What is a major benefit of using Infrastructure-as-a-Service (IaaS)?

The major benefit of using Infrastructure-as-a-Service (IaaS) is global accessibility. IaaS provides a flexible and easily accessible platform that allows users to access computing resources over the internet from anywhere in the world, as long as they have an internet connection. This characteristic enables organizations to deploy applications and services in multiple regions without the need for substantial capital investment in physical hardware and infrastructure.

While cost efficiency is indeed a benefit of IaaS, the significance of global accessibility outstrips it, as it empowers businesses to quickly scale operations across different geographical locations without being tied to a specific data center. IaaS also facilitates disaster recovery and business continuity plans due to its ability to maintain resources in various locations simultaneously.

On-premise control is contrary to the very nature of IaaS, as this model emphasizes using cloud resources instead of managing physical infrastructure on-site. High security can vary among providers and configurations but is not inherently a guaranteed benefit of IaaS. Therefore, the capability to access infrastructure globally is pivotal, making global accessibility the most relevant advantage of IaaS.
