Cloud networks are systems that allow users to access and store data over the internet instead of on local computers. This technology enables individuals and businesses to use resources like servers, storage, and applications remotely, making it easier to collaborate and share information. Popular examples of cloud services include Google Drive, Amazon Web Services, and Microsoft Azure. These networks operate through a series of interconnected servers located in data centers around the world. By using cloud networks, users can scale their resources up or down as needed, ensuring flexibility and efficiency. This approach also enhances data security and backup options, as information is stored off-site.
