Automate Infrastructure, Reduce Errors
IaC replaces manual configuration with declarative or scripted code, allowing teams to provision, scale, and manage infrastructure consistently across environments.
What is IaC?
- Definition: Manage infrastructure (servers, networks, databases) using code instead of manual setup.
- Goal: Ensure reproducibility, consistency, and faster deployments.
- Types: Declarative (Terraform) or Imperative (Ansible, Chef).
Pros
- Eliminates configuration drift
- Enables automated, repeatable deployments
- Integrates with CI/CD pipelines
- Supports scaling infrastructure efficiently
Cons / Challenges
- Steep learning curve for teams new to IaC
- Requires version control and disciplined practices
- Mistakes in scripts can impact production
- Complex for hybrid or multi-cloud environments
Real-World Examples
- Terraform for cloud provisioning (AWS, Azure, GCP)
- Ansible or Chef for server configuration
- Automated database setup in staging & production
- Network and security group setup using code
Best Practices
- Store IaC scripts in version control
- Use modular, reusable templates
- Test changes in staging before production
- Document infrastructure and dependencies clearly
