service models

Service models refer to frameworks that describe how services are delivered and managed. Common models include: 1. **Infrastructure as a Service (IaaS)**: Provides virtualized computing resources over the internet, allowing users to rent servers and storage. 2. **Platform as a Service (PaaS)**: Offers a platform for developers to build, deploy, and manage applications without worrying about underlying infrastructure. 3. **Software as a Service (SaaS)**: Delivers software applications over the internet on a subscription basis, eliminating the need for installation or maintenance on local devices. These models help businesses choose the right solutions for their needs.
