Infrastructure as a Service (IaaS)

The lower end of managed cloud computing services is where hardware resources are provided by an external provider and managed for you. IaaS provides users access to computing resources such as networking, processing power, and data storage capacity.

IaaS helps users to use computing power or virtual machines without labor-intensive hardware investments or server management. Physically, the hardware resources are pulled from various networks and servers distributed across different data centers, all managed and maintained by the cloud service provider.

Examples of IaaS Cloud Computing Services:

• Amazon EC2
• Windows Azure
• Rackspace
• Google Compute Engine.

 

Features and Benefits of IaaS Cloud Computing Service:

• A typical infrastructure as a service offering saves time and money as the underlying hardware is set up and the service provider provides support.
• Resources are available on demand as and when required, so there is no wastage of unused resources and no delays in adding any resources.
• Utility-based pricing model, i.e., pays only for the resources you use.
