IaaS (Infrastructure as a service)

What does Infrastructure as a Service (IaaS) mean?


Infrastructure as a Service (IaaS) also known as HaaS (Hardware as a service) is the process of delivering a complete compute stack as an abstract, virtualized construct, including servers, storage, networking, and operating software.

IaaS, like other service-based offerings (Software as a Service, Platform as a Service), enables users to consume only what they require while delegating complex and costly management tasks to their provider.

This type of technology is a branch of Web Hosting however is generally geared more towards large specialized applications which need to be scaled as they use more resources.

Using  IaaS cloud services can ensure your company has the ability to grow and change as needed with the options to downgrade or scale resources on-demand.
