Case Study - Infrastructure as Code for Test Environment Provisioning at a U.S. Credit Union

When Test Environments Became a Bottleneck

For a leading U.S. credit union with over $9bn in assets, testing was turning into an operational hurdle.

Their developers were spending more time setting up and troubleshooting test environments than actually testing features. Multiple teams had their own setup processes, cloud environments stayed active long after use, and manual configuration created inconsistencies that derailed releases.

This wasn’t about poor technical skills, it was about process inefficiency. Every test cycle came with delays, unexpected cloud spend, and growing frustration across engineering teams.

Objective:

To streamline test environment management through automation, reduce unnecessary cloud spend, and improve release reliability without disrupting active DevOps workflows.

WhiteBlue’s Approach and Solution Design

WhiteBlue began by mapping the credit union’s existing CI/CD workflows and environment provisioning steps. The findings were clear - provisioning was manual, governance was minimal, and cloud elasticity wasn’t being used effectively.

The team implemented an Infrastructure as Code (IaC) framework tightly integrated with the client’s DevOps pipelines. Environments could now be spun up automatically before tests and torn down immediately after. Security guardrails were embedded within scripts to maintain compliance.

In parallel, WhiteBlue conducted a cost audit and added governance automation to track and control cloud spend in real time.

Infrastructure as Code Implementation Journey

Instead of running a large-scale rollout, WhiteBlue adopted a phased narrative approach:

• Start small — one test environment automated end-to-end.

• Validate and monitor results.

• Gradually expand to all QA teams once patterns proved reliable.

• Enable audit and cost-monitoring dashboards as the final step.

Each phase improved speed, reliability, and cloud optimization, making testing faster and cleaner.

Results

• 70% reduction in environment costs

• 20% improvement in test repeatability

• Zero provisioning errors post-automation

• Fully auditable and compliant infrastructure provisioning
