The client operated a fragmented ecosystem of 12 separate Drupal 7 websites across different regions, resulting in data silos, inconsistent branding, and massive maintenance overhead. Global API response times averaged 800ms, severely impacting their real-time logistics tracking operations. A hard deadline for Drupal 7 EOL was looming.
We architected a 'One Platform' strategy using a centralized Headless Drupal 10 content repository serving 12 localized React frontends via GraphQL. We implemented a multi-layer caching strategy using Varnish and Redis to offload traffic, and integrated ElasticSearch for sub-100ms tracking queries.
Achieving these results required a fundamental shift in infrastructure strategy. By moving away from monolithic dependencies and embracing a composable approach, we eliminated single points of failure.
