Cloud computing offers three main service models:
- IaaS (Infrastructure as a Service): Provides access to fundamental computing resources – virtual machines, storage, networks. Users manage the operating system, middleware, and applications. Example: Amazon Web Services (AWS) EC2, Microsoft Azure Virtual Machines.
- PaaS (Platform as a Service): Provides a platform for developing, running, and managing applications without the complexity of managing the underlying infrastructure. Users focus on application development. Example: Google App Engine, Heroku.
- SaaS (Software as a Service): Provides ready-to-use software applications over the internet. Users access the software through a web browser or app. Example: Salesforce, Microsoft Office 365, Google Workspace.
IaaS is like renting the raw materials to build a house. PaaS is like renting a plot of land with basic utilities already installed. SaaS is like renting a fully furnished house.
