Cloud services are on-demand computing resources—like storage, software, processing power, and databases—delivered over the internet instead of running on your own physical computer or servers.

Platform as a Service (PaaS)

• You get an environment to develop, test, and deploy apps without managing the underlying infrastructure.

• Example: Google App Engine, Heroku.

Software as a Service (SaaS)

• You access software through a web browser—no installation needed.

• Example: Gmail, Dropbox, Zoom, Microsoft 365.

Infrastructure as a Service (IaaS)

• You rent virtual servers, storage, and networks.

• Example: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform.
