-Account Cloud Architecture
A multi-account cloud architecture separates workloads into different accounts. This helps separate access security and billing between accounts.
For example, separating production and development limits the impact of changes made in one environment.
More accounts do not automatically improve your cloud environment. Each account should serve a specific purpose, such as workload isolation, centralized services, or meeting compliance needs.
Cloud Landing Zone Architecture: How Is It Structured?
A cloud landing zone is typically organized across multiple AWS accounts and Organizational Units (OUs). Each account has a defined purpose, while OUs group accounts that need similar governance policies.
A practical AWS landing zone may include the following account and OU structure. The exact design should reflect workload and governance requirements.
| Account/OU | Primary Role | Example Use |
| Security | Security monitoring and investigations | Manage security tools and review alerts |
| Infrastructure | Shared platform service | Manage networking, DNS, and shared resources |
| Production | Business-critical workloads | Host live applications and services |
| Development | Application development and testing | Build and test new features |
| Sandbox | Experimentation and learning | Evaluate services and test ideas |
In AWS Control Tower, the shared accounts include the management account, Log Archive account, and Audit account. These support centralized management, logging, and security or compliance.
Understanding the AWS Control Tower Landing Zone
AWS Control Tower makes it easier to manage multiple AWS accounts from a central setup. It works with AWS Organizations and can integrate with IAM Identity Center to support centralized account and access management.
AWS customer Liferay, reported a 70% reduction in AWS account provisioning time after using AWS Control Tower. This shows how a standardized account setup can reduce manual work as an AWS environment grows.
Control Tower provides preventive, detective, and proactive controls, while Account Factory helps teams provision new AWS accounts with standardized configurations.
Together, these capabilities support governance across the landing zone, including account structure, security, and access.
How a Cloud Landing Zone Supports a Secure AWS Environment
- Identity and access: Apply least-privilege permissions, MFA, and centralized workforce access. Prefer temporary credentials over long-lived access keys.
- Security monitoring: Use AWS CloudTrail for activity logging and AWS Config for configuration tracking. Amazon GuardDuty and AWS Security Hub can support threat detection and security findings.
- Organization-level controls: Use Service Control Policies to restrict actions that should not be allowed across AWS accounts.
- Centralized logging: Store security and audit logs in a dedicated Log Archive account with restricted access.
AWS Cloud Landing Zone Best Practices
Assign clear ownership: Define who manages the landing zone and approves major changes.
Automate repeatable tasks: Reduce manual work when creating accounts or applying standard configurations.
Keep controls practical: Use controls that address genuine security, compliance, and operational risks.
Apply tags from the start: Use consistent tags to support cost tracking, ownership, and resource management.
Top 6 Cloud Landing Zone Setup Steps
The exact design varies by organization, but the following sequence provides a practical starting point for an AWS landing zone.
1. Start by Defining Your AWS Requirements
Before designing the environment, identify your workloads, users, security requirements, and AWS Regions.
2. Create and Secure the Management Account
Use the management account for organization-wide AWS settings and keep production workloads in separate member accounts.
3. Set Up AWS Control Tower
Configure AWS Control Tower and choose the home Region carefully, because it cannot be changed after the landing zone is set up.
4. Organize Your Accounts Into OUs
Group accounts according to the policies and controls they need.
5. Standardize New Account Creation
Configure Account Factory to provision new AWS accounts with standardized configurations.
6. Test the Setup With a Real Workload
Test the setup with a small workload and fix access, networking, or security issues before expanding.
Cloud Landing Zone Mistakes to Avoid
Avoid unnecessary complexity: Create accounts and controls only when they serve a clear workload, security, or compliance need.
Balance security and usability: Controls should reduce risk without creating unnecessary friction for development teams.
Treat the landing zone as an evolving foundation: Review account structures, controls, and configurations as workloads and business requirements change.
Conclusion
A well-planned cloud landing zone gives organizations a strong foundation for using AWS. The key is to start with clear goals, keep the design practical, and make decisions that support both technical teams and business needs. As your AWS environment grows, a good foundation makes it easier to add new projects without major changes later.

FAQs
Q1. When Should You Use Landing Zone Accelerator on AWS?
Answer: Use Landing Zone Accelerator on AWS when a standard AWS Control Tower setup does not meet your security or compliance needs. Large organizations often use it when they need stronger controls across many AWS accounts and regions.
Q2. Can Existing AWS Accounts Be Added to a Cloud Landing Zone?
Answer: Yes. You can add existing AWS accounts to a cloud landing zone. Some accounts may need changes to access settings, logging, and security controls to meet landing zone requirements.
Q3. How Does a Cloud Landing Zone Simplify New Team Onboarding?
Answer: A cloud landing zone gives new teams access to preconfigured AWS accounts with standard permissions and controls. This helps them deploy workloads faster with fewer setup tasks.
