Answer: Cloud computing
Explanation: Cloud computing is a computer and networking model in which client software, data, and computing resources are hosted remotely, so client computers and servers don't need to support as many on-site resources. In cloud computing, resources are provided as a service over the Internet. Cloud computing allows businesses to access shared computing resources quickly and efficiently, without having to invest in the physical infrastructure themselves. With cloud computing, businesses can scale resources up or down quickly and easily, depending on their needs. This makes it easier for businesses to remain agile, as they can quickly access additional computing power or storage when needed and easily adjust resources when necessary.
