What is Cloud technologie?

Cloud technologies enable on-demand access to computing resources—servers, storage, databases, networking, software, analytics, and intelligence—over the internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale. Users typically pay only for the cloud services they use, helping lower operating costs, run infrastructure more efficiently, and scale as their business needs change. Common use cases include data storage, backup and recovery, software applications (SaaS), platform as a service (PaaS), infrastructure as a service (IaaS), testing and development, and big data analytics.
