Cloud services are available over the network and can be accessed through standard mechanisms, promoting usability across a wide range of devices such as smartphones, tablets, laptops, and desktops. This ensures that users can work from virtually anywhere, enhancing flexibility and collaboration.

Resource pooling is a defining feature of cloud computing, allowing multiple customers to share resources dynamically. The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources assigned and reassigned according to demand. This approach optimizes resource utilization and can lead to cost efficiencies.

Rapid elasticity is a hallmark of cloud computing, providing the ability to scale resources up or down quickly and easily. This elasticity allows businesses to handle workload spikes without investing in additional infrastructure, ensuring they only pay for what they use.

Measured service offers transparency and efficiency. Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service. This means that usage can be monitored, controlled, and reported, providing full visibility into resource consumption which can lead to smarter resource management and cost savings.

These characteristics collectively define what makes cloud computing a transformative technology, offering businesses unprecedented flexibility, efficiency, and scalability.
