What is Virtualisation?
Virtualisation lets one physical server run many independent virtual machines, each with its own operating system and applications, by abstracting the hardware through a hypervisor. It is the foundational technology behind cloud computing and modern server rooms alike.
Why Virtualisation 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, virtualisation can make a real difference in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding the role of virtualisation in your broader IT strategy will help you have more informed conversations with your IT provider and make better decisions for your business.
