Infrastructure as a service (IaaS) is a cloud service delivery model that provides on-demand

infrastructure resources to organizations via the cloud, such as compute, storage, networking, and

virtualization4. IaaS is the most suitable cloud service delivery model for patching and updating cloud

resources properly, as it gives the cloud consumer compliance team more control and flexibility over

the operating system, middleware, virtual machines, and any apps or data5. IaaS also enables

automation and orchestration of the provisioning process, as well as scalability and reliability of the

infrastructure6.
