Google Cloud has operated a region in Zurich since March 2019 — the europe-west6 region with three Availability Zones. As one of the first hyperscaler regions in Switzerland, it is particularly mature and offers a broad spectrum of services. In this guide, we show how to host your Replit app compliantly with Google Cloud Switzerland.
Why Google Cloud Zurich?
The Google Cloud Zurich region was one of the first major cloud regions in Switzerland and offers a comprehensive service portfolio:
- 3 Availability Zones: europe-west6-a, europe-west6-b, europe-west6-c
- Broad service portfolio: Compute, Storage, Databases, AI, Analytics
- Direct Interconnect: Private network connectivity to Swiss locations
- Compliance: ISO 27001, SOC 1/2/3, PCI DSS, FINMA-compliant
- Active since 2019: Proven and stable with years of operational experience
Swiss Data Protection: Why Local Hosting Matters
nDSG Requirements
The new Swiss Data Protection Act (nDSG) sets clear requirements:
- Transparency Obligation: Users must know where their data is processed
- Data Transfer Rules: Transfers abroad only under specific conditions
- Privacy by Design: Data protection must be planned from the start
- Breach Notification: Rapid reporting to the FDPIC in case of security incidents
