CI/CD Case Study

Accelerating Software Delivery with Continuous Integration and Continuous Delivery

About the Project

In a fast-paced digital market, software updates must reach users quickly, reliably, and with minimal risk. A leading financial technology company approached Spundan to modernize its software delivery pipeline. The client manages a complex suite of applications — spanning microservices, APIs, and customer-facing web portals — serving millions of users across banking and insurance products.

Their legacy release process relied heavily on manual testing, approvals, and handoffs, leading to slow release cycles, frequent deployment errors, and delays in delivering new features. The leadership recognized that to stay competitive, they needed an end-to-end CI/CD solution that could streamline development, ensure quality, and enable rapid, reliable deployments across multiple environments.

Challenges Faced

Before the transformation, the client faced several pain points:

Manual Builds & Deployments

Developers and operations teams spent hours packaging, testing, and releasing updates by hand.

Long Release Cycles

Feature releases took weeks, with extensive manual QA and approvals introducing delays.

Inconsistent Environments

Differences between development, staging, and production often caused unexpected failures after deployment.

High Rollback Risk

Limited automation meant deployments were error-prone, increasing the risk of costly rollbacks.

Spundan's Solution

Spundan's DevOps team partnered with the client to design and implement a secure, scalable CI/CD pipeline tailored to their stack and compliance requirements.

Key solution elements included:

Automated Build Pipelines

We configured automated build jobs triggered by every code commit. Developers merged code more frequently, reducing merge conflicts and integration issues.

Integrated Automated Testing

Unit, integration, and regression tests were embedded into the pipeline to catch bugs early and prevent defective builds from progressing.

Infrastructure as Code (IaC)

We standardized and versioned all infrastructure using Terraform and Ansible, ensuring consistency across dev, staging, and production environments.

Containerization & Orchestration

Applications were containerized with Docker and orchestrated using Kubernetes for predictable, repeatable deployments.

Blue-Green & Canary Deployments

We implemented deployment strategies to roll out changes safely, minimizing downtime and allowing quick rollbacks when needed.

Monitoring & Rollback Automation

Integrated monitoring ensured that if deployments failed health checks, the pipeline could automatically roll back to a stable version.

Developer Enablement

Spundan trained in-house teams to manage and maintain the pipelines, fostering a DevOps-first culture of continuous improvement.

Implementation Timeline

The transformation was executed in three phases over eight months:

1

Discovery & Planning

Assessed existing workflows, tools, and compliance needs. Defined pipeline architecture and success metrics.

2

Pilot Projects

Built and tested pipelines for a core set of critical applications to validate automation and deployment strategies.

3

Full Rollout

Extended CI/CD pipelines to all services, integrated with code repositories, issue trackers, and cloud environments. Provided training and documentation to ensure smooth adoption.

Key Outcomes

“With Spundan's CI/CD framework, we've slashed our release cycle from two weeks to under two days. Our developers push updates with confidence, and our customers benefit from faster innovation.”
— VP of Engineering, FinTech Client

  80% reduction in release cycle time from bi-weekly deployments to daily releases.

  Near-zero downtime deployments using canary and blue-green strategies.

  Higher quality releases with automated testing catching bugs before production.

  Greater team productivity as developers spend less time on manual packaging and approvals.

Lessons Learned

Automation needs clear governance

Well-defined branching, testing, and approval workflows were critical to keep pipelines secure and compliant.

Small, frequent releases reduce risk

Smaller changes deployed more often meant faster rollback and recovery when issues occurred.

Culture shift matters

Early and continuous training ensured teams adopted DevOps best practices and owned the new processes.

Conclusion

By implementing CI/CD practices, the company transformed its delivery pipeline into a robust, automated system that supports rapid and reliable software releases. The CI/CD pipeline not only enhanced developer productivity but also improved overall software quality and customer satisfaction.

This case study illustrates how CI/CD acts as a foundational component of DevOps maturity, empowering teams to innovate quickly and deliver business value continuously.
