Elasticity
Elasticity is a fundamental concept in cloud computing and distributed systems that refers to the ability of a system to automatically scale resources up or down in response to changing demand. It enables applications to handle varying workloads efficiently by provisioning or deprovisioning compute, storage, or network resources dynamically. This ensures optimal performance and cost-effectiveness without manual intervention.
Developers should learn about elasticity to build scalable and resilient applications, especially in cloud environments where traffic can be unpredictable. It is crucial for handling peak loads (e.g., during sales events or viral content) while minimizing costs during low-usage periods, making it essential for modern web services, e-commerce platforms, and data-intensive applications. Understanding elasticity helps in designing systems that maintain performance and availability under varying conditions.
