An AWS landing zone is a pre-built, governed multi-account foundation: the account structure, identity, network baseline, logging and guardrails that everything else gets built on top of. AWS recommends multiple accounts rather than one, because an account is the strongest isolation boundary AWS gives you. Building it first is cheaper than retrofitting it, because once workloads, data and access policies are tangled together in one sprawling account, separating them means re-architecting under production load and reconstructing the evidence an auditor will ask for after the fact.
Built once, inherited everywhere.
Everything here is configured once at the organisation level and inherited by every account you create afterwards. That is the whole point: the guardrails should not depend on the next engineer remembering them.
A management account at the top, a security organisational unit holding the log archive and audit accounts, a sandbox organisational unit for experiments, and separate accounts for production and non-production workloads. The account boundary is the isolation you actually get to rely on, so we spend real time on this layout rather than defaulting to a template.
AWS Control Tower gets you a governed landing zone quickly, with shared accounts, controls and centralised logging set up for you. Where its opinions do not fit your required structure, we build the equivalent in Terraform instead, kept in the same code and review process as the rest of your infrastructure. See our Terraform and IaC page for how that side runs.
People sign in once and assume scoped roles into the accounts they are entitled to, instead of collecting long-lived access keys per account. Permission sets are defined centrally and mapped to your existing directory where you have one. This is the control that makes offboarding a single action rather than an archaeology exercise.
CloudTrail and AWS Config logs from every enrolled account land in a central bucket in the log archive account, which is deliberately kept out of reach of the teams whose activity it records. Those logs are retained for audit and investigation and are not editable by the accounts that produced them, which is exactly the property an auditor is testing for.
Preventive controls use service control policies to refuse the action outright. Detective controls use AWS Config rules to flag drift after the fact. Proactive controls use CloudFormation hooks to block non-compliant resources before they are provisioned. We decide with you which belong in each category, because enforcing everything on day one tends to end with someone quietly turning it all off.
Consistent VPC design across accounts, private subnets for anything that does not need to be reachable, deliberate egress control so workloads cannot quietly talk to the whole internet, and a plan for how accounts reach shared services. Getting the address plan right early avoids the overlapping CIDR ranges that make later connectivity painful.
Separate accounts are the cleanest cost boundary AWS offers, so a landing zone gives you per-team and per-environment spend for free if the structure and tagging policy are set up properly. Budgets and alerts are configured at the organisation level. Ongoing cost discipline lives on our FinOps page.
A landing zone is only worth building if account number twelve comes out the same as account number three. We set up account vending so a new account arrives already enrolled, already logging, already governed by the right guardrails, and already wired into single sign-on, rather than being hand-assembled by whoever was free that week.
Most compliance frameworks ask the same underlying questions: who can reach what, can you prove what happened, and is production separated from everything else. A landing zone is where those answers get built, which is why it is much cheaper before an audit than during one.
Both lean heavily on access control, change tracking and logging. Centralised, tamper-resistant CloudTrail across every account, single sign-on with scoped permission sets, and guardrails that are enforced rather than documented turn a long list of Annex A and Trust Services questions into configuration you can show. See ISO 27001 on AWS and SOC 2 on AWS.
The cheapest way to reduce the cost of a PCI DSS assessment is to make less of your estate in scope. An account boundary is the clearest separation AWS gives you for that argument, which is a good deal easier to defend than network segmentation inside one shared account. See PCI DSS on AWS.
Financial-sector rules push hard on knowing your dependencies, containing blast radius, and evidencing that you can recover. Separated accounts with explicit connectivity make the dependency map real rather than aspirational, and they mean one compromised workload cannot reach the rest. See DORA on AWS.
Where residency matters, a preventive guardrail at the organisation level can refuse resource creation outside approved regions, which is a far stronger answer than a policy document asking people not to. This is how residency commitments stop depending on everyone remembering them. See GCC data residency.
A landing zone is foundation work, so the timing question matters more than the technical one. There are three points where it clearly pays, and one where it clearly does not.
You are adopting AWS properly for the first time. This is the cheapest possible moment, because there is nothing to untangle and no production traffic to plan around. Everything built afterwards inherits the structure automatically.
If a migration is coming, the landing zone goes first. Moving workloads into a governed structure costs the same as moving them into a flat account, and it saves doing the whole thing twice.
AWS migrationThe common case. Accounts were created as needed, access spread, and nobody can now answer who can reach production. More work than greenfield, and still worth doing before the estate gets any larger.
This is foundation work with a defined end, not an open-ended retainer. You should be able to run it without us.
We agree the account structure, guardrails and identity model with you in writing, build it, and hand it over with documentation covering what exists, why each decision was made, and how to add the next account. Pricing is quoted after a free scoping call, with a fixed scope and a fixed quote before any work begins. No open-ended hourly meter.
A landing zone drifts like anything else once people start using it. If you want it monitored, patched and kept aligned rather than slowly eroding, our CloudOps retainer is the parent service that operates what the landing zone establishes. Plenty of clients take the build and run it themselves, which is a perfectly good outcome.
An account structure is hard to change once workloads sit on it, so the design call matters more than the build.
Partner tier is public and verifiable, and it reflects certified staff and delivered work rather than a logo on a website. You can check it before you talk to us.
The people designing your account structure and writing your guardrails are AWS-certified engineers, stated at team level. We do not hand foundation work to whoever is free.
The founder attends engagement calls, so the person accountable for the company is in the room when the account design is agreed, not a salesperson who hands you on afterwards.
If your question is not here, ask it on the call. We would rather talk you out of a landing zone you do not need than build one you will not use.
Bring what you have on AWS now and what you expect in two years. You will leave with a view of the account structure that fits, and an honest answer on whether you need a landing zone yet. If you do, the scope and the quote are fixed before anything is built.
