Elasticity refers to the automatic adjustment of cloud resources (such as compute power, memory, or storage) up or down based on demand, ensuring efficient resource utilization and cost control.
Multitenancy allows multiple customers to share the same cloud infrastructure securely.
Containers package applications and their dependencies, but they don't inherently adjust resources. Scalability refers to the ability to grow resources (manually or automatically), but elasticity specifically emphasizes dynamic, on-demand adjustment.
Elasticity best describes automatic resource adjustment in cloud environments.
