Infrastructure as Code & CI/CD

How it works

From commit to production

Everything starts in Git: infrastructure definitions and application code. A pipeline builds and plans the change, showing exactly what will be created, modified or destroyed. Policy checks block insecure or non-compliant changes before deployment. Releases roll out safely with canary or blue/green strategies and automatic rollback.

Finally, drift detection compares what is running with what the code says, catching manual changes before they cause surprises.

Keyless pipelines

Pipelines need cloud access, but stored access keys are a top cause of breaches. All three clouds support OIDC federation: the CI system proves its identity and receives a short-lived token, so no secret is ever stored.

What makes each cloud different

Design decisions that matter

1. 01No console changes in production

   Read-only console access for people; changes only through pipelines.

2. 02Preview every change

   Require plan or what-if output in every pull request.

3. 03Policy as code before deploy

   Fail the pipeline on security and compliance violations.

4. 04Keyless pipelines

   Replace stored cloud keys with OIDC federation.

5. 05Small, reversible releases

   Use canaries and automatic rollback.

Common mistakes we see

• Click-ops in production. Undocumented changes break the next deployment.
• One giant state file. A single Terraform state for everything slows teams and widens blast radius.
• Secrets in pipeline variables. Long-lived keys leak; use federation and a secrets manager.
• No drift detection. Manual fixes silently diverge from code.

A practical 30-day plan

1. Week 1

   Pick the IaC tool and module structure; import critical resources.

2. Week 2

   Build the pipeline with plan, policy checks and approvals.

3. Week 3

   Switch pipelines to OIDC federation and remove stored keys.

4. Week 4

   Enable drift detection and lock production consoles to read-only.

How NTS helps

NTS sets up infrastructure as code and delivery pipelines on AWS, Azure and Google Cloud: module libraries, policy as code, keyless CI/CD, progressive delivery and drift detection. We also import existing hand-built estates into code without downtime.

How we work with you

1. 1Assess

   A focused review of your infrastructure as code and CI/CD across AWS, Azure and Google Cloud. We look for the gaps we find most often: click-ops in production, one giant state file, secrets in pipeline variables and no drift detection.

2. 2Design

   A target architecture and roadmap built on the decisions that matter most: no console changes in production, preview every change, policy as code before deploy, keyless pipelines and small, reversible releases.

3. 3Build

   Hands-on delivery alongside your team. We pick the IaC tool and module structure; import critical resources, build the pipeline with plan, policy checks and approvals, switch pipelines to OIDC federation and remove stored keys, and finally enable drift detection and lock production consoles to read-only.

4. 4Run and improve

   We maintain shared modules, pipeline templates and tool versions, and help teams adopt them across the organization.

Why teams choose NTS for infrastructure as code and CI/CD

• Everything as code

  We turn manual console work into reviewed, repeatable code that anyone on the team can run.

• Security built into the pipeline

  Policy checks and secret scanning stop problems before they reach production.

• Faster with guardrails

  Teams ship more often because every change follows the same safe path.
