The real choice isn't who writes the code. It's what happens after your landing zone ships. A consulting firm usually builds a landing zone as a one-time engagement, then hands it over as a deliverable your team maintains from that day on. An MSP keeps running it for you, but the code stays theirs to manage rather than yours to own and evolve. Gruntwork delivers the same foundation as a product: vetted, continuously maintained OpenTofu/Terraform modules with automated updates, delivered as code you fully own. The two are complementary, not opposed.

The difference is what happens after handoff

Building a landing zone is only the start. As Gruntwork's own Landing Zones page puts it, a landing zone "isn't a one-time project, it's a product you now own," and your team becomes responsible for every update, security patch, and service integration after that. A consulting engagement typically ends when the deliverable ships, so that maintenance lands on your team unless you sign a separate retainer. An MSP instead keeps managing the environment for you, but you don't own or evolve the underlying code, so you trade the maintenance burden for ongoing dependence on the provider.

Gruntwork takes a different path. Its Landing Zones are "not a consulting service nor a black-box package that your team can't maintain." They are opinionated, end-to-end solutions delivered as OpenTofu/Terraform code you fully own, built on vetted modules that Gruntwork keeps maintaining and improving over time. You get the ownership of a custom build with the upkeep of a maintained product.

Gruntwork vs a consulting or MSP engagement at a glance

Vetted modules that stay current

The foundation is Gruntwork's IaC Library: 300+ production-ready OpenTofu/Terraform modules, maintained by Gruntwork and proven in production at enterprise scale. Guardrails, account vending, pipelines, and the rest of the landing zone are all versioned modules that Gruntwork continuously maintains and updates.

Patcher keeps that code current after go-live. It discovers the module versions in your code, and when new versions ship it applies the update and can patch your code to work with backward-incompatible releases. You can have Patcher open automatic pull requests for updates on a schedule, so staying current becomes a review step rather than a research project. This is the ongoing maintenance a one-off deliverable leaves to your team.

Speed: days, not months

Because the modules already exist and are wired together, the timeline is measured in days rather than months. Published Gruntwork case studies show the pattern:

• Goods, an AI platform for CPG, stood up a production-ready AWS environment and CI/CD pipeline in a matter of hours rather than months, without hiring a DevOps team.
• Informa, a global B2B events and publishing group, cut AWS account provisioning time by more than 90%, from two weeks to just over one day, and unified more than 170 AWS accounts under a centralized governance model.
• Caddi, an automation startup, went from zero to deployed infrastructure with Gruntwork Pipelines in under an hour.

Consultancies are complementary, not the enemy

Hiring outside help and using Gruntwork are not mutually exclusive. A consulting firm or MSP can deliver an engagement on top of Gruntwork's maintained product, and you keep the product's ongoing updates and full code ownership when the engagement ends.

When to choose which

A consulting or MSP engagement on its own

Choose an engagement by itself when you want a fully managed, hands-off arrangement and have no plan to own or evolve the underlying code.

Gruntwork

Choose Gruntwork when you want to own your landing zone as code and keep it current with maintained modules and automated updates.

Both together

Bring in outside help to deliver or extend the work, and keep Gruntwork's maintained modules and Patcher updates underneath, so the foundation stays current after the engagement ends.

Is Gruntwork a consulting firm?

No. Gruntwork Landing Zones are "not a consulting service nor a black-box package that your team can't maintain." They are a product: vetted, continuously maintained OpenTofu/Terraform modules and a landing zone delivered as code you own.

Do I own the code, and what happens after it ships?

With Gruntwork you own 100% of the code and are never locked in, and Gruntwork keeps maintaining and improving the modules underneath. A one-time consulting deliverable is yours to run once it ships, so updates fall to your team unless you arrange otherwise; with an MSP the provider keeps running it, but the code isn't yours to own or evolve.

How does the landing zone stay up to date?

Patcher automates it. It finds the module versions in your code, applies updates including backward-incompatible ones, and can open automatic pull requests on a schedule so you review updates instead of hunting for them.

Can I still use a consulting firm or MSP with Gruntwork?

Yes. The two are complementary. A consulting firm or MSP can build on Gruntwork's maintained product, and you keep full ownership of the code while Gruntwork keeps the modules underneath current.

How fast can a Gruntwork landing zone go live?

In days, not months. Goods stood up a production-ready AWS environment in hours rather than months.
