Thirty legacy apps outlive the hypervisor renewal

Every enterprise has the shelf: the 2011 expense tool, the badge-printing service, the reporting app whose vendor folded. Thirty of them, each on its own VM because nobody dares co-host them, on a hypervisor licensed per core at a renewal number that keeps climbing.

The shelf moves into thirty containers on one rented server. Each app gets its own filesystem, its own ports, its own daemon entry so it restarts on its own. They're isolated at the OS level, which was the only reason they sat on separate VMs. Twenty-eight handle a few requests a day; idle, they cost almost nothing, because clones share disk blocks and the kernel caches common binaries once.

The hypervisor renewal was declined. The host is maintained by the platform, and the per-core license had nothing left to count.
