Account Strategy & Identity
OU structure designed for your operations. IAM Identity Center integrated with your existing identity provider. Least-privilege baselines for human and machine identities.
AWS Foundation Services
Build the AWS Foundation You Can Scale On
Every AWS estate eventually needs the foundation it did not start with. Accounts accumulate without structure. Security policy drifts between workloads. Audit and logging become ad hoc. The cost of retrofitting a foundation climbs with every new workload.
We design and deploy AWS landing zones that handle governance, security, networking, and operations as operational requirements - so the next workload lands on a foundation, not on a pile of exceptions.

AWS Foundation Engineering
A Control Tower landing zone built for how you actually operate
We build AWS foundations using Control Tower as the landing zone primitive, extended with the supporting AWS services and Terraform-based automation that most enterprises need.
AWS Grew Up Faster Than Its Foundation
Most AWS estates started small and grew organically without structure. Each addition made sense at the time, but none assumed the others would be there.
IAM policies inconsistent across accounts
Network topology is a mix of peered VPCs and isolated accounts
CloudTrail enabled somewhere, disabled elsewhere
Security Hub findings pile up in accounts nobody owns
New workloads land wherever they can get provisioned fastest
Core Foundation Components
Every foundation decision is made around how you actually operate, not a template.
Networking Foundation
Transit Gateway as inter-account backbone. Centralized egress through inspection VPCs. Route 53 Resolver for DNS across the org. Designed to integrate with on-premises networks.
Security & Compliance Baselines
GuardDuty organization-wide. Security Hub standards. AWS Config conformance packs. Service Control Policies that prevent expensive and dangerous mistakes at the Org level.
How We Deliver
Four-phase approach from assessment through operational handoff.
1
Assessment and Strategy
Two to four weeks. Current-state discovery for existing estates or strategy and design for greenfield. Output is documented target architecture.
2
Landing Zone Deployment
Three to six weeks. Control Tower, Organizations, SCPs, Identity Center, networking foundation, logging and security baselines.
3
Account Migration or Onboarding
Variable duration. Progressive enrollment of existing accounts or onboarding of new workload accounts as needed.
4
Operate
Handoff to your team with documentation, transition to Aegis co-managed services, or hybrid operational model.
What This Engagement Covers
Complete foundation deployment from assessment through operational handoff.
Current-State Assessment
Account inventory, IAM posture, network topology, logging coverage, security baseline, and cost visibility analysis.
Target Architecture
Landing zone design, OU structure, account strategy, identity architecture, network foundation, and security baseline documentation.
Foundation Deployment
Control Tower setup, Organizations configuration, SCPs, IAM Identity Center, Transit Gateway, centralized logging, and Account Factory baselines.
Outcomes
- Standardized account provisioning with automated guardrails
- Centralized logging and audit across all accounts
- Consistent security baselines enforced at the organization level
- Cost governance and allocation that produces answers, not noise
- Network foundation ready for enterprise workloads
Ideal Fit
- Organizations starting their AWS journey that want to build the foundation correctly from the beginning
- Organizations inheriting unstructured AWS estates from mergers or rapid expansion
- Organizations facing compliance requirements their current AWS setup cannot meet
- Organizations planning major AWS expansion where workloads need a proper foundation
Foundation Options
Control Tower, Landing Zone Accelerator, or DIY
The right foundation approach depends on your requirements and operational model.
Recommended
Control Tower
Recommended for most enterprises
AWS-maintained landing zone primitive with guardrails and account factory.
Best Fit
Organizations that want AWS to maintain the landing zone primitive and can work within its account structure model.
Tradeoffs
Less customization than DIY approaches, but faster deployment and AWS-delivered improvements.
IVI Recommendation
Our default recommendation for the large majority of engagements.
Landing Zone Accelerator
For specialized requirements
Customizable foundation for regulated industries and complex compliance needs.
Best Fit
Requirements that exceed Control Tower's guardrails, GovCloud deployments, or specialized compliance frameworks.
Tradeoffs
More complex deployment and maintenance than Control Tower.
IVI Recommendation
We deploy it when Control Tower cannot meet your specific requirements.
DIY with Organizations + Terraform
For maximum control
Custom foundation built entirely with Terraform and AWS Organizations.
Best Fit
Specific operational requirements neither Control Tower nor LZA accommodate, or mature in-house cloud engineering teams.
Tradeoffs
Requires the most ongoing engineering investment and maintenance.
IVI Recommendation
Least common outcome, typically only when other approaches genuinely cannot fit.
Why IVI
AWS foundation engineering as a core practice
AWS Advanced Consulting Partner
Foundation engineering is not a side engagement for us. We deliver it regularly enough that the patterns are battle-tested.
AWS-Native First
We build on Control Tower and Account Factory for the core, and use Terraform for extensions those tools do not cover natively.
Documented, Not Opaque
Every architectural decision is documented with rationale. We leave you with an environment you and your future hires can understand and modify.
Aegis Operational Continuity
The engineers who build the foundation can operate it under Aegis, or the foundation can be handed off cleanly to your team.

FAQs
Frequently Asked Questions
Common questions about AWS landing zone and foundation services.
How long does a typical landing zone engagement take?
For greenfield deployments, four to eight weeks from kickoff to an operational foundation. For existing AWS estates, six to twelve weeks depending on assessment scope and remediation complexity.
Do we have to rebuild our existing AWS accounts?
Usually no. We migrate posture in place where possible: enroll accounts into Organizations, apply SCPs, deploy Config and CloudTrail, update IAM patterns. Full rebuilds happen only when an account is so misconfigured that migration is more expensive than rebuild.
How does this integrate with our identity provider?
AWS IAM Identity Center federates with Okta, Entra ID, Ping, JumpCloud, Google Workspace, and generic SAML providers. We configure the integration, map your groups to permission sets, and build a baseline of least-privilege roles.
What about our existing on-premises network?
The landing zone networking foundation is designed to integrate with your existing on-premises network via Transit Gateway, Direct Connect, or SD-WAN. For enterprises that need full WAN modernization alongside the AWS foundation, we offer companion services.
Can we run this alongside a VMware-to-AWS migration?
Yes, and we frequently do. Landing zone work is a common prerequisite or parallel workstream for large migrations. The foundation provides the target environment for migrated workloads.
What does ongoing operations look like?
Foundations need ongoing care: new accounts, new SCPs, policy updates, security baseline evolution. We offer Aegis co-managed services for foundation operations, or co-managed models where your team owns day-to-day and we provide engineering depth for larger changes.
