The Challenge
A vacation rental platform suffered weekly full-system outages, deployed once a week after days of QA coordination, and ran maintenance windows starting at 10 PM with engineers manually cycling servers through the night. The PHP 5.6 codebase on custom AMIs imposed a hard capacity limit of 20,000 properties.
Our Solution
We migrated simultaneously to PHP 7 and containerized infrastructure (Docker Swarm + Traefik), tripling capacity and enabling continuous deployment across teams on three continents.
The Results
SEV-1 outages dropped from 50+/year to fewer than 4 (95% reduction). Capacity tripled to 60,000+ properties. Deployments went from weekly to continuous. Maintenance moved from 10 PM to 3 PM.
