I am shifting from traditional systems administration into cloud engineering. For those who successfully made the transition, what cloud project helped you get hired at a top-tier tech company? Did you build a hybrid cloud architecture simulation, or does showcasing a legacy application migration project yield better callback rates from HR?

The project that secured my current role was a comprehensive lift-and-shift migration simulation of a legacy three-tier e-commerce application. I moved it from an on-premises architecture over to AWS using containerized microservices. I set up a robust CI/CD pipeline using Jenkins and Docker, deploying directly to AWS ECS. What really caught the engineering director's attention was my detailed documentation outlining how I minimized downtime during the database cutover using AWS DMS, along with a rollback strategy if things failed.
Were you able to include any live monitoring tools like Prometheus or Grafana in that container migration project to show how you tracked system health throughout the transition process?
An automated blue-green deployment architecture using AWS CodePipeline and Route 53 traffic routing got me three offers. It shows you understand zero-downtime production deployment needs.
Zero-downtime concepts are critical. Showing a blue-green deployment setup directly answers the core question regarding what portfolio pieces engineering directors are actively looking for.
Yes, I integrated Prometheus for metrics collection and Grafana for visual dashboards. Tracking metrics like CPU utilization and memory throttling during the live container migration process gave me concrete data points to present during the system design phase of my technical interviews.
