IaaS The provision of virtualized hardware, in most cases as virtual computing instances, is termed IaaS. The particular feature of this form of cloud service is the ability to change these instances on demand and at any time. This includes spawning new computing instances, altering existing ones by resizing or reassigning resources or shutting down unneeded instances dynamically. Basic working units for IaaS are virtual images, that are instantiated and deployed in the cloud and executed within virtual machines. They contain an operating system and additional software implementing the application. Due to complete virtualization, the physical infrastructure of the data centers of IaaS providers is totally transparent to their customers.
