Thus, the result of cloud elasticity is savings in infrastructure costs, in human capital, and in overall IT costs. An organization that normally runs certain processes on-premises can ‘cloudburst’ to take advantage of Cloud Elasticity and meet that demand, returning to on-premises operations only when the demand has passed. This approach brings real-time cloud expenditures more closely in alignment with the actual consumption of cloud services, for example when virtual machines (VMs) are spun up or down as demand for a particular application or service varies over time.Ĭloud Elasticity provides businesses and IT organizations the ability to meet any unexpected jump in demand, without the need to maintain standby equipment to handle that demand. This eliminates the need for IT administration staff to monitor resources to determine if additional CPU, memory, or storage resources are needed, or whether excess capacity can be decommissioned.Ĭloud Elasticity is often associated with horizontal scaling (scale-out) architecture, and it generally associated with public cloud provider resources that are billed on a pay-as-you-go basis. Monitoring tools offered by the cloud provider dynamically adjust the resources allocated to an organization without impacting existing cloud-based operations.Ī cloud provider is said to have more or less elasticity depending on the degree to which it is able to adapt to workload changes by provisioning or deprovisioning resources autonomously to match demand as closely as possible. Cloud Elasticity can be automatic, without need to perform capacity planning in advance of the occasion, or it can be a manual process where the organization is notified they are running low on resources and can then decide to add or reduce capacity when needed. Cloud Elasticity is the property of a cloud to grow or shrink capacity for CPU, memory, and storage resources to adapt to the changing demands of an organization.
