What is IaaS (Infrastructure as a Service)?
IaaS provides on-demand access to computing resources—servers, storage, and networking—over the internet. You pay only for what you use, and the cloud provider manages the underlying infrastructure.
Why IaaS matters for Australian businesses
Cloud computing has become the backbone of modern business IT, offering flexibility, scalability, and cost efficiency that on-premises infrastructure cannot match. For Australian businesses, understanding cloud terminology helps you make informed decisions about which services to adopt and how to optimise your cloud spend.
For small and medium businesses in particular, iaas plays a key role in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding iaas will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is IaaS?
Infrastructure as a Service (IaaS) provides core computing resources such as servers, storage and networking over the internet, so you rent infrastructure on demand instead of buying and maintaining hardware.
How is IaaS different from SaaS and PaaS?
IaaS gives you the raw infrastructure to manage; PaaS adds a platform for building applications; SaaS delivers finished software. IaaS offers the most control and the most responsibility.
What is IaaS used for?
Hosting servers and applications, scalable storage, disaster recovery and test environments, particularly where businesses want cloud flexibility while keeping control of the operating systems and software.
