Cloud Computing is the delivery of computing services including servers, storage, databases, networking, software, analytics, and intelligence over the Internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale.

Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. Users can rent virtual machines, storage, and networks on-demand. Examples include Amazon EC2, Google Compute Engine, and Microsoft Azure VMs.

Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with the infrastructure. Examples include Heroku, Google App Engine, and AWS Elastic Beanstalk.

Software as a Service (SaaS) delivers software applications over the internet on a subscription basis. Users access software through web browsers without installation. Examples include Gmail, Salesforce, and Microsoft 365.

Serverless Computing allows developers to build and run applications without managing servers. The cloud provider automatically handles the infrastructure, scaling, and server management. AWS Lambda and Azure Functions are popular serverless platforms.
