Infrastructure as a Service (IaaS) is the most basic category of cloud computing services. It aims to give you complete control over the hardware that runs your application. With IaaS, you rent IT infrastructure servers and virtual machines (VMs), storage, networks, and operating systems from a cloud provider on a pay-as-you-go basis. It’s an instant computing infrastructure, provisioned and managed over the internet.

Advantages:

No CapEx: Users have no upfront costs.
Agility: Applications can be made accessible quickly, and deprovisioned whenever needed.
Consumption-based model: Organizations pay only for what they use and operate under an OpEx model.
Skills: No deep technical skills are required to deploy, use, and gain the benefits of a public cloud. Organizations can leverage the skills and expertise of the cloud provider to ensure workloads are secure, safe, and highly available.
Cloud benefits: Organizations can leverage the skills and expertise of the cloud provider to ensure workloads are made secure and highly available.
Flexibility: IaaS is the most flexible cloud service as you have control to configure and manage the hardware running your application.

Disadvantages:

Management: The shared responsibility model applies; the user manages and maintains the services they have provisioned, and the cloud provider manages and maintains the cloud infrastructure.
