Rapid elasticity is one of the five essential characteristics of cloud computing defined by industry standards and implemented in platforms like Microsoft Azure. It refers to the capability of a cloud environment to automatically and dynamically provision and de-provision computing resources in response to changing demand.
In this scenario, the retail application experiences massive spikes in traffic during a seasonal flash sale and needs to adjust capacity dynamically:
Unlike traditional on-premises environments where hardware must be overprovisioned for peak loads, rapid elasticity provides an elastic cloud infrastructure that expands and contracts seamlessly with demand.
