VSHN AppCat Update – Major PostgreSQL Upgrades and More Control over Costs

Operating stateful services on Kubernetes has always been one of the more complex challenges – especially when it comes to databases like PostgreSQL.

With the latest VSHN AppCat release, we’re introducing a major milestone for our PostgreSQL offering based on CloudNativePG, along with improvements that give users more control over how their services are managed and operated.

This release focuses on three key areas: database lifecycle management, user control and cost optimization.

What is VSHN AppCat?

VSHN AppCat is the VSHN Application Catalog – a curated collection of production-ready applications that can be deployed and operated on Kubernetes with minimal effort.

Instead of manually installing and maintaining complex software stacks, AppCat allows teams to run services such as databases, identity providers or collaboration platforms as fully managed applications.

AppCat includes:

• Automated operations and lifecycle management
• Built-in monitoring, backup and maintenance
• Consistent deployments across Kubernetes environments

This enables teams to focus on their applications, while VSHN handles the operational complexity behind the scenes.

Major PostgreSQL Version Upgrades with CloudNativePG

This release introduces a significant new capability for PostgreSQL in AppCat: major version upgrades using CloudNativePG.

For the first time, users can upgrade the major version of their PostgreSQL instances within the AppCat environment.

Major version upgrades are one of the more sensitive operations in database lifecycle management. Making this available as part of a managed service is an important step in enabling long-term, sustainable operations of PostgreSQL workloads on Kubernetes.

PostgreSQL User Management for CloudNativePG

We’ve also introduced user management capabilities for PostgreSQL in our CloudNativePG-based offering.

While PostgreSQL itself has always supported user management, this functionality is now available and integrated within the AppCat-managed CloudNativePG setup.

This gives users more direct control over database access and roles within their managed PostgreSQL instances.

Bring Your Own Bucket for Backups

Another important addition in this release is the “Bring Your Own Bucket” feature.

Users can now specify their own unmanaged object storage bucket for backups instead of relying on automatically provisioned storage.

If a bucket is provided, AppCat will use the supplied credentials and skip internal bucket provisioning entirely.

This can be particularly useful for organizations that:

• Already operate their own storage infrastructure
• Want to consolidate storage across services
• Are looking for ways to optimize backup-related costs

Continuous Platform Evolution

Operating databases and stateful services on Kubernetes is continuously evolving – and this release represents an important step forward.

With major version upgrades, integrated user management, and more control over backup infrastructure, AppCat continues to expand the capabilities of managed services on Kubernetes.

As always, the goal remains the same: making complex operations simpler, safer and more predictable for teams running production workloads.
