Definition:
Cloud service models are different types of services provided through the cloud. They show which types of services are available to users through the cloud. Each model is for different needs and purposes. Each model provides a different level of control and management.
There are different types of Cloud Services that you can use to control the behavior of cloud systems.
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is a cloud service model that provides basic computing resources through the internet. These resources can include virtual servers, storage space, and networking services. Users can use these resources without buying and managing physical hardware.
For example, Amazon EC2 and Google Compute Engine are IaaS services. The cloud provider manages the physical infrastructure, while users manage their own applications and data.
Platform as a Service (PaaS)
Platform as a Service (PaaS) is a cloud service model that provides an environment for creating, running, and managing applications. Users can create and deploy applications without managing servers and other hardware resources.
For example, Google App Engine and Heroku are PaaS services. The cloud provider manages the infrastructure and platform, while users focus on developing applications.
Software as a Service (SaaS)
Software as a Service (SaaS) is a cloud service model that lets users use software through the internet. Users can use the software online without installing it.
Services such as Gmail, Google Docs, and Microsoft 365 are SaaS services. The cloud provider manages everything, and users only use the software.
