IaaS

IaaS stands for Infrastructure as a Service. It is a cloud computing service model that provides virtualized computing resources over the internet. IaaS providers allow customers to access and manage fundamental computing resources such as storage, servers, networking, and operating systems as needed, paying only for what they use.

In this model, the provider is responsible for managing the physical data center infrastructure, including hardware, networking equipment, and data center facilities. The customer can deploy and run their applications, databases, and other software on these virtualized resources without having to manage any physical infrastructure.

IaaS offers several benefits to customers, including flexibility, scalability, and cost-effectiveness. Customers can quickly provision resources as needed and pay only for what they use, avoiding the upfront costs of buying and maintaining physical infrastructure. They can also easily scale up or down their infrastructure based on changing business needs.

Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and Digital Ocean. These providers offer a range of infrastructure services, from basic virtual machines to advanced networking and storage options. Customers can choose the services that best meet their needs, and the provider takes care of the underlying infrastructure.
