Security, identity, and compliance
Azure security stack
- Microsoft Entra ID with Conditional Access, PIM, and passwordless authentication
- Microsoft Defender for Cloud — CSPM and multi-cloud protection
- Microsoft Sentinel — cloud-native SIEM with 300+ connectors
- Microsoft Purview — data governance across Microsoft 365 and Azure
- 100+ compliance certifications including HIPAA BAA, FedRAMP High, DoD IL6, HITRUST
AWS security stack
- AWS IAM with fine-grained policies (no Conditional Access equivalent)
- Security Hub, GuardDuty, and Audit Manager
- Nitro Enclaves for sensitive data processing
- 90+ compliance certifications including FedRAMP High, DoD IL5
EPC Group view: Azure has a clear security and compliance advantage. Entra ID Conditional Access alone is a reason to choose Azure. Azure holds DoD IL6 — AWS does not.
Hybrid cloud: Azure Arc vs. AWS Outposts
Azure Arc uses a lightweight software agent. It runs on any server, edge device, or competing cloud — including AWS and GCP. No hardware purchase required.
AWS Outposts delivers proprietary hardware racks to your data center. You commit to a 3-year term at $200K–$1M+. You cannot manage non-AWS infrastructure with it.
EPC Group view: Azure Arc is the superior hybrid cloud solution. Start managing existing servers immediately. Multi-cloud management is a capability no other platform matches.
Cost comparison for common workloads
| Workload | Azure monthly cost | AWS monthly cost | Savings |
|---|---|---|---|
| 100 Windows Server VMs | $45,000 (Hybrid Benefit) | $78,000 | 42% with Azure |
| SQL Server Enterprise (8-core) | $1,200 (SQL MI + Hybrid Benefit) | $4,800 (RDS SQL Enterprise) | 75% with Azure |
| Kubernetes (50-node cluster) | $12,000 (AKS, free control plane) | $12,400 (EKS) | 3% with Azure |
For Microsoft workloads, Azure Hybrid Benefit reduces costs by 40–85%. For Linux-native workloads without Microsoft licensing, AWS is competitively priced.

Frequently asked questions
Is Azure or AWS better for enterprise organizations?
It depends on your technology stack. Azure is stronger for organizations using Microsoft 365, Active Directory, Windows Server, or Dynamics 365. AWS is stronger for Linux-native stacks needing the broadest cloud-native service catalog.
How does Azure pricing compare to AWS for enterprise workloads?
Azure Hybrid Benefit lets you reuse Windows Server and SQL Server licenses, saving up to 85% on VMs. For a typical 100-VM enterprise workload, Azure can be 30–40% less expensive when Hybrid Benefit is applied. AWS has no equivalent to license portability for Microsoft products.
Which cloud platform is more compliant for healthcare and HIPAA?
Both support HIPAA BAA, but Azure holds more compliance certifications overall (100+ vs. 90+). Azure Purview and Microsoft Compliance Manager simplify ongoing compliance management for healthcare organizations.
What is Azure Arc and how does it compare to AWS Outposts?
Azure Arc is a software-based agent that manages any server or cluster — on-premises, AWS, or GCP — without proprietary hardware. AWS Outposts delivers AWS hardware racks at significant upfront cost. Azure Arc is more flexible and cost-effective for hybrid scenarios.
How do Azure OpenAI and AWS Bedrock compare for enterprise AI?
Azure OpenAI offers exclusive access to GPT-4o, GPT-4.1, and o3. It ensures enterprise security and data privacy. In contrast, AWS Bedrock provides access to various third-party models through a single API.
When choosing between the two:
- Azure OpenAI is the best option for GPT-class models with Microsoft integration.
- Bedrock provides a wider variety of models.
Which platform is better for government and FedRAMP workloads?
Azure Government is purpose-built with physically isolated datacenters, FedRAMP High, DoD IL2–IL6, and ITAR compliance. AWS GovCloud supports FedRAMP High and DoD IL2–IL5 but lacks IL6 and ITAR. Azure Government also integrates more deeply with Microsoft products already used across federal agencies.
Can we use both Azure and AWS in a multi-cloud strategy?
Yes. Azure Arc simplifies multi-cloud management by extending Azure Policy, security monitoring, and Kubernetes management to AWS workloads. EPC Group designs multi-cloud architectures that use the strengths of each platform while maintaining centralized governance.
How long does an enterprise cloud migration to Azure typically take?
Timelines for projects vary from 3 to 12 months based on their scope. For example:
- A migration involving 50 servers typically takes about 3 to 4 months.
- A complete enterprise transformation, which includes 500 or more servers, database migrations, identity federation, and compliance setup, usually takes 6 to 12 months.
EPC Group speeds up timelines by 30 to 40% compared to industry averages by utilizing the Microsoft Cloud Adoption Framework.

Azure-native platform fabric the head-to-head usually misses
Most Azure vs AWS spreadsheets compare compute and database SKUs and stop there. The real platform delta for Microsoft-aligned enterprises is the Azure-native fabric that ships with the cloud: Azure Arc for hybrid and multi-cloud governance, Azure Bicep with Azure Resource Manager for declarative IaC, Microsoft Defender for Cloud as the unified CSPM and CWP layer, Microsoft Entra ID for workforce and workload identity, Azure Monitor for telemetry, Azure Front Door for global edge routing, and Azure Kubernetes Service tightly integrated with all of the above.
