Benefits of Infrastructure as a Service (IaaS)

Infrastructure as a Service (IaaS) is a provision model in which an organization outsources the equipment used to
support operations, including storage, hardware, servers and networking components. The service provider owns the
equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis.

There’s already considerable use of IaaS among IT leaders in the hospitality, healthcare and retail industries. Benefits of IaaS include:

• Cost reduction
  
• Automation
  
• Scalability
  
• Utility service
  
• Flexibility
  

Cost Reduction:  Reduces TCO (Total Cost of Ownership) – Changes the cost from Capital expense (Capex) to Opex (Operational expense) for an enterprise. No need to buy an asset to use that asset and reduces other related costs of maintenance and support.  Reduced energy consumption by using a more efficient per use model. Save on internal labor hours by passing various tasks to the provider who utilizes more automation. 

Automation: Automating daily tasks that bog down internal IT teams produces quick results.  IaaS can increase the automation in a given environment and decrease internal labor hours.  Frees an organization to leverage and focus their time and resources in bringing innovations in applications and solutions.

Scalability: Use IT resources to their maximized efficiency.  The high and low peak times of your IT infrastructure are no longer using equal amounts of energy and labor with IaaS.  

Utility Service: IaaS follows a utility service model – pay per use / pay per go subscription based model. Availability of ready to go iaas offerings with limited time for implementation and customization (if provided). IaaS usage is metered and priced on the basis of units (or instances) consumed. Pay for what you use and when you use.

Flexible offering: Access infrastructure from anywhere, any location on any device.

Cloud infrastructure services, also known as IaaS, deliver computer infrastructure – typically a platform virtualization environment – as a service, along with raw (block) storage and networking. 

Characteristics and components of IaaS include:

• Utility computing service and billing model
  
• Automation of administrative tasks
  
• Dynamic scaling
  
• Desktop virtualization
  
• Policy-based services
  
• Internet connectivity
  

IaaS is one of three main categories of cloud computing service. The other two are Software as a Service (SaaS) and Platform as a Service (PaaS).

IaaS is sometimes referred to as Hardware as a Service (HaaS).
