IaaS - Cloud Computing

What is Infrastructure as a Service (IaaS)?

Infrastructure as a Service (IaaS) is a way to rent storage, hardware, servers and network capacity over the Internet. The service provider owns massive computer resources and is responsible for running and maintaining them. Meanwhile, the client needs only computer and Internet connection to access these bottomless resources and typically pays for it on a per-use basis.

The main features and components of Iaas are:
  • service-oriented utility computing,
  • automation of administrative tasks,
  • unlimited resources,
  • on demand self-service,
  • pay-per-use pricing,
  • desktop virtualization,
  • policy-based services.
Infrastructure-as-a-Service (IaaS) is one of three models of cloud computing service. The other two are Software as a Service (SaaS) and Platform as a Service (PaaS).
