Cloud Computing is a service where we use or rent computer systems or resources from a service provider to use for various tasks. In this process, there is no need for us to invest in purchasing hardware and software for the entire system. There's also no need to set up our own network infrastructure, reducing the responsibility for system maintenance (as the service provider takes care of it). Furthermore, upgrading the system is easier. Everyone can access the system and data over the internet, manage system resources through the network, and share resources (shared services).

Payment for renting the system can be done based on our needs — you pay only for what you use. If your requirements increase, you can easily purchase additional resources to enhance the capabilities of the Cloud Computing system without the need to upgrade the entire system and computer equipment. Therefore, small and medium-sized businesses, as well as educational institutions, have turned to Cloud Computing services, which not only reduce costs but also simplify operations significantly. It's akin to outsourcing this aspect of the business to focus more on the core tasks.
