Ansible IaC Automation CIS
Ansible's agentless, idempotent execution model means every playbook run converges infrastructure to a known, documented state — and does nothing when that state is already correct. We build role-based playbook libraries, CIS-benchmark hardening pipelines and AWX-driven automation for US and EU clients who need config management that is testable, version-controlled and ready for compliance audits.

Challenges
Tasks that use shell or command modules bypass Ansible's idempotency guarantees, causing unintended re-execution on repeated runs. We audit every playbook for non-idempotent tasks and replace them with purpose-built modules or custom idempotent logic.
Storing secrets in plaintext vars files or passing them via the command line creates audit and rotation risk as inventories grow. We implement ansible-vault for at-rest encryption and integrate HashiCorp Vault for dynamic, short-lived credentials across all environments.
Static inventories fall out of sync with dynamic cloud environments, causing playbooks to miss new hosts or target decommissioned ones. We replace static files with dynamic inventory plugins (AWS EC2, Azure, GCP, Terraform state) so the host list always reflects the live infrastructure.
Flat playbooks grow into hard-to-read monoliths with duplicated tasks and environment-specific conditionals that block reuse. We refactor monolithic playbooks into role-based libraries with clear interfaces, default variables and Galaxy-publishable structure.
Ansible roles are often deployed untested, surfacing failures on production nodes rather than in CI. We enforce Molecule test scenarios with Docker or Vagrant drivers and ansible-lint checks on every pull request.
Manual changes applied directly to servers diverge from the declared Ansible baseline, creating invisible risk and breaking future playbook runs. We schedule periodic idempotent runs via AWX and alert on changed-task count spikes that indicate unreported drift.
Solutions
Modular Ansible roles with clean variable interfaces, documented defaults and Galaxy-compatible structure — reusable across projects, environments and cloud providers.
Turnkey CIS Benchmark roles for RHEL, Ubuntu and Amazon Linux applied on every provision — Level 1 or Level 2 per client policy — with molecule-tested idempotency.
ansible-vault for at-rest variable encryption combined with HashiCorp Vault dynamic lookups — no plaintext secrets in Git, automated rotation without playbook changes.
Every role ships with Molecule scenarios (Docker driver for speed, VM driver for accuracy), ansible-lint clean checks and CI gates — failures surface in pull requests, not production.
AWS EC2, Azure Resource Manager and GCP inventory plugins replace static files — hosts are discovered automatically, tagged, grouped and targeted without manual inventory maintenance.
AWX / Ansible Automation Platform schedules daily idempotent baseline runs, logs every job with full task-level detail, alerts on unexpected changes and provides RBAC-controlled self-service for operations teams.

Why YuSMP
Ansible connects over SSH and WinRM — no agent to install, patch or secure on managed nodes. Onboarding a new host requires only network access and a user with sudo rights.
AWX job logs, Git-tracked playbooks and ansible-lint reports give auditors the change history, approvals and configuration proof they need without additional tooling.
Our role library covers OS hardening, user management, package pinning and service configuration — clients inherit tested building blocks rather than starting from blank playbooks.
FAQ
Terraform provisions infrastructure resources — VMs, networks, databases, DNS records. Ansible configures what runs on those resources — OS settings, packages, users, services and application config. The two tools are complementary: Terraform creates the node, Ansible hardens and configures it. We use Terraform output as Ansible dynamic inventory so the handoff is automatic and the state stays consistent across both tools.
Ansible connects to managed nodes over SSH (Linux/macOS) or WinRM (Windows), pushes a temporary Python module, executes it and removes it. There is no persistent daemon or agent to maintain. The control node needs SSH access and a privilege-escalation user on each target. This model makes onboarding fast — a new host is reachable the moment SSH is open — and eliminates a class of agent-patching and connectivity problems seen in agent-based tools.
We use two layers. ansible-vault encrypts variable files at rest using AES-256 so secrets are safe in Git. For dynamic, short-lived credentials — cloud API keys, database passwords, TLS certificates — we integrate HashiCorp Vault via the community.hashi_vault lookup plugin. Vault issues short-lived secrets at playbook runtime; they never touch disk. The vault password itself is stored in a secrets manager and injected into AWX as a credential, keeping the full chain encrypted.
Idempotency means running a playbook ten times has the same effect as running it once: tasks that are already in the desired state report "ok" and change nothing. This matters because it makes playbooks safe to re-run for drift remediation, lets you schedule daily baseline runs without side effects and simplifies troubleshooting — a changed-task count above zero immediately indicates real drift. We audit every role for non-idempotent shell and command tasks and replace them with idempotent module equivalents.
We use Molecule, the de facto testing framework for Ansible roles. Each role ships with at least one Molecule scenario: a Docker-based scenario for fast feedback in CI and, for roles that require systemd or kernel features, a VM-based scenario run on a schedule. ansible-lint checks style and common mistakes on every pull request. Test scenarios cover converge (apply), idempotency (re-apply, expect zero changes) and optionally verify (assert the end state). No role reaches production without a green CI run.
AWX (open source) and Ansible Automation Platform (Red Hat's commercial product) add a web UI, REST API, RBAC, credential vault, job scheduling and full execution logs on top of Ansible Core. Teams trigger playbook runs from a self-service portal or CI webhook without needing CLI access. RBAC limits each team to the playbooks and inventories relevant to them. Job logs with task-level detail satisfy SOC 2 evidence requirements. We deploy AWX on Kubernetes for high availability and integrate it with your existing LDAP or SSO provider.
CIS hardening roles apply the configuration controls from the CIS Benchmark for a given OS — RHEL, Ubuntu, Amazon Linux or Windows Server. Each control maps to one or more Ansible tasks that check and enforce the required setting: kernel parameters, filesystem mount options, service enablement, PAM configuration, SSH daemon settings, audit rules and package lists. Controls are tagged so individual items can be skipped for documented exceptions. We test every role with Molecule to confirm CIS controls apply cleanly and idempotently, and we produce a machine-readable report of applied vs skipped controls for auditors.
