What is the term for delivering computing services online to improve scalability?

The term that refers to delivering computing services online to enhance scalability is cloud computing. This concept allows users to access a vast array of services, including storage, processing power, and applications, over the internet. The key advantage of cloud computing is its ability to scale resources up or down based on demand, enabling businesses to efficiently manage workloads without the need for physical infrastructure changes.

Cloud computing operates on a pay-as-you-go model, meaning organizations only pay for the resources they use, which also contributes to cost efficiency. This flexibility and scalability make it an essential solution for modern businesses seeking to adapt quickly to changing market conditions or varying workload demands.

In contrast, virtualization refers specifically to creating virtual versions of physical resources, while edge computing focuses on processing data closer to the source rather than relying on centralized data centers. Data hosting is a broader term referring to storing data on servers, which may not necessarily incorporate the expansive benefits of scalability and flexibility that cloud computing provides.
