Infrastructure as a Service
(IaaS) is an instant computing infrastructure, provisioned and managed over the internet. It’s one of the four types of cloud services
, along with software as a service (SaaS)
, platform as a service (PaaS)
, and serverless. IaaS
quickly scales up and down with demand, letting you pay only for what you use. It helps you avoid the expense and complexity of buying and managing your own physical servers and other datacentre infrastructure. Each resource is offered as a separate service component, and you only need to rent a particular one for as long as you need it. A cloud computing service provider, such as Azure
, manages the infrastructure, while you purchase, install, configure, and manage your own software—operating systems, middleware, and applications.
6 Reasons Why IAAS is Important
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.
1. Saves Cost
Saving infrastructure cost is the key advantage of IaaS. Organizations do not have to worry about maintaining or replacing hardware and networking equipment, minimizing downtime. IaaS incorporates a 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.
2. 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.
3. 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.
4. Focus on Business Development
More time to focus on growing your business instead of spending time and money making technological decisions and hiring IT staff to manage and maintain the technical infrastructure. Hence, if you use this service-based model, you can concentrate your time and resources on developing innovative applications and finding business solutions.
5. Increased Data Security
Since your data is the backbone of your organisation, you can’t afford to neglect data security. IaaS
gives you a physically secure IT environment, with enterprise-level data protection technologies at an affordable cost. One of the biggest barriers to cloud migration for C-level executives is their belief that data isn’t secure in the cloud. Yet IaaS means your organisation can take advantage of world-class data protection solutions, and stay up-to-date with encryption technologies and more with minimal effort.
6. Security training for network staff: Pen-Testing
allows security personnel to recognize and respond to a network attack properly. For instance, if the Pen-Tester is able to compromise a system without letting anyone know about it, this could indicate a failure to properly train staff on security monitoring.
