Infrastructure As A Service (IaaS)
Infrastructure As A Service
Infrastructure as a service (IaaS) is an instant computing infrastructure, provisioned and managed over the internet. It’s one of the four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS), and serverless.
IaaS quickly scales up and down with demand, letting you pay only for what you use. It helps you avoid the expense and complexity of buying and managing your own physical servers and other data center infrastructure.
Each resource is offered as a separate service component, and you only need to rent a particular one for as long as you need it. A cloud computing service provider, such as AWS, Azure, Google Cloud, manages the infrastructure, while you purchase, install, configure, and manage your own software—operating systems, middleware, and applications.
