Cloud computing eliminates the expense of setting up and running on-site datacenters, which often have added costs such as employing staff and buying and maintaining land, buildings, and computer hardware. The cloud allows businesses to access the computer resources they need in real time to match their business needs on demand.
More efficiently develop and manage your applications with nearly unlimited cloud computing resources. Cloud providers continuously update their datacenter networks with the latest-generation hardware, providing you with fast, efficient computing resources that never go obsolete and would be more costly to implement in a single datacenter.
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 datacenter 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 Azure, manages the infrastructure, while you purchase, install, configure, and manage your own software—operating systems, middleware, and applications.
