The CTO Podcast with Fexingo · 2026-07-23 · 9 min
In this episode, Lucas and Luna dive into Wix's massive architectural overhaul of its website builder platform to support 200 million users. They explore the decision to migrate from a monolithic PHP system to a microservices-based architecture, the challenges of maintaining backward compatibility while introducing a new drag-and-drop editor, and how Wix managed to reduce page load times by 40 percent without disrupting existing sites. The discussion touches on the trade-offs between consistency and flexibility, the role of WebAssembly in client-side performance, and the engineering team's approach to incremental migration. A concrete look at how a consumer-facing platform scales its core product without breaking the user experience. #Wix #WebDevelopment #PlatformEngineering #Microservices #Migration #WebAssembly #Scalability #Performance #BusinessAndTechnology #BusinessPodcast #FexingoBusiness #CTOPodcast #TechnicalLeadership #Architecture #EngineeringOrg #SiteBuilder #CloudMigration #IncrementalMigration Keep every episode free: buymeacoffee.com/fexingo
