Cloud computing
Cloud computing refers to the delivery of computing services, including servers, storage, databases, networking, software, analytics, and intelligence, over the internet ("the cloud"). Rather than having to invest in and maintain physical hardware and infrastructure, users can access these services on-demand from a cloud service provider, paying only for what they use.
There are several types of cloud computing services, including:
1. Infrastructure as a Service (IaaS): provides access to virtualized computing resources such as servers, storage, and networking.
2. Platform as a Service (PaaS): provides a platform for developers to build, test, and deploy applications without having to manage the underlying infrastructure.
3. Software as a Service (SaaS): provides applications that are accessible via a web browser or API, eliminating the need for users to install and maintain software on their own computers.
Cloud computing offers many benefits, including increased scalability, flexibility, reliability, and cost-effectiveness. It has become an essential technology for businesses and organizations of all sizes, as well as individuals who use cloud-based services for personal use.
