Storage and Processing Delivered From the Cloud
Infrastructure as a service (IaaS) means delivering a virtual server, desktop computer or remote storage from the cloud. In other words, a hosting provider like Dell gives you a remote data center — where it manages the infrastructure, servers and virtualization — and you access your virtual computers and storage from the Internet through a secure virtual private network (VPN) connection.
An IaaS approach to infrastructure can offer:
Faster responses to changing business conditions or internal customer needs, enabled by rapid system provisioning and rapid scalability, both up and down, without the long-term lock-in of hardware purchases
Productivity increases resulting from access to your applications and data from anywhere and the reliability that comes from a distributed computing model
Reduced capital outlay for hardware acquisition, maintenance, data center real estate, and power and cooling, when using a pay-for-use (public cloud) model
