Open-Source Databases

A production database needs room to grow and a network you can lock down. On KASTERVO, you run MySQL, PostgreSQL and other open-source databases on compute instances inside your own KVPC. You administer the database; we operate the infrastructure underneath it.

Common Bottlenecks in Open-Source Database Deployment

Hardware Limits

As data grows, a database on fixed hardware runs short of memory and disk, and the next step up is a new server.

Exposed Database Ports

A database listening on a public IP is open to every scanner on the internet. The safer layout keeps it on a private segment that only your application servers can reach.

Who Runs What

On KASTERVO, the database is yours, from its configuration to its upgrades. We operate the hardware, the high-availability cluster and the platform. The compute instances your database runs on have a fixed monthly price per unit, whatever the query load.

Infrastructure for Your Database

High-Availability Cluster

Database servers run as compute instances on a multi-node high-availability cluster in a Digital Realty Tier 3 certified data center. Replication between database nodes, if you need it, stays part of your own design.

Isolation in KVPC

Put database instances on their own VLAN or isolated subnet, and decide with firewall rules which servers can connect.

Flash Storage by the GB

Storage is high-availability flash, billed per GB alongside RAM per GB and CPU per core.

In Practice

MySQL, PostgreSQL and More

Install the engine and version you need on a Linux compute instance.
VPN Access for Administrators

Reach database servers through VPN connections you manage, over IKEv2, OpenVPN, IPsec or WireGuard, instead of opening database ports to the internet.
Backups with KEBS

Back up your database servers with KEBS, built on Veeam and billed separately from your compute instances.
EU Data Residency and PCI-DSS

Database contents stay in the EU under GDPR, on infrastructure that's PCI-DSS compliant at service provider Level 2.
