This document summarizes the migration of Lush's global e-commerce platform from an existing vendor to Google Cloud Platform (GCP) in just 22 days. It describes how Lush's engineering team architected, built, migrated, tested, and launched the new infrastructure, which included migrating 146 databases and 400+ compute instances across 17 e-commerce sites and mobile apps. The migration was completed successfully before the deadline and reduced hosting costs by 40% while future-proofing Lush's technology stack in line with their ethical approach. Next steps involve further modernizing the platform on GCP through containerization, serverless computing, and machine learning capabilities.
