Types of Cloud Computing

Service Models

Infrastructure as a service

  • Provides whole infrastructure of a computer as a service.
  • In this, we get complete access to the computer OS.
  • This eliminates the need for every organization to maintain the IT infrastructure.

Platform as a Service

  • This provides the development and deployment tools required to develop applications.
  • We need not have access to whole OS.

Software as a Service

  • This is a way of delivering applications/software over the Internet as a service.
  • Instead of installing and maintaining software, you can simply access it via the Internet. This frees you from complex software and hardware management.

Deployments Models

Public Cloud

  • This provides a shared platform that is accessible to the general public through an Internet connection.
  • If we have a valid billing agreement with CSP(Cloud Service Provider), then we can use their services.

Private Cloud

  • In this, the infrastructure is dedicated to a single organization.
  • This is also known as an internal cloud or corporate cloud.

Hybrid Cloud

  • A hybrid cloud is the combination of both public and private cloud deployment models. 

To illustrate the differences between public and private cloud deployment models, please see the diagram below:
