Terraform and infrastructure as code services
Terraform and infrastructure as code services: Terraform and OpenTofu modules for AWS, Azure and Google Cloud, imports of infrastructure built by hand, plan and apply pipelines, state and drift management, policy as code, migrations from other tools, and Ansible for server configuration, with dedicated Terraform engineers for your team or an infrastructure-as-code project delivered end to end.
Infrastructure as code work we take on
Terraform modules
Reusable modules for networks, clusters, databases and identity, versioned in a private registry with examples, input validation and native Terraform tests, so every team builds the same way.
Plan and apply pipelines
A plan posted on every pull request and applied after review from GitHub Actions, GitLab CI, Atlantis, HCP Terraform or Spacelift, with the pipeline signing in to the cloud through OpenID Connect instead of stored keys.
State and drift management
Remote state with locking and encryption, split by environment and component so one apply cannot break everything, refactoring done with moved blocks, and scheduled drift detection that opens a ticket when something changes outside code.
Importing hand-built infrastructure
Resources created in the console brought under code with import blocks and generated configuration, then tidied until the plan shows no changes, without recreating anything that is running.
Ansible configuration management
Playbooks and roles for packages, users, hardening and application deployment on Linux and Windows servers and network devices, tested with Molecule and run from a pipeline or Ansible Automation Platform rather than from a laptop.
Policy as code and IaC scanning
Checkov, Trivy and TFLint on every pull request, and rules such as allowed regions, required tags and no public storage written in Open Policy Agent, Sentinel or cloud policy, so a non-compliant change fails before it is applied.
Terraform upgrades and OpenTofu moves
Old Terraform and provider versions upgraded step by step with every plan reviewed, and projects moved to OpenTofu where an open-source licence matters to you, with its state encryption switched on.
Migrations from other IaC tools
CloudFormation stacks, ARM templates, Pulumi programs and projects on CDK for Terraform, which HashiCorp archived in December 2025, converted to plain Terraform or OpenTofu, with state imported so nothing is recreated.
Secrets and short-lived credentials
Secrets kept out of variables and state: values read from Vault, OpenBao, AWS Secrets Manager or Azure Key Vault, ephemeral resources for values that only pass through, and cloud credentials that expire with each run.
Hire Terraform engineers
Dedicated Terraform engineers
Terraform engineers who join your team full time, work in your tools and process, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.
Infrastructure as code projects
A defined piece of infrastructure as code with a scope, a fixed plan and a named lead on our side who owns the result and reports progress in your channels.
Ongoing infrastructure as code
Infrastructure as code as a continuing service: the same people every month, a backlog you prioritise, and hours you can see in our portal and on the invoice.
The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.
Who works on your infrastructure as code

Pipelines and Ansible automation
Security engineers
Policy as code and plan reviews
How we write infrastructure as code
Nothing changes by hand: every change is a pull request with its plan attached, reviewed by a second engineer and applied by the pipeline, never from a laptop. Modules stay small and versioned, environments differ only in their variables, and state is split so a mistake affects as little as possible.
Our own company runs this way, with every resource in Terraform, applied from GitHub Actions with federated credentials and actions pinned by hash, and checked for drift on a schedule. On an estate built by hand or by another team, we start with a read-only review and a written list of risks, then import what exists before changing any of it.

Questions about Terraform and infrastructure as code
Which industries do your Terraform engineers work in?
Mostly fintech and banking, where every infrastructure change needs a review trail; cloud, hosting and telecom companies managing large estates as code; e-commerce and retail; enterprise SaaS, with an environment per customer or region; healthcare, with compliance controls written into modules; AI and data platforms; and security companies.
Terraform or OpenTofu?
Both read the same configuration, and most providers and modules work with either. Terraform comes with HCP Terraform and support from HashiCorp, an IBM company; OpenTofu is open source under the Linux Foundation and adds features such as client-side state encryption. We work in both and move projects between them.
Where does Ansible fit?
Terraform creates the infrastructure; Ansible configures what runs on it: packages, users, hardening and application settings on servers and network devices. Where workloads run in containers or serverless functions there is less for Ansible to do, so it is used wherever servers and devices remain.
How quickly can Terraform engineers start?
When the right Terraform engineer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire Terraform engineers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Want your infrastructure in code?
Tell us which clouds you use, how changes are made today and how much is already in code. You get an answer within one business day: a plan, candidate profiles, or a scope for a review of your Terraform.
