WEI Landing Zone Accelerator - AWS Multi-Account Foundation

WEI Landing Zone Accelerator helps organizations establish a secure, repeatable cloud foundation before they migrate, modernize, or build workloads on AWS. The engagement combines enterprise architecture, cloud governance, security engineering, networking, automation, and operational design to deliver a multi-account AWS environment aligned to your business objectives, risk posture, compliance obligations, and operating model.

A landing zone is more than a collection of AWS accounts. It is the standardized platform that enables teams to provision, govern, monitor, secure, and operate workloads consistently at scale. WEI designs the foundation around your specific requirements for account governance, identity, networking, centralized logging, security operations, policy controls, workload onboarding, and ongoing platform ownership.

WEI implements the landing zone using one of two primary paths, selected during discovery and design:

• AWS Landing Zone Accelerator on AWS (LZA): An AWS solution built on AWS CDK and configuration files, designed to extend AWS Control Tower with additional governance, security, networking, compliance, and account-vending capabilities. WEI deploys or enhances AWS Control Tower as the foundational multi-account service and configures LZA on top of it, managing the environment as code.

• Terraform: For customers with an established Terraform standard, existing modules, repositories, and CI/CD workflows, WEI designs and implements the landing zone using Terraform, preserving your existing DevOps and platform-engineering practices.

WEI configures AWS-native security services including AWS Security Hub, Amazon GuardDuty, AWS Config rules, Service Control Policies (SCPs), and centralized logging via AWS CloudTrail and Amazon CloudWatch. Encryption is managed through AWS KMS with customer-managed keys. These controls support organizations operating under compliance frameworks such as HIPAA, PCI DSS, SOC 2, and FedRAMP, with configurations tailored to your specific regulatory requirements.

Engagements follow a structured methodology:

1. Discovery and Design - Requirements gathering, architecture decisions, implementation-path selection, and scoping
2. Build and Deploy - Account structure provisioning, networking, identity integration, security baseline deployment, and CI/CD pipeline configuration
3. Validate and Handoff - Testing, documentation walkthroughs, operational runbooks, and knowledge transfer

Key Deliverables:

• Architecture decision document and account-structure diagram
• Deployed AWS Control Tower/LZA environment or Terraform-based foundation
• Security baseline with configured guardrails and detective controls
• Operational runbooks and platform evolution roadmap
• IaC repositories with CI/CD pipeline integration

A regulated financial services organization preparing for its first production workload on AWS engaged WEI to design a multi-account foundation with centralized logging, network segmentation, and compliance-aligned security controls - enabling their application teams to begin deploying workloads on a governed platform rather than building ad hoc infrastructure.

To begin, schedule a discovery call with WEI. During this initial conversation, a named WEI engagement lead will assess your current environment, compliance requirements, and platform-engineering preferences to determine the right implementation path and scope for your organization.

The result is a documented, operationally sustainable cloud foundation that gives application and infrastructure teams a safer, faster path to deploy workloads on AWS while preserving your ability to manage and evolve the platform over time.
