Infrastructure as a Service (IaaS) is a cloud computing model that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis. Unlike traditional infrastructure, where organizations have to purchase and manage physical servers and datacenter equipment, IaaS resources are hosted and maintained by a third-party service provider. Organizations can provision and use these resources as needed, making them flexible and efficient. IaaS offerings typically include virtual machines, containers, load balancers, firewalls, storage, and more. This model is widely used for various scenarios, including lift-and-shift migration, test and development, storage, backup and recovery, and web hosting. It offers benefits such as reduced capital expenditures, optimized costs, easy scalability, and enhanced security.
