Cloud services have the following main features:

Flexible expansion: Cloud services can be flexibly expanded according to users' needs, and dynamically allocate and release computing resources according to actual usage. Users can increase or decrease computing power at any time according to business requirements, thus avoiding resource waste and excessive investment.

Resource sharing: Cloud services divide physical resources (such as servers and storage devices) into multiple virtual resources through virtualization technology, and multiple users can share the same set of physical resources. This resource sharing method improves the resource utilization rate and reduces the cost.

Pay-as-you-go: Cloud services usually adopt the pay-as-you-go model, and users only need to pay the actual amount of resources without purchasing expensive hardware equipment or software licenses in advance. This flexible payment mode enables small and medium-sized enterprises and individual users to enjoy high-end computing power.

Reliability and availability: Cloud service providers usually set up data centers in multiple geographical locations to ensure the reliability and availability of services through redundancy and backup mechanisms. Even if one data center fails, users' data and applications can continue to run in other data centers.

Cloud services provide users with flexible, reliable and efficient computing resources and services, which are widely used in IT infrastructure, development and testing environment, big data analysis, online applications and mobile applications.
