Infrastructure as a service (IaaS)

Infrastructure as a Service (IaaS) is a cloud computing model in which a third-party provider delivers infrastructure resources, such as virtual machines, storage, and networking, over the Internet. IaaS allows organizations to access and use these resources on a pay-as-you-go basis, rather than having to purchase, maintain, and manage the infrastructure themselves.

IaaS providers typically offer a range of virtualized resources that can be easily configured and scaled up or down based on an organization's needs. This allows organizations to quickly and easily deploy and manage their own applications and workloads without the upfront costs and ongoing maintenance of physical infrastructure.

IaaS providers often include additional services, such as security and backup, as part of their offerings. This makes IaaS an attractive option for organizations that want to focus on their core business, rather than on managing infrastructure.
