What is Public Cloud?
Public cloud is computing infrastructure — servers, storage, networking — owned and operated by providers like Microsoft Azure or AWS and shared securely among many customers. You rent what you use, scale on demand and avoid owning hardware.
Why Public Cloud 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, public cloud 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 public cloud in your broader IT strategy will help you have more informed conversations with your IT provider and make better decisions for your business.

Frequently Asked Questions
What is public cloud?
Public cloud is shared, provider-operated infrastructure — like Azure or AWS — where businesses rent computing resources on demand instead of buying servers.
Is public cloud secure for business data?
Major platforms invest more in security than any SMB could, but configuration is your responsibility — most cloud breaches stem from customer misconfiguration, not platform failure.
What does public cloud cost?
You pay for what you consume, monthly. Costs are predictable when managed well, but unmanaged sprawl can creep — regular reviews keep spend optimised.
