Service overview
A growing AWS estate needs an account model that explains who owns each workload, where logs go and how teams obtain access. Clouvenix scopes landing zones for organizations moving beyond a single shared account. We review the existing AWS Organizations structure before proposing Control Tower adoption or changes. The engagement connects account provisioning, identity, network boundaries and operational ownership so application teams can use the foundation without relying on undocumented administrator actions.
When this service is useful
This engagement is useful when separate teams are creating accounts differently, privileged access is difficult to explain, or audit logs depend on individual administrators. It also fits a planned expansion into multiple business units. A landing zone provides a repeatable foundation; the discovery process checks whether that foundation can be introduced without disrupting existing workloads or central billing responsibilities.
Design and operating decisions
Account boundaries and shared ownership
We decide which workloads need separate accounts and which capabilities belong in shared security, logging or networking accounts. Organizational units should express an operating responsibility or policy difference. Creating more accounts without named owners and a workable request process can increase administration instead of improving control.
Guardrail rollout and recovery
Controls are introduced against a representative account before wider enrollment. We distinguish visibility controls from restrictions that can deny a deployment or administrative action. Recovery access, exception expiry and the people authorized to approve exceptions are recorded so a restrictive policy does not become an unexplained production blocker.
Scope and deliverables
- Account and organizational-unit ownership map
- Control Tower adoption and enrollment assessment
- Central logging and security account boundaries
- Federated permission-set and break-glass design
- Infrastructure code and account onboarding checklist
Delivery approach
1. Map the existing estate
Identify management-account dependencies, billing ownership, existing accounts and controls that could block workload deployment. Record exception owners before account enrollment.
2. Pilot the foundation
Build or adapt a nonproduction account path, test federation and logging, and introduce controls in a reviewed sequence with recovery access available.
3. Hand over account operations
Document account requests, permission changes, log access and emergency administration. Walk a workload owner through the onboarding process using an agreed example.
Illustrative engagement
Consider a company whose development and production workloads share an account, while a new team needs its own environment. A scoped pilot could establish the new account, federated roles and centralized logging first. The team then deploys one representative workload and follows the onboarding checklist. Existing workloads remain a separate migration decision. This example demonstrates the account request and operating process without suggesting that every legacy application must move during the foundation project.
Acceptance evidence
| Area | Evidence reviewed |
|---|---|
| Access | A named test user reaches only the approved account and role; recovery access is documented separately. |
| Governance | Selected controls produce the expected results and exceptions have an owner and review date. |
| Onboarding | An example account can be provisioned and connected to the agreed logging and network services. |
Before we start
Provide the account inventory, current identity provider, billing owner, security requirements and one representative workload team. Existing account restrictions and permission boundaries must be visible during discovery.
Planning the scope
The scope depends on account count, existing organization membership, identity-provider arrangements, network topology and how much infrastructure is already reproducible. Accounts with unusual restrictions or unmanaged resources may need preparation. We identify these conditions during discovery and separate foundational work from application moves, billing restructuring and ongoing operational coverage.
Handover and ownership
Handover includes the agreed account map, infrastructure repository, access procedures and a record of applied controls. We explain how an account is requested, who pays for it, who receives security findings and who can authorize a policy exception. A customer operator walks through those tasks so the handover is based on an executable process rather than diagrams alone.
Ongoing operations
After implementation, the foundation needs owners for account lifecycle, access reviews, control exceptions and platform updates. New services and business requirements can change the policy model. We recommend an agreed review cadence and a documented onboarding route, with operational support scoped around your team's coverage needs and escalation responsibilities rather than assumed to be unlimited.
Boundaries and support
Control Tower does not certify regulatory compliance. Account consolidation, application migration and organization-wide control enforcement require explicit approval and may be separate workstreams.
Frequently asked questions
Can you work with existing AWS accounts?
Yes. We first inspect current organization membership, account dependencies and supported enrollment requirements. The plan identifies accounts that need preparation instead of assuming every account can be enrolled unchanged.
Will application teams lose administrator access immediately?
Access changes are staged against an agreed role model. We test normal administration and emergency access before broad enforcement, and document any time-limited exceptions.
What happens after the foundation is delivered?
You receive account onboarding instructions, control ownership and operating records. Ongoing account administration or support coverage can be scoped separately around your team.
