OpenTofu Atlantis SOC 2-ready Multi-cloud

Terraform Engineering Services for Reproducible, Auditable Infrastructure

Twenty-plus production infrastructure stacks managed with Terraform — ANT on AWS EKS, REHAU's multi-region B2B portal, Loan Conveyor's lending engine on RDS and ElastiCache. Every resource is code, every change is a PR, every apply is logged. No manual console configuration enters production.

We deliver Terraform and OpenTofu engineering for teams replacing manual cloud configuration with code, regulated industries where every infrastructure change must be traceable for SOC 2 or ISO 27001 audits, organisations standardising on multi-cloud stacks across AWS, Azure and GCP, and platform teams building reusable module libraries for product engineering teams. Atlantis handles pull-request-based plan and apply. Terragrunt eliminates DRY violations. Sentinel policies enforce compliance guardrails.

Challenges

Industry challenges we solve

State file corruption and locking

Concurrent applies on shared state corrupt it irreversibly. We set up S3 + DynamoDB or Terraform Cloud backends with locking enforced from the first day.

Monolithic stacks with slow plans

Single-state files covering an entire environment take 10+ minutes to plan. We split by subsystem (network, compute, data, app) for sub-minute plans and minimal blast radius.

Drift from manual console changes

Developers fixing incidents by clicking in the console create drift that breaks the next Terraform apply. We implement AWS Config alerts and Atlantis drift detection.

Module version sprawl

Teams using unpinned module sources diverge silently. We implement a private module registry with semantic versioning and enforce version pins in CI.

Secrets in Terraform state

Sensitive outputs (database passwords, API keys) land in state files in plaintext. We use AWS Secrets Manager or Vault data sources — values never stored in state.

SOC 2 evidence gaps

Auditors want proof that every infrastructure change was reviewed and approved. We route all Terraform applies through Atlantis PRs with plan output and approval comments — a full evidence trail.

Solutions

Solutions we build

Greenfield IaC setup

Remote state backend, Atlantis PR workflow, module structure, variable convention and tagging strategy — all in place before the first resource deploys.

Multi-cloud module libraries

Reusable modules for EKS/AKS/GKE, RDS/Azure SQL, VPC/VNet, IAM/Entra — versioned in a private registry, documented and tested with Terratest.

SOC 2 and ISO 27001 evidence pipelines

Every Terraform apply flows through a PR with plan, approval and apply log stored in Git and exported to your compliance evidence repository.

Legacy infrastructure migration

Converting hand-configured AWS/Azure resources to Terraform using import blocks and terraformer — zero downtime, with state validation at each step.

Drift remediation

Auditing an existing environment for console-created resources, importing them into state, and establishing Atlantis to prevent future drift.

Terragrunt DRY refactors

Collapsing environment-duplicated Terraform into Terragrunt configurations with shared modules and per-environment variable files.

Compliance

Compliance & regulations

GDPR-aligned · SOC 2-capable · ISO 27001-ready · PCI DSS-aware

EU

  • GDPR — data residency enforced via Terraform variable sets.
  • ISO 27001 — change control evidence via PR-based applies.
  • NIS2 — infrastructure configuration as verifiable security control.
  • DORA — reproducible DR infrastructure via IaC.

US

  • SOC 2 Type II — full change trail in Git + Atlantis apply logs.
  • HIPAA — encryption, network segmentation enforced in code.
  • PCI DSS — network controls and security group rules in version control.
  • FedRAMP-adjacent — FIPS endpoints and GovCloud configs in Terraform.

Shared: Checkov and tfsec policy scans in CI, Sentinel policy as code, SBOM for provider versions.

Why YuSMP

Why infrastructure teams choose YuSMP

PR-only applies enforced

No engineer has direct terraform apply access to production. Atlantis enforces plan-review-apply via Git pull requests — every change is reviewed and logged.

Policy-as-code from day one

Checkov, tfsec and Sentinel policies block non-compliant resources before they apply — not after the audit flags them.

Multi-cloud, one workflow

AWS, Azure and GCP providers in the same Terragrunt monorepo — consistent PR workflow, module versioning and tagging across clouds.

FAQ

Terraform FAQ

Terraform or OpenTofu — which do you use?

Terraform for clients with existing HashiCorp tooling or Terraform Cloud subscriptions. OpenTofu (the BSL-free fork) for new greenfield projects and clients who want to avoid HashiCorp's BSL licensing changes. Both use identical HCL syntax — migrating between them requires only a state backend configuration change.

How do you prevent Terraform state corruption in teams?

Remote state in S3 (with DynamoDB lock table) or Terraform Cloud for AWS workloads, Azure Blob Storage for Azure. State locking prevents concurrent applies. We also separate state per environment (dev/staging/prod) and per major subsystem to minimise blast radius of failed applies.

How do you handle Terraform drift?

Scheduled terraform plan in CI detects drift from out-of-band console changes. Atlantis flags drift in pull request comments. For critical resources we use AWS Config or Azure Policy to alert on manual changes in real time. Terraform Sentinel policies block non-compliant resources from being applied.

Terragrunt or raw Terraform modules?

Terragrunt for DRY multi-environment configurations where you call the same module with different variable files per environment — avoids the variable repetition problem in flat Terraform. Raw modules for simpler stacks where Terragrunt's abstraction adds more complexity than it removes.

How does Terraform support SOC 2 evidence?

Every infrastructure change goes through a PR with plan output, human approval and apply log — stored in Git forever. We pipe Terraform run history and policy check results to your SOC 2 evidence repository. AWS CloudTrail confirms what Terraform actually created, giving auditors the source-of-truth and the confirmation.

How do you manage Terraform for multi-cloud environments?

We use provider version pinning, separate state backends per cloud, and a module naming convention that makes the provider obvious at a glance. Shared modules (tagging, DNS, monitoring) are provider-agnostic. Cloud-specific modules (EKS vs AKS vs GKE) are named and versioned separately.
