Cloud computing is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centers and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).
Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) are the leading cloud providers, offering a wide range of cloud services and global data center presence. IBM Cloud specializes in hybrid cloud solutions, while Oracle Cloud focuses on databases and enterprise services. The choice of cloud provider depends on specific needs, such as scalability, geographic presence, and budget constraints.
Who is using cloud computing?
Organizations of every type, size, and industry are using the cloud for a wide variety of use cases, such as data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications. For example, healthcare companies are using the cloud to develop more personalized treatments for patients. Financial services companies are using the cloud to power real-time fraud detection and prevention. And video game makers are using the cloud to deliver online games to millions of players around the world.
