Virtualisation

A virtual platform offers what physical servers never can: rolling back to the state before an update, moving a server to different hardware in minutes and using capacity properly instead of five boxes humming away at idle. We design, build and run the environment remotely, whether the host sits in your office, in a data centre or has been replaced by Azure altogether.

What the service covers

We build new platforms and take over existing ones, including moving physical servers onto them.

Talk it through with us

Sizing

Processors, memory and storage calculated from the machines that will run, with headroom for peaks and growth.

Platform choice

Hyper-V, VMware or Proxmox, chosen on licensing cost, skills and what you already own.

Migration

Physical servers converted into virtual machines with a short, agreed downtime window.

Resource limits

Quotas and priorities so one hungry machine cannot starve its neighbours.

Snapshots and backup

A firm rule of taking a snapshot before changes, while real data protection lives in a separate backup outside the host.

Redundancy

A second host that takes over on failure, or replication to a data centre or Azure.

How we deliver it

A small environment is up and running in one to two weeks. Servers are moved one at a time in agreed windows.

Assessment

Which servers exist, how busy they are, what should be moved and what is better retired.

Plan

Host specification, network, storage and migration calendar. You buy the hardware from your supplier, who also racks it or ships it to the data centre.

Build

Once the host has power and network, we take over through its out-of-band console (iDRAC, iLO or similar) and install everything from scratch.

Operations

Snapshots, backup, resource monitoring and a written plan for what happens if a host fails.

Virtualisation puts all your eggs in one basket, and you need to plan for that. When servers stood apart, one failure took down one service. Now a faulty host can stop everything at once. A second host, or at the very least fast recovery to spare hardware or the cloud, is no longer a luxury.

Common questions

Modern hypervisors add very little overhead, and it goes unnoticed in daily use. Trouble starts when a host carries more machines than it can handle. That is a sizing mistake, not a flaw in the technology.

Yes, that is how most run today, whether it is Business Central on-premises or a SQL Server behind your line-of-business application. What matters is enough resources, fast SSD storage and keeping the database off disks shared with write-heavy machines.

A snapshot sits on the same storage and is lost along with it. Forget about it for a month and it also slows the machine down. It is a tool for undoing an update, not a safety copy of your data.
