Infrastructure-as-a-Service (IaaS)

Infrastructure-as-a-Service (IaaS) refers to the internet-based provisioning of computing resources such as servers, networks, and data storage by a cloud service provider. The user handles operating systems, applications, and middleware, while the service provider handles networking, data storage, hard drives, and hardware. IaaS can pose unique data security challenges, such as cloud sprawl caused by multi-tenancy.
