BuiltForProd by Nexstella
A cloud foundation in your accounts, with the source
A multi-account cloud foundation separates workloads, identity, logging and networking into accounts with guardrails written as code. BuiltForProd, Nexstella's production engineering brand, deploys one into your own accounts, verifies it and hands over the repositories.
01 How we work
Why a foundation is worth building once
-
Account boundaries limit the damage
When production, staging and shared services live in separate accounts, a mistake or a leaked credential in one place stays there instead of reaching everything else you run.
-
Guardrails sit above every team
Organization policies block the risky moves for everyone, including administrators, so safety does not depend on each engineer remembering the rules on a busy day.
-
The code is the documentation
Accounts, networks and permissions are defined in OpenTofu and Terragrunt. A reviewer reads a pull request to see what changed, and a new hire reads the repository to see how it all fits.
-
You keep it when we leave
The accounts are created in your name and the repositories are handed over. After handover BuiltForProd keeps no standing access to your environment.
What we'll tell you
A foundation is the part of production that is cheap to build early and costly to retrofit. It does not fix application code, and it is more than a prototype needs.
Account map
What the foundation sets up, account by account
In the AWS Enterprise Baseline, 14 accounts sit in 2 organizational units under 3 service control policies. Pick an account, a network piece or a guardrail to see the job it does.
Organization
-
Management account
Owns the organization, billing and the guardrail policies, and runs no workloads of its own.
-
Identity
Single sign-on for every account, with permission sets instead of personal users and keys.
-
Audit
Receives the organization's logs, where auditors can read the controls but not your data.
Shared services
-
Security
Runs the threat detection and findings services for the whole organization from one place.
-
Network
Holds the hub network that every workload account connects through.
-
Artifacts
Stores built images and packages, so what runs in production is the artifact that was tested.
Workloads
-
Sandbox
A place to try things that is walled off from everything that matters.
-
Dev and staging
Built from the same template as production, so a change is proven before it ships.
-
Prod
Read-only for almost everyone, and changed only through the pipeline after review.
Guardrails
-
No personal users or keys
An organization policy blocks long-lived credentials, so access always goes through sign-on.
-
Approved regions only
Resources can be created only in the regions you chose, which keeps data where you expect it.
-
Logging stays on
Audit logging cannot be switched off from inside an account, even by its administrator.
How it starts
-
Talk through your accounts
On a 30-minute call with an engineer you describe the cloud you run on, the accounts you have and what is coming next, such as an audit, a large customer or a launch.
-
Agree the edition and the option
You get a written scope that names the edition and the deployment option, the decisions needed from your side, and a fixed fee quoted before any work starts.
-
Deploy phase by phase
Engineers deploy the foundation into your accounts in dependency order, with production changes gated by reviewers you name, then run the verification checks.
-
Hand over the source
Your team receives the repositories, the runbooks and a handover session, so you can extend the foundation yourselves or ask for help later.

Book a call with BuiltForProd02 A typical situation
What this usually looks like
Picture a software company that still runs everything in the one cloud account a founder opened years ago. Developers share an administrator login, test data sits next to customer data, and a new enterprise customer has sent a long list of questions about access and isolation.
We would split the estate into accounts with clear jobs, move access onto single sign-on and put guardrails above every account. Workloads would move over one at a time, starting with the least risky, and the team would get the code and the runbooks to carry on without us.
03 Questions
Questions people ask
BuiltForProd offers three editions: the AWS Enterprise Baseline, the Azure Enterprise Baseline and the GCP Enterprise Baseline. On the call, the engineer talks through the edition that matches the accounts you already have.
No. The foundation is finished, tested code, and the engagement is BuiltForProd engineers adapting it to your organization and deploying it into your accounts. You receive a running, verified setup and the source that built it.
Yes. The code is source-available, written in OpenTofu and Terragrunt, and your copy lives in your own repositories. Changes go through pull requests like any other code your team owns.
It gives a reviewer something concrete to look at: separated accounts, sign-on instead of shared logins, logs that cannot be switched off and guardrails written as code. Whether a review is passed is never ours to promise.
