Services can be scaled on-demand by the user. According to the Internet Engineering Task Force (IETF), such infrastructure is the most basic cloud-service model. IaaS can be hosted in a public cloud (where users share hardware, storage, and network devices), a private cloud (users do not share resources), or a hybrid cloud (combination of both).
OpenNebula is an open source cloud computing platform for managing heterogeneous data center, public cloud and edge computing infrastructure resources. OpenNebula manages on-premises and remote virtual infrastructure to build private, public, or hybrid implementations of infrastructure as a service (IaaS) and multi-tenant Kubernetes deployments.
As the OpenStack project has matured, vendors have pioneered multiple ways for customers to deploy OpenStack: OpenStack-based Public Cloud A vendor provides a public cloud computing system based on the OpenStack project. On-premises distribution In this model, a customer downloads and installs an OpenStack distribution in their internal network.
The following is a comparison of cloud-computing software and providers. IaaS (Infrastructure as a service) ... PaaS providers which can run on IaaS providers ...
According to The NIST Definition of Cloud Computing, [3] there are three service models associated with cloud computing: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). The concept of ITaaS as an operating model is not limited to or dependent on cloud computing.
The focus was on Infrastructure-as-a-Service (IaaS) based offerings but the interface can be extended to support Platform and Software as a Service offerings [3] as well. IaaS is one of three primary segments of the cloud computing industry in which compute, storage and network resources are provided as services.

"A cloud deployment model represents the way in which cloud computing can be organized based on the control and sharing of physical or virtual resources." [3] Cloud deployment models define the fundamental patterns of interaction between cloud customers and cloud providers. They do not detail implementation specifics or the configuration of ...
