Client Background
This established Taiwanese retail chain has embraced digital transformation with membership programs, mobile payments, e-coupons, and personalized notifications.
As user traffic grew, the legacy system—built for physical stores—struggled during promotions, affecting customer experience and raising costs. The company engaged a consulting team to modernize the architecture and migrate to the cloud for greater stability and flexibility.
Challenges
One of the legacy systems relied heavily on manual processes—code integration, deployment, and releases all required human effort.
While manageable in the past, this approach is inefficient in today’s fast-paced environment. Releasing new features consumes excessive time, is prone to errors, and, without automated testing, requires manual verification, adding pressure on the development team.
Our Solutions
We helped the client implement an automated CI/CD workflow, enabling faster and more reliable feature releases:
✅ Git-based Development: Transitioned the team to Git version control with Git Flow, reducing integration errors and improving collaboration.
✅ Environment Separation: Established distinct environments for development, testing, user acceptance, and production to prevent interference.
✅ AWS Automation: Built a CI/CD pipeline using CodePipeline, with CodeBuild for automated builds and CodeDeploy for blue-green deployments, enabling seamless updates.
✅ Standardized System Images: Used Packer to create consistent host configurations, minimizing “works on my machine” issues.
✅ Real-time Notifications: Integrated Slack and LINE for instant deployment updates to the team.
✅ Infrastructure as Code (IaC): Programmatically managed all environment settings for easier replication, modification, and reduced human error.
Implementation Results
After implementing the automated development and deployment workflow, the client achieved significant results:
🚀 Saved ~70% of monthly labor hours, with previously manual tasks now automated, reducing errors and accelerating development with higher quality.
🚀 Management gained clear visibility into feature progress and releases, improving team efficiency, workflow, and laying a solid foundation for future expansion.
