Cloud computing is a broad term for anything that involves hosting services and delivering them over the internet.
Cloud computing delivers computing services like servers, storage, databases, networking, software, analytics, and intelligence over the Internet (the “cloud”). Cloud computing enables faster innovation, more flexible resources, and greater economies of scale than traditional, on-premise, or data center-hosted solutions. In simple terms, cloud computing is when a computer system’s resources, like data storage (called “cloud storage”) and computing power, are available whenever the user needs them via the Internet, without the user having to manage them directly.
An example is Dropbox, a system for storing and sharing files. Rackspace offers data, security, and infrastructure services. Salesforce is a cloud-based software company offering Software as a Service (SaaS) focused on sales, customer service, marketing automation, analytics, and application development. Azure, AWS, and Google Cloud are the most well-known hyperscale cloud service providers (CSPs) offering suites of cloud computing services, such as hosting, backup, and disaster recovery services.
