IaaS
Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet, such as virtual machines, storage, and networking. It allows users to rent infrastructure on-demand without managing physical hardware, offering scalability and flexibility. IaaS providers handle the underlying infrastructure, while users control the operating systems, applications, and data.
Developers should learn IaaS when building scalable applications, managing dynamic workloads, or reducing capital expenses on hardware. It is ideal for use cases like web hosting, development and testing environments, and disaster recovery, as it enables rapid provisioning and pay-as-you-go pricing. IaaS is particularly useful for startups and enterprises needing infrastructure agility without upfront investments.
