Infrastructure as a Service (IaaS) is growing faster than any other segment of the cloud services market — outpacing both SaaS and PaaS, and Gartner predicts that growth will continue for at least the next 5 years. By 2020, worldwide IaaS revenue is expected to exceed $72 billion.

Defining IaaS
Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources over the internet.
In the IaaS model, cloud providers host the infrastructure components traditionally residing in an on-premises data center, including servers, storage, and networking hardware, as well as the virtualization layer, allowing users to scale quickly to meet demand.
Benefits of IaaS

Time-saving and cost efficient
Avoid the time and cost of buying, managing, and supporting in-house infrastructure, while offering uninterrupted access to data and the most advanced applications and technology
Purchase IaaS based on usage, with scalability based on growth, downsizing or seasonal changes
Dramatically improve service levels for end-users, as there are no wait times for hardware, components or on-site support, and critical infrastructure is left in the hands of experts

Enhanced protection and reliability
With IaaS providers having the tightest security measures in place, ensure end-users’ infrastructures and data are protected against potential breaches
Consolidate disaster recovery infrastructure, reducing costs and increasing manageability
Provide greater reliability with no interruptions for end-users, as IaaS can stay running even if a server goes down

Ability to expand and differentiate
Leverage pre-integrated options, including Azure, AWS and more, or integrate your own IaaS solutions
Focus time and resources on business growth, rather than IT infrastructure and support, and easily establish IT infrastructure in new regions
Differentiate your business, expand into new marketspaces, and increase revenue by incorporating robust IaaS platforms in your offerings
