This document provides a reference architecture for a multi-tier application that runs on Compute Engine VMs in a single zone in Google Cloud. You can use this reference architecture to efficiently rehost (lift and shift) on-premises applications to the cloud with minimal changes to the applications. The document also describes the design factors that you should consider when you build a zonal architecture for your cloud applications. The intended audience for this document is cloud architects.
