With only one server, is virtualisation worth it?
Yes, in most cases, because virtualisation shortens recovery. A VM restarts on other hardware in hours; a bare-metal installation can take days and depends on finding an identical part. If two days of downtime are unacceptable for the company, virtualisation pays for itself at the first serious failure.
What happens to Windows Server 2016 after 12 January 2027?
It keeps working, but stops receiving security patches. Every vulnerability discovered from then on stays exploitable indefinitely, raising the risk for the whole network. Extended Security Updates via Azure Arc are paid and time-limited: they help you plan the exit calmly, not avoid it.
Should we swap VMware for Hyper-V or Proxmox?
It depends on scale and on who runs the platform. Up to two or three hosts with common workloads, Hyper-V does the job and is already paid for in the Windows Server licence. Proxmox is stable, but only pays off with people who know how to run it. In larger environments or with specific dependencies, keeping VMware remains a valid option.
Cloud or on-premises server: which is cheaper?
For most companies, the cheapest answer is a mix of both, decided workload by workload. Email and office documents win in the cloud. An ERP with a hardware-bound licence or tens of terabytes of project files wins on premises, on cost and on speed. The assessment compares the options over five years before any decision.
How long does it take to migrate a server?
As a rule, one week of assessment, two to four of preparation and testing and one weekend for cut-over. Migration runs in a scheduled window with a rollback plan ready, and every application is tested before the old machine is switched off. Delays come from old applications with no installer, licence or support, not from the technology.
What if the server fails at three in the morning?
There is almost always a warning: disks and RAID controllers alert days in advance, and monitoring picks it up. If it fails without warning, the backup takes over: with VMs and tested copies, the server comes back on other hardware the same day. 24/7 monitoring and night, weekend and public holiday intervention exist only in the Premium 365 plan.
