Infrastructure as Code Implementation

The Problem: Configuration Drift

A media streaming service was struggling with "configuration drift." Their development, staging, and production environments had diverged significantly over time due to manual updates and ad-hoc fixes. This led to the "it works on my machine" syndrome, where code that passed testing failed in production.

The Solution: IaC

We introduced Terraform to provision the cloud infrastructure (VPCs, EC2 instances, Load Balancers, RDS) and Ansible for configuration management (installing software, patching, managing config files).

Modular Design

We created reusable Terraform modules for common infrastructure patterns. This allowed developers to spin up compliant infrastructure components without needing deep knowledge of the underlying cloud provider settings.

Automated Provisioning

We integrated Terraform into the CI/CD pipeline. Any change to the infrastructure code triggered a `terraform plan` to preview the changes, followed by a `terraform apply` upon approval. This ensured that all changes were reviewed and audited.

Results

The adoption of IaC brought order to the chaos:

• Consistency: Environments became identical, eliminating deployment surprises.
• Speed: Provisioning a new environment for load testing now takes minutes instead of days.
• Disaster Recovery: The entire infrastructure can be recreated from scratch in less than an hour in a different region if needed.
