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 virtualised 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 virtualisation 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 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
