Linux on KASTERVO

Linux servers on aging hardware, or on a platform that keeps the network out of reach, leave your team working around limits it didn't choose. On KASTERVO, your Linux workloads run on compute instances inside your own KVPC, with an edge firewall, VLANs and subnets you configure, in a Digital Realty Tier 3 certified data center.

Where Linux Hosting Holds You Back

Capacity Bought Up Front

Physical servers are bought for the peak you expect years ahead, and the spare capacity sits idle until then. Compute instances are priced per GB of RAM, per CPU core and per GB of flash storage, so you order each one at the size its workload needs.

Servers Exposed Directly to the Internet

A Linux server with a public IP and only a host firewall is one misconfiguration away from exposure. In your KVPC, internet traffic passes the edge firewall first, and you decide which ports reach which instances.

Network Features Behind a Higher Tier

Some platforms keep private networking, VPN or custom firewall rules for higher pricing tiers. Every KVPC includes VLANs, firewall rules and VPN connections over IKEv2, OpenVPN, IPsec or WireGuard.

What Changes When Linux Moves to KASTERVO

Moving Linux servers to compute instances takes hardware purchases and replacements for those servers out of your budget, and puts a fixed monthly price per unit in their place, one that doesn't move with usage. Your team keeps control of the operating system and everything installed on it. The network around the servers moves from a rack to the KVPC, where you configure it yourself.

How Linux Runs on KASTERVO

High-Availability Cluster

Your instances run on a multi-node, high-availability cluster, over an underlay encrypted end to end. Redundancy inside your services, such as a second web node or database replication, is yours to design across instances.

Backups With KEBS

Backups aren't included with compute instances. KASTERVO Elastic Backup Service (KEBS) adds them as a paid service, built on Veeam.

Building Blocks

Site-to-Site VPN

Connect your office or existing data center to the KVPC over a site-to-site VPN, so servers on both sides reach each other privately.
Databases and Web Applications

Run MySQL, PostgreSQL, web servers or application runtimes on compute instances backed by high-availability flash storage.
KPCH for Simple Websites

If all you need is a website and its database, KASTERVO Premium Cloud Hosting (KPCH) offers yearly packages with Let's Encrypt SSL and unlimited traffic, instead of a server you administer yourself.
Plan Lengths

Choose a three-year plan, whose rate stays the same for the whole term, a 1-year plan, or Pay-As-You-Go.
