Infrastructure as Code and Managed Cloud Services

Reproducible environments and a cloud estate someone actually runs.

About Infrastructure as Code & Managed Cloud

Infrastructure that exists only in a console is infrastructure nobody can reason about. Nobody knows why a security group has that rule, whether staging matches production, what would happen if the account were lost, or how long it would take to rebuild. Infrastructure as Code fixes this by making the environment a reviewable, versioned, testable artefact — and by making drift visible instead of invisible.

We write infrastructure in Terraform or Pulumi with a module structure that is composable rather than copy-pasted, remote state with locking and a clear blast-radius boundary per stack, and policy-as-code guardrails using OPA or Sentinel so a plan that would open a public bucket or launch an oversized instance fails in CI rather than in production. Every change goes through the same pull request and review flow as application code, with plan output attached so reviewers see exactly what will change.

Where you would rather not run the estate at all, we operate it. Managed cloud covers 24/7 monitoring with on-call rotation, patching and upgrade cadence, backup with genuinely tested restores rather than assumed ones, cost review, security posture management, and an incident process with defined response times. You get a monthly report that covers availability against SLO, cost against budget, security findings and remediation, and the change log.

The engagement is explicitly reversible. Everything lives in your cloud accounts and your repositories, and the runbooks are written for someone who did not build it. If you later hire a platform team, they inherit a working estate and a clear handover — not a black box.

Why it matters

What you get

Reproducible environments

Production, staging and preview built from the same modules with different inputs, so environment drift is a caught diff rather than a mystery bug.

Guardrails enforced in CI

Policy-as-code blocks public buckets, unencrypted volumes, oversized instances and missing tags before the plan ever applies.

Disaster recovery you have actually tested

Documented RTO and RPO targets, automated backups, and scheduled restore drills — because an untested backup is a hypothesis.

24/7 operations with real response times

On-call rotation, defined severity levels and contractual response targets, with blameless postmortems for anything that reaches production.

No lock-in to us

Your accounts, your repositories, your credentials. Runbooks are written for a stranger, so handover is a scheduled event rather than a negotiation.

How we deliver

Our process for this work

Adapted to this service specifically — not a generic five-box diagram.

  1. 01

    Estate audit

    1–2 weeks

    Inventory of existing resources, drift detection against any current code, security posture review and a documented risk register.

  2. 02

    Codify

    3–6 weeks

    Existing infrastructure imported into modules, state structured by blast radius, and environment parity established across stages.

  3. 03

    Guardrails & pipelines

    2–3 weeks

    Plan and apply automation, policy-as-code checks, cost estimation on pull requests, and drift detection on a schedule.

  4. 04

    Operational readiness

    2–4 weeks

    Monitoring and alerting against SLOs, backup and restore drill, incident runbooks, and on-call rotation established.

  5. 05

    Managed operations

    Ongoing

    Patching, upgrades, incident response, monthly availability and cost reporting, and continuous security posture management.
