There are three main cloud computing service models that we will be covering in this chapter. These three models provide the basis for the services provided by cloud computing service providers.
Infrastructure as a Service (IaaS) is a cloud computing service model where a provider delivers virtualized IT infrastructure resources over the internet:
The organization manages:
- Server operating systems
- Data storage
- Applications deployed to servers, such as:
- Web-based enterprise applications
- Database servers
- Management agents, such as host intrusion prevention
The cloud computing service manages the underlying cloud infrastructure, which includes:
- Processing
- Physical storage
- Networks
