Infrastructure as code: declarative, versioned and auditable
Infrastructure as code (IaC) means defining infrastructure through declarative, versioned files —with tools such as Terraform, Ansible or Pulumi— instead of configuring it by hand. The desired state is described in code, reviewed like any software change and applied reproducibly, leaving an auditable trail of what was changed, when and by whom.
What it brings
- Reproducibility — the same code stands up identical environments, eliminating drift between development, staging and production.
- Change control — infrastructure is reviewed, approved and versioned like code, with a full history in the repository.
- Auditable evidence — every change is recorded and traceable, which makes it easier to demonstrate control to the supervisor.
- Recovery — rebuilding an environment after an incident no longer depends on one person's knowledge and becomes a repeatable operation.
Why it matters in banking and insurance
In a regulated environment, infrastructure configured by hand is a risk: drift, dependence on specific individuals and no trail. IaC turns provisioning into something reproducible and reviewable, with auditable evidence of every change. That fits directly with the change-management and recovery discipline that DORA expects, and it is also the operational foundation that underpins the reversibility of hybrid and multicloud architectures: if the infrastructure is in code, recreating it on another provider stops being a project.
