Hyperscaler Database vs Private Cloud Managed PostgreSQL
When your application needs a production PostgreSQL database, you face a fundamental choice: run it on a hyperscaler's managed service, operate it yourself, or delegate operations to a specialist. Each path has different implications for data sovereignty, vendor lock-in, and total cost.
This comparison covers five options available to Swiss organisations today.
Quick comparison

|---|---|---|---|---|---|
| Data location | EU (Frankfurt, Zurich) | EU (Zurich) | EU (various) | Your choice | Your choice (Swiss cloud or on-premises) |
| Jurisdiction | US (CLOUD Act) | US (CLOUD Act) | Finnish company, US infrastructure | Your jurisdiction | Swiss company, Swiss or your infrastructure |
| Data sovereignty | Limited — US parent company | Limited — US parent company | EU company but data on US hyperscalers | Full control | Full — Swiss operations, your infrastructure |
| Ops model | Fully managed by AWS | Fully managed by Google | Fully managed by Aiven | You manage everything | VSHN manages, you control infrastructure |
| SLA | 99.95% (Multi-AZ) | 99.95% (regional) | 99.99% (Premium) | None (your own) | Up to 99.99% |

| Vendor lock-in | High (AWS ecosystem) | High (GCP ecosystem) | Medium (multi-cloud, but proprietary layer) | None | None — runs on any infrastructure |
| Starting price | ~$170/month (db.t3.medium, Multi-AZ) | ~$130/month (db-custom, regional HA) | ~$200/month (Business plan) | $0 (software) + ops team | CHF 80/month (single), CHF 480/month (HA with SLA) |
AWS RDS for PostgreSQL
Amazon RDS is the market leader in managed PostgreSQL. It handles provisioning, patching, backups, and failover within the AWS ecosystem.
Strengths:
- Mature service with a broad feature set (read replicas, Performance Insights, automated backups)
- Zurich region (eu-central-2) available since 2022
- Deep integration with AWS services (Lambda, IAM, CloudWatch)
- Automated minor version upgrades
Limitations:
- US jurisdiction applies. Amazon is a US company subject to the CLOUD Act. Even with a Zurich region, US authorities can compel data access without Swiss judicial process.
- No Swiss cloud or on-premises option. AWS RDS runs exclusively on AWS infrastructure — no deployment on cloudscale.ch, Exoscale, or your own data centre.
- Deep AWS lock-in — IAM roles, VPC networking, and monitoring are AWS-specific
- No EDB enterprise tools or Oracle compatibility layer
- Pricing scales with compute, storage, IOPS, and backup separately — costs are hard to predict
Best for: Teams already committed to AWS who accept US jurisdiction trade-offs.

Google Cloud SQL for PostgreSQL
Cloud SQL is Google's managed relational database service. The Zurich region (europe-west6) puts compute and storage in Switzerland.
Strengths:
- Zurich region with low-latency access from Swiss infrastructure
- Automated backups, point-in-time recovery, and high availability
- Integration with Google Cloud IAM and VPC
- Competitive pricing for smaller instances
Limitations:
- Same US jurisdiction issue as AWS. Google is subject to the CLOUD Act regardless of data location.
- No Swiss cloud or on-premises option. Cloud SQL runs exclusively on Google infrastructure — no deployment on cloudscale.ch, Exoscale, or your own data centre.
- GCP lock-in — networking, identity, and monitoring are GCP-specific
- No Oracle compatibility or EDB tooling
- Major version upgrades require downtime or manual migration
- Maximum storage of 64 TiB but IOPS tied to disk size — performance tuning is constrained
Best for: Teams invested in Google Cloud who need a Zurich-hosted database.

Aiven for PostgreSQL
Aiven is a Finnish company offering managed databases across multiple clouds. They deploy PostgreSQL on AWS, GCP, or Azure infrastructure in your chosen region.
Strengths:
- EU-headquartered company (Helsinki)
- Multi-cloud — deploy on AWS, GCP, or Azure without changing provider
- Terraform provider for infrastructure-as-code workflows
- Good developer experience with CLI tools and integrations
Limitations:
- No Swiss-owned infrastructure option. Aiven runs on US hyperscalers even in EU regions, so CLOUD Act exposure remains.
- No dedicated Swiss region — closest is typically Frankfurt or Zurich on the underlying hyperscaler
- No Oracle compatibility or EDB partnership
- Premium tier required for 99.99% SLA
- Higher starting price than direct hyperscaler offerings
Best for: Multi-cloud teams wanting a single database provider across AWS, GCP, and Azure.
Self-Hosted PostgreSQL
Running PostgreSQL on your own VMs or Kubernetes clusters gives you complete control over every aspect of the database.
Strengths:
- Full control over data location, version, configuration, and access
- No per-service fees — only infrastructure costs
- Can run on any provider including Swiss clouds (cloudscale.ch, Exoscale)
- Full access to EDB tools if you hold your own EDB licence
Limitations:
- Operational burden is substantial. Production PostgreSQL requires:
- 24/7 monitoring and incident response
- Backup automation with regular restore testing
- Replication setup and failover testing
- Security patching (including emergency zero-day fixes)
- Major version upgrades with thorough testing
- Connection pooling, vacuum tuning, and performance management
- A PostgreSQL DBA in Switzerland costs CHF 130,000-160,000/year
- Smaller teams often defer upgrades and skip restore testing — both create risk that only surfaces during incidents
- Building HA with automated failover (Patroni, repmgr, or CloudNativePG) requires deep PostgreSQL and infrastructure expertise
Best for: Large organisations with a dedicated database team and specific customisation needs.
VSHN Managed PostgreSQL (EDB Partner)
VSHN operates your PostgreSQL instance on the infrastructure you choose — Swiss cloud or on-premises. As an official EDB partner, VSHN provides access to EDB enterprise tools including the Oracle compatibility layer.
Strengths:
- Swiss company, Swiss jurisdiction — VSHN is headquartered in Zurich. No CLOUD Act exposure through the operations layer.
- Your infrastructure, your choice — cloudscale.ch, Exoscale, or on-premises
- Official EDB partner — access to EDB Postgres Advanced Server, Oracle compatibility, and EDB migration tooling
- Automated backups with configurable schedule and retention (default: daily, 6 retained)
- CloudNativePG operator for Kubernetes-native high availability
- Up to 99.99% SLA with service credits
- ISO 27001 certified operations since 2014
- Self-service provisioning via Kubernetes API or Servala
Pricing:
| Plan | Single instance | Replicated (HA) |
|---|---|---|
| Best Effort | CHF 80/month | CHF 160/month (2 replicas) |
| Guaranteed Availability (99.99% SLA) | — | CHF 480/month (2 replicas) |
Computing resources (CPU, memory, storage) are billed separately by the infrastructure provider. Support is available via VSHN support plans.
Best for: Swiss organisations needing data sovereignty, Oracle migration support, or production PostgreSQL without building a dedicated database team.
The sovereignty question
For Swiss companies in regulated industries (banking, insurance, pharma, government), data jurisdiction is not just a preference — it is a compliance requirement. Here is how the options compare on sovereignty:
| Dimension | AWS RDS / Cloud SQL | Aiven | Self-Hosted | VSHN Managed |
|---|---|---|---|---|
| Operating company jurisdiction | US | Finland (EU) | Yours | Switzerland |
| Infrastructure jurisdiction | US (even in Zurich region) | US (hyperscaler) | Your choice | Your choice |
| CLOUD Act exposure | Yes | Yes (via hyperscaler) | Depends on provider | No (Swiss ops + Swiss cloud option) |
| FINMA-compatible | Requires additional controls | Requires additional controls | Depends on implementation | Yes, with Swiss cloud infrastructure |
Choosing VSHN with a Swiss cloud provider (cloudscale.ch or Exoscale) eliminates US jurisdiction exposure entirely — both the operations company and the infrastructure provider are Swiss.
For a detailed analysis, see our PostgreSQL sovereignty assessment.
When to choose VSHN
VSHN Managed PostgreSQL fits when:
- Your data must stay under Swiss jurisdiction (not just in a Swiss data centre owned by a US company)
- You are migrating from Oracle and need EDB enterprise tools and migration expertise
- You want PostgreSQL on your existing cloud tenant — managed by specialists, not your dev team
- Your team is too small for 24/7 database operations but too regulated for a US-owned SaaS
- You need predictable monthly costs instead of pay-per-IOPS pricing that surprises at invoice time
