- SaaS. Software-as-a-service products provide a complete, turnkey application—including complex programs such as those for CRM or enterprise-resource management—via the Internet.
- PaaS. Platform-as-a-service products offer a full or partial development environment that users can access and utilize online, even in collaboration with others.
- IaaS. Infrastructure-as-a-service products deliver a full computer infrastructure via the Internet.
- DaaS. Desktop-as-a-service which utilize virtualization of desktop systems serving thin clients.
