Terraform · Ansible · IaC

From handcrafted servers
to Infrastructure as Code.

Eliminate human error, audit every change, and deploy complete environments in minutes, not weeks. We master the ultimate duo: Terraform to provision, Ansible to configure.

The Problem

What handcrafted infrastructure costs your team.

It's not a tooling problem. It's a process problem. These symptoms appear in almost every team that still manages servers manually or with fragile scripts.

01

The Snowflake Server Syndrome

You have 50 servers that are supposed to be identical, but each has slightly different configurations, hand-applied over the years by different people. Code works in QA but explodes in Production — and nobody knows exactly why. Every server is unique, fragile, and hard to replace. Impossible to scale.

02

The Magic Script Debt

Your current "automation" depends on a 2,000-line Bash script written by an admin who no longer works at the company. Nobody dares touch it because nobody knows what it will break. Code gets piled on top of code, broken parts get commented out. Operations technical debt grows silently — until one day the script fails in production at 2 AM.

03

The Critical Patch Panic

A zero-day vulnerability with CVSS 9.8 drops. Manually updating and restarting 200 virtual machines takes days — or weeks if the team is small. During that window the company is exposed. Compliance audits ask: when were all servers patched? The honest answer is: we're not sure exactly.

04

Server Onboarding Chaos

Every new server gets configured by whoever has time that day, following an outdated wiki or from memory. No standard baseline, no audit trail, no way to verify that the server complies with the company's security policies. The attack surface grows with every server added, and documentation always lags behind reality.

The Solution

The ultimate synergy:
Terraform builds, Ansible configures.

The most common question: why do I need both tools? Because they solve different problems — and together they cover 100% of the infrastructure lifecycle.

The Builder
Terraform

Declarative and idempotent. Terraform describes in code what infrastructure should exist — and creates, modifies, or destroys it so the real state matches the code. A single terraform apply can rebuild your entire environment from scratch.

  • VPCs, subnets and firewall rules on AWS, Azure or VMware
  • Virtual machines, load balancers, DNS
  • Kubernetes clusters and managed databases
  • Shared state in S3/GCS — infrastructure as a team
HCLStateProvidersAWS / Azure / VMware
The Configurator
Ansible

Agentless and frictionless. Ansible enters servers via SSH and furnishes them: installs packages, configures services, applies security policies, manages users. No agents required. Playbooks are readable YAML — any team member can understand and audit them.

  • Installation and configuration of Nginx, PostgreSQL, Java, etc.
  • CIS Benchmarks Level 1 and 2 (Linux and Windows)
  • User management, SSH keys and permissions
  • Mass patching of hundreds of servers in parallel

Consulting

What does our service include?

Three maturity levels. We start where you are — not where we think you should be.

Foundation

IaC Foundation
with Terraform

We codify your current infrastructure. We move your environment from console clicks to versioned Git repositories.

  • Discovery and modeling of existing infrastructure
  • Terraform modules for your critical resources
  • Remote state backend (S3, GCS or Azure Blob)
  • CI/CD pipeline for terraform plan on every PR
  • Documentation and handover to the internal team
Hardening

Standardization & Hardening
with Ansible

We create the standard configuration baseline for all your servers and apply it automatically, every time.

  • Ansible Roles for web servers, databases and applications
  • CIS Benchmarks Level 1/2 for Linux (RHEL, Ubuntu) and Windows
  • User management, SSH keys and sudoers via code
  • Scheduled mass patching and compliance reports
  • Molecule for automated role testing
Enterprise

Ansible Automation Platform
AWX / Red Hat AAP

For large teams. A centralized platform where Playbooks run with full control without exposing credentials.

  • Deployment and configuration of AWX or Red Hat AAP
  • RBAC: access control by role and team
  • Secure delegation: a dev restarts a service without SSH access
  • LDAP/AD and corporate SSO integration
  • Approval workflows for critical production changes

The Business Case

Why IaC is not just "saving time"?

"Most companies have automation. Few have immutable, auditable, and reproducible infrastructure. The difference isn't the tool — it's knowing how to combine Terraform and Ansible so every production server is identical to what the Git repository describes."

01

Real Disaster Recovery

If the primary Data Center goes down, standing up the failover site means running terraform apply and ansible-playbook. RTO drops from days to hours — or less. Infrastructure doesn't depend on anyone's memory: it's in the code.

02

Continuous Compliance

Audits stop being a race against time. Every server's configuration is documented in Git — that's the Single Source of Truth. Any deviation is detectable with an Ansible scan. The compliance report is generated by the code, not a person.

03

Zero Operational Vendor Lock-in

Terraform and Ansible are cloud and hypervisor agnostic. If tomorrow you migrate from VMware to AWS, the configuration logic and CI/CD workflow stay the same. The knowledge lives in the company's Git repositories — not in a vendor's head.
