Zombie Servers
Definition
Systems that have no activity in the last six months are called comatose or zombies.
Numbers
25% of all physical servers and 30% of all virtual servers are comatose (Koomey & Anthesis, 2017).
Wasted costs: $26 billion (Business2Community.com)
Problems
- waste of money (tens of billions of dollars in the US alone)
- waste of energy
- security risk (zombie servers aren't patched and maintained)
