Using Virtualized Systems to Improve Preparedness & Operation

Practice makes perfect. Lack of preparedness has all too often transformed straightforward operational challenges into major downtime events (e.g., the 2017 British Airways episode). One of the root causes of this shortcoming has perversely been high-uptime. If equipment and systems have few unscheduled outages, familiarity with corrective procedures frequently atrophies. The advent of VMs permits sites to create exercise versions of their production environments, which while a fraction of the power of the actual production environment can be used to exercise hardware and software faults with a high degree of fidelity at a fraction of the cost of a clone of the full production environment. Such environments are also both checkpointable and expendable, allowing practice to be done with low levels of risk.
