A cloud service is a technology that allows users to access and store data over the internet instead of on a local computer or server. This means that files, applications, and resources can be accessed from anywhere with an internet connection, making it convenient for both individuals and businesses. There are different types of cloud services, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These services provide various levels of control and management, enabling users to choose the best option for their needs while benefiting from scalability and cost-effectiveness.
