"Cloud scalability" refers to the ability of cloud-based infrastructure to automatically adjust resources in response to changing demands. This feature allows organizations to scale their computing power, storage, and other services seamlessly without significant upfront investments in physical hardware. As demand fluctuates, cloud scalability ensures optimal performance and cost-efficiency. It supports businesses in managing sudden increases in traffic or data without downtime, aiding in operational flexibility. This characteristic is vital for companies aiming to grow and adapt quickly in today's fast-paced digital environment.
