Infrastructure as a Service (IaaS) is one of the four (4) basic service models of cloud computing. The other three (3) models include Platform as a Service (PaaS), Software as a Service (SaaS) and Integration Platform as a Service (iPaaS) respectively. IaaS is an IT model which provides access to the physical or computing resource in a virtual domain. It outsources the physical resources that are used for support operations and components such as storage devices, virtual server space, IP addresses, networking, load balancers and network connections. These service providers are responsible for housing, running, upgrading and maintaining the resources as they own it themselves.
Some of the advantages of choosing IaaS as a service-based model for your business:
Saving infrastructure cost is the key advantage of IaaS as a model. Organizations do not have to worry about maintaining or replacing hardware and networking equipment, minimizing downtime. IaaS incorporates pay-as-you-go model which saves business management costs by accurately measuring what the company uses at any given time. This method allows you to only be charged for what you use.
Flexible and Scalable
Every business has numerous requirements and needs advanced and robust servers, storage systems and networking technologies. IaaS is flexible and scalable as you can easily scale up or down your resources whenever you want to. This helps the company to be responsive to the changing needs and opportunities.
Better Disaster Recovery
The disaster recovery plans of most organizations are expensive and difficult to manage. Organizations with several locations often choose disaster recovery and business continuity plans which make virtual management inconvenient. IaaS offers integrated disaster recovery infrastructure which helps reduce costs and efficiently control overall management of the environment.
Focus on Business Development
More time to focus on growing your business instead of spending time and money doing technological decisions and hiring IT staff to manage and maintain the technical infrastructure. Hence if you use service-based model, you can concentrate and utilize your time and resources on developing innovative applications and finding business solutions.
