Azure vs AWS vs Google Cloud for SMEs
For Melbourne SMBs already using Microsoft 365, Azure is the natural cloud platform — shared identity through Entra ID, native Microsoft Defender integration, and Australian data residency in local Azure regions give it a practical advantage over AWS and Google Cloud in most scenarios.

Why the platform choice matters more than raw specs
Cloud platform comparison articles often focus on raw pricing, feature lists, and benchmark performance. For Melbourne SMBs, the more important decision factors are: which platform integrates with the software you already use, where your data will reside (Australian data residency requirements apply to many SMBs), what support model is available, and which platform your IT provider is best equipped to manage. A cheaper cloud platform that your MSP cannot manage effectively, that requires a separate identity system, or that stores data offshore creates more operational friction than the cost saving justifies.
Microsoft Azure — advantages for Microsoft 365 businesses
Azure's primary advantage for Melbourne SMBs is integration with Microsoft 365. Entra ID (Azure Active Directory) is the shared identity platform — users authenticate to Azure resources with the same credentials and MFA policies as Microsoft 365. Microsoft Defender for Cloud provides unified security monitoring across Azure virtual machines, storage, and databases. Azure regions in Sydney and Melbourne provide Australian data residency. Azure Backup and Azure Site Recovery integrate with on-premises environments and cloud workloads natively. For businesses already paying for Microsoft 365 Business Premium, some Azure security tools have reduced cost or are included.
AWS — where it leads
Amazon Web Services has the broadest service catalogue of the three major platforms and the largest global footprint. AWS is typically the preferred platform for software development workloads, data analytics, container orchestration (Kubernetes/ECS), and workloads that require services not yet available on Azure or Google Cloud. For Melbourne SMBs, AWS is most compelling when the business has specific technical requirements — a development team building cloud-native applications, a data warehouse workload, or a need for a service with no Azure equivalent. AWS Australia regions are located in Sydney.
Google Cloud — when it fits for Melbourne SMBs
Google Cloud Platform (GCP) is the platform of choice for organisations with deep Google Workspace (Gmail, Docs, Drive, Meet) deployments, data analytics workloads using BigQuery, and machine learning applications. For most Melbourne SMBs using Microsoft 365, GCP introduces a second identity system and management toolset without delivering proportionate benefit. GCP is worth evaluating if the business has existing Google Workspace licences and is considering cloud infrastructure to complement them, or if specific GCP services (BigQuery, Vertex AI) are required for the business's data strategy.
Identity and security integration comparison
For Microsoft 365 businesses, Azure wins the identity comparison outright — Entra ID is already the identity provider, and Azure resources join the same identity and access management system. AWS uses IAM (Identity and Access Management) which is separate from Entra ID — federation is possible but requires configuration and maintenance. GCP uses Google Identity, which is also separate. Security monitoring integration follows the same pattern: Microsoft Defender for Cloud provides native, low-configuration monitoring for Azure; AWS Security Hub and Google Security Command Center require separate configuration and do not integrate with Microsoft 365 telemetry natively.
How CTS recommends cloud platforms for Melbourne businesses
CTS recommends Azure for the majority of Melbourne SMB workloads because of the Microsoft 365 integration, shared identity management, local data residency, and CTS's deep Azure expertise. CTS designs and manages Azure environments — virtual machines, Azure Backup, Azure Site Recovery, Azure Virtual Desktop, and Microsoft Defender for Cloud — as part of the managed IT service. For businesses with specific workloads that are better served by AWS or GCP, CTS provides advisory and can manage multi-cloud environments.
Frequently asked questions
Does Microsoft Azure store data in Australia?
Yes. Azure has data centre regions in Sydney (Australia East) and Melbourne (Australia Southeast). By selecting these regions when provisioning Azure services, Australian businesses can ensure that their data is stored and processed within Australia. This is important for organisations subject to Australian data residency requirements under the Privacy Act or sector-specific regulations.
Can we use more than one cloud platform at once?
Yes — many Melbourne SMBs run a primary platform (typically Azure for Microsoft 365 integration) alongside a secondary platform for specific workloads, such as AWS for a development environment or GCP for BigQuery analytics. CTS manages multi-cloud environments but recommends minimising platform count where possible, since each additional platform adds identity, security monitoring, and management overhead.
