Azure or AWS: which should a small business use?

For most Australian small businesses the honest answer is whichever platform fits what you already run. If your identity and productivity live in Microsoft 365, Azure integrates most naturally. AWS has the broader service catalogue and often suits specific workloads better. Both are mature, both have Australian regions, and the platform matters less than the design.

This comparison attracts a lot of noise for a decision that, at small business scale, is rarely close and rarely critical. You are not choosing between good and bad. You are choosing which of two excellent platforms will host a handful of workloads, and the factors that actually determine whether the outcome is good, how it is designed, who manages it and whether anyone reviews the bill, are identical either way.

The case for Azure in a Microsoft-centric business is integration, and it is a real advantage rather than a marketing one. Your identity already lives in Entra ID, so authentication, conditional access and single sign-on extend naturally rather than being bridged. Administration happens in a portal your provider already works in. Licensing can interact usefully, since existing Windows Server and SQL Server licences may carry across and change the arithmetic. For a business whose world is already Microsoft 365, Azure is the path of least friction, and friction is cost.

The case for AWS is breadth and maturity. It has the largest service catalogue, the deepest bench of engineers who know it, and for certain workloads it is simply the better-trodden path. It is also entirely comfortable hosting Windows workloads, which surprises people who assume it is a Linux platform. We run client environments on it, including a 24/7 freight and logistics operation at 99.99% uptime with SD-WAN across five sites, and a general practice whose clinical systems moved off a single vulnerable server. Neither of those was a Microsoft-versus-Amazon decision; both were workload decisions.

It is worth naming what is genuinely the same on both, because a great deal of comparison content implies otherwise. Both run Windows and Linux workloads, both offer managed databases, both provide Australian regions, both have mature backup and disaster recovery options, both meet the security standards an Australian small business will be asked about, and both are used by organisations far larger and more demanding than yours. If a feature comparison is being used to justify a recommendation at this scale, the feature is rarely the real reason.

In practice the choice usually gets made by three things, none of which is a feature comparison. What your line-of-business software vendor supports and has actually deployed before, which is worth asking directly. What your provider genuinely runs well, since a platform administered competently beats a theoretically better one administered occasionally. And whether existing licences change the maths. If those three point the same way, take the hint and stop researching.

Two things matter more than the choice itself, and both get less attention than they deserve. The first is region: both operate Australian data centres, and selecting one keeps latency low and data onshore, which some contracts and obligations require. Confirm it in writing, because the default at sign-up is not always the nearest region. The second is design, which is where nearly all the cost and reliability difference actually lives. A workload lifted straight into an oversized virtual machine running around the clock is expensive on either platform, and a well-designed environment is affordable on either.

One more factor deserves weight for a small business, and it is people rather than technology: who else can work on it. If your provider disappeared tomorrow, how easily could you find someone competent on the platform you chose, at a price you would pay? Both platforms pass this test comfortably in Australian capital cities, which is part of why the choice is low-stakes, and it is exactly the question worth asking about any less mainstream option a provider might recommend instead.

The honest caveat is that we are partners with both, which shapes this article in a way worth disclosing: we have no reason to push you either way, and that is precisely why the recommendation follows your workload rather than a vendor relationship. A provider who only ever recommends one platform may be right, and is worth asking why. If you want the choice made against what you actually run, call 1800 456 567.
