The Landing Zone Accelerator (LZA) on AWS solution is now the recommended solution for organizations seeking to automate the deployment of a new high compliance AWS Environment.
The LZA v1.3 release (03/2023) focused on delivering AWS Secure Environment Accelerator (ASEA) feature parity and delivered both CCCS Cloud Medium and Trusted Secure Enclave Sensitive Edition sample configuration files. These samples deliver similar outcomes to the ASEA sample configuration file.
The LZA team is currently developing a semi-automated upgrade from ASEA to LZA. Upgrades from ASEA to LZA must occur before Q2 2024. Please monitor this site for a future LZA release that will support the ASEA to LZA semi-automated upgrade capability here.
Please reach out to your AWS Account Team with any questions.
The AWS Accelerator is a tool designed to help deploy and operate secure multi-account, multi-region AWS environments on an ongoing basis. The power of the solution is the configuration file that drives the architecture deployed by the tool. This enables extensive flexibility and for the completely automated deployment of a customized architecture within AWS without changing a single line of code.
While flexible, the AWS Accelerator is delivered with a sample configuration file which deploys an opinionated and prescriptive architecture designed to help meet the security and operational requirements of many governments around the world. Tuning the parameters within the configuration file allows for the deployment of customized architectures and enables the solution to help meet the multitude of requirements of a broad range of governments and public sector organizations.
The installation of the provided prescriptive architecture is reasonably simple, deploying a customized architecture does require extensive understanding of the AWS platform. The sample deployment specifically helps customers meet NIST 800-53 and/or CCCS Medium Cloud Control Profile (formerly PBMM).
A common misconception is that the AWS Secure Environment Accelerator only deploys security services, not true. The Accelerator is capable of deploying a complete end-to-end hybrid enterprise multi-region cloud environment.
Additionally, while the Accelerator is initially responsible for deploying a prescribed architecture, it more importantly allows for organizations to operate, evolve, and maintain their cloud architecture and security controls over time and as they grow, with minimal effort, often using native AWS tools. While the Accelerator helps with the deployment of technical security controls, it’s important to understand that the Accelerator is only part of your security and compliance effort. We encourage customers to work with their AWS account team, AWS Professional Services or an AWS Partner to determine how to best meet the remainder of your compliance requirements.
The Accelerator is designed to enable customers to upgrade across Accelerator versions while maintaining a customer’s specific configuration and customizations, and without the need for any coding expertise or for professional services. Customers have been able to seamlessly upgrade their AWS multi-account environment from the very first Accelerator beta release to the latest release (across more than 50 releases), gaining the benefits of bug fixes and enhancements while having the option to enable new features, without any loss of existing customization or functionality.
Specifically the accelerator deploys and manages the following functionality, both at initial accelerator deployment and as new accounts are created, added, or onboarded in a completely automated but customizable manner:
- Core Accounts - as many or as few as your organization requires, using the naming you desire. These accounts are used to centralize core capabilities across the organization and provide
Control Panellike capabilities across the environment. Common core accounts include:- Shared Network

The ALZ was an AWS Solution designed to deploy a multi-account AWS architecture for customers based on best practices and lessons learned from some of AWS' largest customers. The AWS Accelerator draws on design patterns from the Landing Zone, and re-uses several concepts and nomenclature, but it is not directly derived from it, nor does it leverage any code from the ALZ. The Accelerator is a standalone solution with no dependence on ALZ.
The AWS Secure Environment Accelerator now leverages AWS Control Tower!
With the release of v1.5.0, the AWS Accelerator adds the capability to be deployed on top of AWS Control Tower. Customers get the benefits of the fully managed capabilities of AWS Control Tower combined with the power and flexibility of the Accelerators Networking and Security orchestration.
This summarizes the installation process, the full installation document can be found in the documentation section below.
- Create a config.json (or config.yaml) file to represent your organizations requirements (several samples provided)
- Create a Secrets Manager Secret which contains a GitHub token that provides access to the Accelerator code repository
- Create a unique S3 input bucket in the management account of the region you wish to deploy the solution and place your config.json and any additional custom config files in the bucket
- Download and execute the latest release installer CloudFormation template in your management accounts preferred 'primary' / 'home' region
- Wait for:
- CloudFormation to deploy and start the Code Pipeline (~5 mins)
- Code Pipeline to download the Accelerator codebase and install the Accelerator State Machine (~10 mins)
- The Accelerator State Machine to finish execution (~1.25 hrs Standalone version, ~2.25 hrs Control Tower Version)
- Perform required one-time post installation activities (configure AWS SSO, set firewall passwords, etc.)
- On an ongoing basis:
- Use AWS Organizations to create new AWS accounts, which will automatically be guardrailed by the Accelerator
- Update the config file in CodeCommit and run the Accelerator State Machine to:
- deploy, configure and guardrail multiple accounts at the same time (~25 min Standalone, ~50 min/account Control Tower)
- change Accelerator configuration settings (~25 min)
