Cloud computing
  • 1. Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet to offer faster innovation, flexible resources, and economies of scale. Typically, users access cloud services through a web browser or a light-weight desktop or mobile app while the backend infrastructure is managed by a third-party cloud service provider. Cloud computing allows organizations to avoid upfront infrastructure costs and focus on projects that differentiate their businesses instead of on infrastructure. Moreover, organizations can scale up or down based on their requirements, pay only for what they use, and benefit from the latest technologies without having to invest in new hardware or software.
