PERF 8. How do you ensure that the capacity and throughput of your storage solutions matches demand?
The amount of demand placed on a system often varies over different cycles: product lifecycle, such as launch or growth; temporal cycles such a time of day, day of the week, or month; unpredictable cycles such social media visibility; and predictable cycles such as television episodes. Insufficient storage capacity or throughput to your workload can degrade user experience and, at worst, lead to system failure.
Best practices:
 Reactive Manage manually based on metrics.
 Planned Plan future capacity and throughput based on metrics and/or planned events.
 Automated Automate against metrics.
