This cannot be achieved with legacy on-premise software.

Google have massive data centres filled with their own hardware that is efficient and cost effective. Google's infrastructure is designed from scratch to host a global Internet platform that is capable of scaling to millions of users while providing near constant up-time and frequent feature updates.

Google's multi-tenant infrastructure is designed so they can push improvements to their entire customer base very quickly. Google can deliver new functionality at rapid pace as systems are able to distribute updates so efficiently.

Browser-based applications are another key ingredient in our recipe for rapid innovation. When Google launch new features in our web applications, users automatically get these improvements just by refreshing their browsers. Google’s mobile browser applications also get new features without software updates.
