Business Critical Applications

When an ERP, a customer database or an order system goes down, the work that depends on it stops too. On KASTERVO, you run these applications on compute instances inside your own KVPC, in a Digital Realty Tier 3 certified data center, and you configure the network and the firewall yourself.

Signs Your Infrastructure Is the Weak Point

Critical Apps on a Single Server

If an application still runs on one physical server, a failed disk or power supply takes it offline until the part is replaced. On KASTERVO, replacing failed hardware under your compute instances is our job, not yours.

Sensitive Data on a Flat Network

When a database shares a network segment with every workstation and test server, one compromised machine can reach it. In your KVPC, the database gets its own VLAN, and your firewall rules decide which systems can connect.

A Monthly Bill You Can't Forecast

Usage-based billing makes the cost of an always-on application hard to budget. Every KASTERVO unit has a fixed monthly price that doesn't depend on usage, and three-year plans keep the same rate for the whole term.

What Downtime on a Critical App Costs

An outage on a critical application stops orders, invoicing or production until it's back. The cost continues after recovery, as staff re-enter data and customers wait for delayed orders. Moving the application to KASTERVO takes your own server hardware and server room out of that risk. What runs inside your compute instances, including any redundancy the application needs, stays your design.

Where the Resilience Comes From

High-Availability Cluster

Your compute instances run on a multi-node, high-availability cluster, over an underlay encrypted end to end. You decide how each instance is sized and configured.

A Network You Isolate Yourself

Each KVPC is your own private network with an edge firewall you control. You choose VLAN IDs, define subnets and routing, and connect offices over IKEv2, OpenVPN, IPsec or WireGuard.

Compliance at the Infrastructure Layer

KASTERVO is PCI-DSS compliant as a Level 2 service provider, and customer data stays in the EU under GDPR. Our compliance covers the infrastructure we operate; your application, and how it handles cardholder or personal data, stays within your own compliance scope.

Building Blocks

Compute Sized per Resource

KASTERVO Compute Instances (KCI) are priced per GB of RAM, per CPU core and per GB of high-availability flash storage, so each server gets the resources its workload needs.
Backups With KEBS

KASTERVO Elastic Backup Service (KEBS) runs on Veeam, from an official Veeam Cloud & Service Provider partner. It's a separate, paid service.
Hosting for the Public Website

If the application has a public website, KASTERVO Premium Cloud Hosting (KPCH) offers yearly packages with Let's Encrypt SSL, unlimited traffic and an optional Cloudflare CDN.
Office Access Over Site-to-Site VPN

Your offices reach the application over a site-to-site VPN that enters your KVPC through the edge firewall.
