Client Overview

An enterprise-tier ($75M ARR) payment processing company based in the USA, providing critical infrastructure for online merchants. They were facing significant challenges with deployment speed and reliability, which posed a direct threat to their SLAs and customer trust. Their existing manual processes were slow, error-prone, and created major hurdles for passing PCI DSS audits.

D2C Fashion Website Performance Problem

Problem

The client's engineering team was spending over 30% of their time on manual deployments and operational firefighting. This slowed down feature delivery to a crawl and introduced significant human error, leading to production incidents that violated their customer SLAs.

Key Challenges

Zero Downtime Migration Challenge

Slow, Risky Deployments

Releases were a multi-day, all-hands-on-deck affair, with a rollback rate of nearly 15%.

Fast Page Load Speed Challenge

Compliance Hurdles

Lacked the automation and audit trails necessary to easily prove PCI DSS compliance.

Unique UX Challenge

Scalability Concerns

The monolithic infrastructure could not handle peak transaction volumes, leading to outages.

High Traffic Handling Challenge

Security Vulnerabilities

Security scans were run infrequently and late in the process, leading to costly fixes.

Our Headless Shopify Plus Solution

Our Solution

Developers.dev deployed a dedicated DevSecOps Automation POD to design and implement a modern, secure, and automated software delivery platform on AWS.

🏗️ IaC Foundation

We codified their entire AWS infrastructure using Terraform, creating a version-controlled, auditable, and reproducible environment.

⚙️ Automated CI/CD Pipeline

We built a robust CI/CD pipeline using GitLab CI that automated building, unit testing, and containerization for their applications.

🔒 Integrated Security (DevSecOps)

We embedded Snyk for dependency scanning and SonarQube for static code analysis directly into the pipeline, failing any build that didn't meet security standards.

🐳 Containerization & Orchestration

We migrated their applications from EC2 instances to a managed Amazon EKS (Kubernetes) cluster, enabling auto-scaling and self-healing.

Implementation and Execution

API-First Design

Phased Rollout

Developed a phased roadmap, starting with the most critical payment service.

Cloud-Native on AWS

Driver Onboarding

Provided extensive training and documentation to the client's team to ensure a smooth handover and long-term success.

Third-Party Integrations

Data Migration

Conducted a 2-week deep-dive assessment to map out the existing architecture and pain points.

DevOps & CI/CD

Cloud Infrastructure

Implemented the Terraform code in a separate, secure repository with mandatory pull request reviews.

Agile POD Engagement

Continuous Iteration

Built the CI/CD pipeline with distinct stages for security scanning, testing, and phased deployments (dev, staging, prod).

Performance Engineering

Advanced Analytics

Established a shared Slack channel and daily stand-ups for seamless collaboration.

Positive Outcome

🚀 Deployment Frequency Increased by 1200%

From once every two weeks to multiple deployments per day.

✅ Change Failure Rate Reduced to <2%

Automated testing and validation caught issues before they reached production.

⬆️ Achieved 99.99% Uptime

The EKS cluster provided the resilience and scalability needed to handle peak loads without issue.

📜 Simplified Compliance

The immutable infrastructure and detailed audit logs from the pipeline made PCI DSS audits straightforward.
