What is IaaS?

Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet. This model allows users to rent IT infrastructures, such as servers and storage, from a cloud service provider on a pay-as-you-go basis, rather than investing heavily in physical hardware that they need to manage and maintain.

One of the key advantages of IaaS is its scalability and flexibility. Organizations can quickly scale their infrastructure up or down based on their needs without the constraints of physical hardware. In addition, IaaS gives users the ability to control and manage operating systems, applications, and middleware directly, while the provider takes care of physical maintenance and availability.

Understanding IaaS is critical in the context of modern IT infrastructure because it enables businesses to reduce costs, increase efficiency, and focus more on their core operations rather than on maintaining physical infrastructure. This service is an essential part of many companies' cloud strategies, particularly for managing workloads that require high availability and performance.
