Cloud computing operations model
Elastic, scalable, agile, fault-tolerant, highly available, and disaster recovery are all terminology associated with cloud computing, adding value, and benefiting an organization's operational model.
These inherent and defining characteristics allow a workload deployed into a cloud computing environment to become highly available and scale in and out (both vertically and horizontally), which maps closely to demand. This ability to be elastic in nature allows the agility to provide a highly effective operations and economics model to flex with the changing demands of a business.
By optimizing running hours and right-sizing resources in line with demand and changing requirements, the switch to an OpEx system of paying as you use things (also known as a consumption-based system) allows controlled and monitored spending of computing resources without the overcommit of a traditional CapEx computing cost model of deploying hardware in on-premises...
