Verdict: Azure is usually the better fit for small businesses and nonprofits already running Microsoft 365, Windows Server and Entra ID, because identity, licensing and management tools carry over. AWS is usually the better fit for software-first teams that want the broadest service catalog, mature serverless tooling and a large hiring pool. Both are secure, global and priced pay-as-you-go with commitment discounts.

Which should you choose?
Choose Microsoft Azure if…
- You already use Microsoft 365, Entra ID and Windows Server
- You own Windows Server or SQL Server licenses with Software Assurance you want to reuse
- You plan to roll out Microsoft 365 Copilot and want data and identity in one ecosystem
- Your IT team is Microsoft-trained and small
Choose Amazon Web Services if…
- You build and run your own software, especially serverless or Linux-based apps
- You want the widest catalog of managed services and third-party integrations
- Your developers or contractors already know AWS
- You want a broad choice of AI foundation models through one service
Azure and AWS are both mature, secure, global clouds, and either can run a small business or nonprofit well. The better choice depends mostly on what you already run, who will operate it, and which workloads you plan to move. This comparison focuses on organizations with roughly 5 to 250 employees.
What is the main difference between Azure and AWS?
The main difference is ecosystem fit: Azure extends the Microsoft stack, while AWS offers the broadest standalone cloud catalog. Azure shares identity (Microsoft Entra ID), management and licensing with Microsoft 365 and Windows Server. AWS was built cloud-first and leads in breadth of services, serverless maturity and third-party tooling.
For a typical small organization, that translates into a simple first question: is your organization already a Microsoft shop? If your staff sign in to Microsoft 365 every day and your servers run Windows, Azure removes a lot of friction. If your core asset is software your team builds, AWS often feels more natural.
How do Azure and AWS pricing models compare?
Both clouds charge pay-as-you-go by the second, hour or request, and both discount steady workloads in exchange for one- or three-year commitments. The details differ in ways that matter for small budgets.
- Azure offers reservations, Azure savings plans for compute, and Azure Hybrid Benefit, which lets you apply existing Windows Server and SQL Server licenses with Software Assurance. For Windows-heavy environments this is often the largest single saving.
- AWS offers Savings Plans, Reserved Instances and Spot capacity for interruptible work. Its free tier and serverless pricing make small, bursty workloads inexpensive.
- Both charge for data leaving the cloud (egress), storage transactions and premium support tiers. These line items often surprise first-time buyers.
Exact prices change frequently, so use the official Azure Pricing Calculator and AWS Pricing Calculator with your real server sizes. Our Azure cost optimization guide and AWS cost optimization guide cover the levers in depth.
Which cloud works better with Microsoft 365?
Azure works better with Microsoft 365 because both use the same Entra ID tenant for identity, conditional access and device management. You can extend existing users, groups and multi-factor authentication policies to Azure resources without a separate identity system.
AWS can federate with Entra ID through IAM Identity Center, and many organizations run it that way successfully. It simply adds a configuration layer and a second place to audit access. If you plan to deploy Microsoft 365 Copilot, keeping data in Microsoft services also simplifies governance; see Microsoft Copilot consulting.
How do Azure and AWS compare for AI workloads?
Both are strong for AI: Azure is the natural home for OpenAI models and Microsoft 365 Copilot extensions, while AWS offers broad model choice through Amazon Bedrock.
| AI need | Azure | AWS |
|---|---|---|
| Hosted large language models | Azure OpenAI and other models in Microsoft Foundry | Amazon Bedrock (Anthropic, Amazon, Meta, Mistral and others) |
| Retrieval-augmented generation (RAG) | Azure AI Search plus Foundry | Bedrock Knowledge Bases plus OpenSearch |
| Custom machine learning | Azure Machine Learning | Amazon SageMaker AI |
| Productivity AI for staff | Microsoft 365 Copilot and Copilot Studio | Amazon Q Business |
For most small organizations, the AI choice should follow the data. If your documents live in SharePoint and Teams, Azure and Copilot are the shorter path. Our Azure AI services overview and RAG architecture guide go deeper.
Which is better for Windows Server and SQL Server?
Azure is generally better for Windows Server and SQL Server workloads. Azure Hybrid Benefit, Azure SQL Managed Instance and options for extended security updates on older Windows versions reduce both cost and migration risk.
AWS runs Windows and SQL Server reliably and offers Amazon RDS for SQL Server. License-included pricing on AWS is straightforward, but bringing your own Microsoft licenses is more restricted than on Azure under current Microsoft licensing terms.
Which is better for custom software and serverless apps?
AWS has the edge for serverless and cloud-native software because AWS Lambda, Step Functions, DynamoDB and EventBridge form the most mature, widely documented serverless toolkit. Azure Functions, Container Apps and Cosmos DB are capable alternatives, and .NET teams often prefer them.
If you build software, the skills of your developers matter more than feature lists. A team fluent in one cloud will ship faster there. See our AWS serverless guide for patterns.
What about security, compliance and data location?
Security and compliance are comparable: both providers hold the major certifications, and real risk comes from how you configure them. Each offers a native security posture tool (Microsoft Defender for Cloud and AWS Security Hub), centralized logging and policy guardrails (Azure Policy and AWS Organizations service control policies).
For Seattle-area organizations, Azure's West US 2 region is located in Washington State, while AWS's nearest major region, us-west-2, is in Oregon. Both keep data in the United States. Health data subject to Washington's My Health My Data Act or HIPAA can be hosted on either, provided you sign the provider's Business Associate Agreement where required and configure access controls correctly.
How do support plans and partner ecosystems compare?
Both providers offer tiered paid support and large partner networks, so the practical difference is which ecosystem your vendors and staff already know. Azure support plans range from basic billing help to round-the-clock technical support, and AWS offers a similar ladder. Both include free billing and account support.
Microsoft's partner network is closely tied to Microsoft 365 and licensing, which helps organizations that want one partner for productivity, identity and cloud. AWS has a very large marketplace and consulting partner base, especially for software and data workloads. Check that your key line-of-business software vendors support your chosen cloud before you commit.
How should a small business decide?
Decide by scoring your current stack, team skills and top three workloads, then running a small pilot. A practical sequence:
- List every server, application and data store, and note which are Windows, Linux or SaaS.
- Note your identity provider and productivity suite.
- Identify who will operate the cloud day to day, and what they already know.
- Price your top workloads in both calculators using realistic sizes and commitments.
- Pilot one non-critical workload for two to four weeks.

Frequently asked questions
Is Azure or AWS cheaper for a small business?
Neither is cheaper across the board. For Windows Server and SQL Server workloads, Azure is often less expensive because Azure Hybrid Benefit lets you reuse licenses you already own. For Linux and serverless workloads, costs are usually comparable, and the deciding factor is how well you right-size, schedule and commit. Both providers offer pricing calculators and commitment discounts, so model your actual workloads before deciding.
Which cloud is easier to learn for a small IT team?
Azure is usually easier for teams that already administer Microsoft 365 and Active Directory, because Entra ID, PowerShell and the portal feel familiar. AWS is often easier for developers who already use it or who prefer command-line and infrastructure-as-code workflows. Training is available for both, and Microsoft Learn and AWS Skill Builder offer free learning paths.
Can I use both Azure and AWS?
Yes, but most small organizations should not start that way. Running two clouds doubles the identity, networking, security and billing work. A common practical pattern is a primary cloud for most workloads, with Entra ID as the single identity provider, and a second cloud only for a specific service that is clearly better there.
Is Azure or AWS more secure?
Both meet the same major compliance frameworks, including SOC 2, ISO 27001, HIPAA eligibility and FedRAMP. Security outcomes depend far more on configuration than on the provider. Misconfigured storage, weak identity controls and missing logging cause most cloud incidents on either platform. Use Microsoft Defender for Cloud or AWS Security Hub to find and fix configuration gaps.
Which cloud is better for nonprofits?
Nonprofits that already receive Microsoft 365 nonprofit licensing usually find Azure simpler, since identity and grants sit in the same Microsoft relationship. AWS also offers nonprofit credit programs. Eligibility, grant amounts and terms change, so check current program details with Microsoft, AWS or TechSoup before planning a budget around them.
