"Moving to the cloud" is one of the most common IT decisions Perth businesses face — but it's often unclear what that actually means, what it costs, or where to start. This guide breaks down cloud computing for Perth businesses in plain English: what Microsoft Azure and Microsoft 365 each do, when you need them, and what to expect on price.
What is cloud computing (for a business)?
Cloud computing means running your IT — email, files, applications, servers — on secure infrastructure managed in professional data centres, accessed over the internet, instead of on hardware sitting in your office. For a Perth business, that usually translates to less on-premises hardware to buy and maintain, easier remote work, and predictable monthly costs instead of large upfront capital spend.
Azure vs Microsoft 365 — what's the difference?
These two Microsoft cloud products get confused constantly, so here's the simple version:
- Microsoft 365 is what your team uses every day — email (Exchange Online), Teams, SharePoint, OneDrive, and the Office apps. It replaces an in-office email server and file server for most businesses.
- Microsoft Azure is the underlying cloud platform for hosting servers, line-of-business applications, databases and infrastructure. It's where you move workloads that used to run on a physical server in your office.
Most Perth businesses use both: Microsoft 365 for productivity, and Azure to host any servers or applications that can't live in Microsoft 365 alone.
When does a Perth business need Azure?
You likely need Azure (not just Microsoft 365) if you:
- Run a line-of-business application that requires a Windows server
- Have an ageing on-premises server you want to retire
- Need a remote desktop / virtual desktop environment for staff
- Want disaster recovery or off-site hosting for critical systems
If you only need email, files and collaboration, Microsoft 365 on its own is often enough.
What does cloud computing cost in Perth?
Two different pricing models, so it helps to separate them:
- Microsoft 365 is a fixed per-user, per-month licence — you pick a plan (from basic email up to Business Premium with advanced security) and pay per staff member.
- Microsoft Azure is consumption-based — you pay for the compute, storage and services you actually use. That flexibility is powerful but can waste money if left unmanaged, which is why we right-size the environment, apply reserved-instance discounts, and monitor spend monthly.
The best way to get a real number is a free assessment, where we size your environment and estimate the monthly cost before you commit.
How does cloud migration work?
We handle cloud migration end-to-end for Perth businesses: assess what you have, plan the move around your workload to minimise downtime, migrate your email, files and any servers, then secure and optimise the environment. Crucially, your data is hosted in Australian regions, which matters for privacy and data-sovereignty requirements.
Is the cloud secure enough for my data?
Yes — a properly configured cloud environment is generally more secure than a typical small-business server, with enterprise-grade encryption, MFA, threat detection and compliance certifications. The risk comes from misconfiguration and weak passwords, which is exactly what we lock down during migration and manage ongoing. (See our cyber security services in Perth.)
