The US National Institute of Standards and Technology (NIST) defines infrastructure as a service as: [3].

Gartner defines a hybrid cloud service as a cloud computing service that is composed of some combination of private, public and community cloud services, from different service providers.

OpenStack is a free, open standard cloud computing platform. It is mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. [2]
Service orientation provides significant advantages for IT infrastructure services. The main benefits include increased utilisation of individual resources (meaning lower total cost of ownership) and increased service-levels as applications do not depend on the availability of any individual resource, but may use any one resource available in the pool.
As a result, infrastructure resources can be increased rapidly, instead of waiting weeks for computers to ship and set up. IaaS requires time and expertise to make use of the infrastructure in the form of operating systems and applications. [4] Platform as a service (PaaS) includes the operating system and middleware, but not the applications.
Hard infrastructure is the physical networks necessary for the functioning of a modern industrial society or industry. [5] This includes roads, bridges, and railways.
