Choosing a Managed PostgreSQL Provider for Production

Picking a managed PostgreSQL provider affects your data sovereignty, operational burden, disaster recovery posture, and total cost for years. This page compares six options available to Swiss organisations today: self-hosted, the three major hyperscalers, Aiven, and VSHN Managed PostgreSQL.

This comparison focuses on community PostgreSQL. If your project requires Oracle compatibility or EDB enterprise tools, see enterprisedb.ch.

Quick comparison

Self-Hosted PostgreSQL

Running PostgreSQL on your own VMs or Kubernetes cluster gives full control over configuration, location, and access.

Strengths: complete data sovereignty, no per-service fees, all extensions available, any PostgreSQL version.

Limitations: the operational burden is substantial. Production PostgreSQL requires 24/7 monitoring, backup automation with restore testing, HA setup (Patroni, repmgr, or CloudNativePG), security patching, and major version upgrade management. A PostgreSQL DBA in Switzerland costs CHF 130,000–160,000/year. Smaller teams frequently defer upgrades and skip restore testing. Both create risk that surfaces only during incidents.

Fits when: your organisation has a dedicated database team with PostgreSQL expertise and specific customisation requirements that no managed service can meet.

Amazon 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 broad features (read replicas, Performance Insights, point-in-time recovery), Zurich region (eu-central-2) available since 2022, deep integration with AWS services.

Limitations: 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. RDS runs exclusively on AWS infrastructure. There is no deployment on cloudscale.ch, Exoscale, or your own data centre. Deep AWS lock-in with IAM, VPC, and CloudWatch dependencies. Pricing for compute, storage, IOPS, and backups is billed separately, making costs hard to predict.

Fits when: your team is already committed to AWS and accepts 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 and point-in-time recovery, competitive pricing for smaller instances.

Limitations: Google is subject to the CLOUD Act regardless of data location. Cloud SQL runs exclusively on Google infrastructure. GCP lock-in with networking, identity, and monitoring. Major version upgrades require downtime or manual migration. IOPS are tied to disk size, constraining performance tuning options.

Fits when: your team is invested in Google Cloud and needs a Zurich-hosted database.

Azure Database for PostgreSQL

Azure Database is Microsoft's managed PostgreSQL offering, available as Flexible Server with zone-redundant high availability.

Strengths: zone-redundant HA with 99.99% SLA, EU regions available, automated backups and point-in-time recovery, integration with Azure IAM and networking.

Limitations: Microsoft is subject to the CLOUD Act. Maximum storage is 16 TiB, which is lower than competing services. PostgreSQL version 18 not yet supported. Azure lock-in for networking, monitoring, and access control. Operations team based primarily in the USA and India.

Fits when: your team is already in the Azure ecosystem and needs managed PostgreSQL.

Aiven for PostgreSQL

Aiven is a Finnish company offering managed databases across multiple clouds. They deploy PostgreSQL on AWS, GCP, or Azure in your chosen region.

Strengths: EU-headquartered company (Helsinki), multi-cloud deployment across AWS, GCP, and Azure, good developer experience with CLI tools and Terraform provider.

Limitations: Aiven runs on US hyperscalers even in EU regions. CLOUD Act exposure remains via the underlying infrastructure. No Swiss-owned infrastructure option. The 99.99% SLA requires the Premium tier at higher cost. No dedicated Swiss region; closest option is typically the Frankfurt or Zurich region of the underlying hyperscaler.

Fits when: you want a single managed database provider across multiple hyperscalers and EU headquarters matters more than Swiss hosting.

VSHN Managed PostgreSQL (AppCat)

VSHN operates PostgreSQL on your chosen infrastructure via AppCat, using the open-source CloudNativePG operator on Kubernetes.

Strengths:

• Swiss company, Swiss jurisdiction. VSHN is headquartered in Zurich. No CLOUD Act exposure through the operations layer.
• Infrastructure of your choice. cloudscale.ch, Exoscale, on-premises, or eight providers via Servala.
• Fully open source. CloudNativePG is a CNCF project with no proprietary service layer.
• PostgreSQL versions 13–18, including the latest release.
• Automated daily backups with six retained copies (configurable).
• Up to 99.99% SLA with service credits.
• ISO 27001 certified operations.
• Self-service provisioning via Kubernetes API or Servala.

Pricing:

Computing resources (CPU, memory, storage) are billed separately by the infrastructure provider.

Fits when: Swiss jurisdiction is required, you want predictable pricing, or your team cannot sustain 24/7 database operations.

Which option fits?

Choose self-hosted if you have dedicated DBA capacity and need full configuration control.

Choose Amazon RDS or Cloud SQL if you are already committed to that hyperscaler ecosystem and US jurisdiction is acceptable.

Choose Azure Database if your organisation is in the Azure ecosystem and 99.99% zone-redundant SLA is required at Microsoft's price point.

Choose Aiven if you need a single managed database provider across AWS, GCP, and Azure without moving to a specialist operator.

Choose VSHN Managed PostgreSQL if your data must stay under Swiss jurisdiction, you need predictable CHF pricing, or your team wants to stop running PostgreSQL operations.
