What are the key characteristics of cloud computing?

The key characteristics of cloud computing are accurately outlined by the correct choice, which includes on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

On-demand self-service allows users to provision computing resources as needed automatically, without requiring human interaction with service providers. This characteristic is fundamental to cloud computing, as it provides immediate access to resources, allowing for greater agility and efficiency in managing applications and workloads.

Broad network access refers to the capability of cloud services to be accessed over the network using standard mechanisms, which enhances accessibility across various devices such as laptops, smartphones, and tablets. This characteristic supports the idea that users can work and access information from virtually anywhere.

Resource pooling is a critical aspect whereby multiple customers share the same physical resources, with the provider dynamically assigning and reallocating these resources according to customer demand. This not only optimizes the utilization of resources but also allows for cost efficiency and scalability, as resources are utilized when and where they are needed.

Rapid elasticity is the ability to quickly scale resources up or down based on the demands of the workload. This flexibility is essential for businesses as it enables them to respond to changes in demand efficiently without over-provisioning or under-utilizing resources.

Measured service indicates that cloud services
