Cloud computing encompasses a wide range of services, including storage (like Google Drive, Dropbox), processing power (like AWS EC2, Google Compute Engine), and software applications (like Microsoft 365, Salesforce) which are hosted on external servers and accessed via the internet. This model supports flexibility, scalability, and cost-efficiency, transforming how organizations manage their IT infrastructure and operations. Users can scale services up or down according to their needs, pay only for what they use, and access robust computing power without the upfront costs associated with owning physical hardware.
