AWS Hybrid Cloud Services for Your Enterprise
AWS hybrid cloud services enable enterprises to extend their on-premises infrastructure into the cloud, creating a unified environment that combines the control of local data centers with the scalability and innovation of Amazon Web Services. For organizations with regulatory requirements, latency-sensitive applications, or significant existing infrastructure investments, hybrid cloud architectures provide the flexibility to modernize incrementally without a disruptive full-cloud migration.
At EPC Group, we provide vendor-agnostic cloud advisory services. While our primary expertise is in the Microsoft ecosystem, our 28+ years of enterprise consulting experience includes helping organizations evaluate, implement, and manage multi-cloud and hybrid strategies that span Azure, AWS, and on-premises environments.
Core AWS Hybrid Cloud Services
AWS offers several purpose-built services for hybrid cloud architectures, each addressing different enterprise requirements for on-premises cloud extension.
AWS Outposts
AWS Outposts brings native AWS infrastructure, services, and APIs to virtually any on-premises facility. Outposts are fully managed racks of AWS compute and storage hardware installed in your data center, providing a consistent hybrid experience.
- Outposts Racks: Full 42U racks with EC2 instances, EBS storage, and support for services like ECS, EKS, RDS, and EMR running locally in your data center
- Outposts Servers: Individual 1U or 2U servers for smaller or edge locations that need local compute and storage with AWS management
- Use Cases: Low-latency applications (manufacturing, healthcare imaging), data residency requirements, and local data processing before cloud upload
- Pricing: Outposts is available as a 3-year subscription with upfront, partial upfront, or no-upfront payment options
AWS Storage Gateway
Storage Gateway connects on-premises environments with AWS cloud storage, providing seamless integration for backup, archiving, and disaster recovery.
- S3 File Gateway: Presents S3 buckets as NFS or SMB file shares for on-premises applications
- FSx File Gateway: Provides low-latency access to Amazon FSx for Windows File Server from on-premises environments
- Volume Gateway: Block storage volumes backed by S3 with point-in-time snapshots for disaster recovery
- Tape Gateway: Virtual tape library (VTL) that replaces physical tape infrastructure with cloud-backed virtual tapes
AWS Direct Connect
Direct Connect establishes dedicated private network connections between your on-premises data centers and AWS. This bypasses the public internet, providing consistent network performance, reduced bandwidth costs, and enhanced security for hybrid workloads.
- Connection speeds from 50 Mbps to 100 Gbps
- Dedicated and hosted connection options
- Supports both IPv4 and IPv6 traffic
- Integrates with AWS Transit Gateway for multi-VPC and multi-region connectivity
Amazon ECS/EKS Anywhere
ECS Anywhere and EKS Anywhere extend AWS container orchestration to on-premises infrastructure. Organizations can use the same AWS container management tools and APIs for workloads running locally, enabling consistent container deployments across hybrid environments.
AWS vs. Azure Hybrid Cloud: Enterprise Comparison
Both AWS and Microsoft Azure offer mature hybrid cloud capabilities, but they differ in approach, integration depth, and target use cases.
| Capability | AWS | Azure |
|---|---|---|
| On-Premises Hardware | Outposts (racks/servers) | Azure Stack HCI, Azure Stack Hub |
| Multi-Cloud Management | Limited (ECS/EKS Anywhere) | Azure Arc (any infrastructure) |
| Identity Integration | AWS IAM, AD Connector | Native AD / Entra ID sync |
| Private Connectivity | Direct Connect | ExpressRoute |
| Productivity Suite | No native equivalent | Microsoft 365 native integration |
For organizations deeply invested in the Microsoft ecosystem (Active Directory, Microsoft 365, Dynamics 365), Azure typically provides a more cohesive hybrid experience. AWS excels for organizations with custom-built applications and diverse technology stacks.
Enterprise Hybrid Cloud Architecture Patterns
Successful hybrid cloud implementations follow established architecture patterns that balance performance, security, and cost optimization.
- Cloud Bursting: Run baseline workloads on-premises and burst to AWS during peak demand. Common in retail (seasonal traffic) and media (event-driven spikes).
- Data Tiering: Keep frequently accessed data on-premises for low latency while archiving historical data to S3 Glacier or Azure Archive Storage for cost savings of 90%+.
- Disaster Recovery: Maintain production workloads on-premises with automated failover to AWS or Azure for business continuity. AWS CloudEndure and Azure Site Recovery automate this process.
- Development/Production Split: Run development and testing environments in the cloud for agility while keeping production workloads on-premises for compliance or performance reasons.
- Edge Processing: Process data locally at edge locations using AWS Outposts or Azure Stack Edge, then aggregate and analyze results in the cloud.
Security Considerations for Hybrid Cloud
Hybrid cloud environments introduce security complexity because data and applications span multiple trust boundaries. Key security requirements include:
- Unified Identity: Consistent authentication and authorization across on-premises and cloud environments using federated identity
- Network Segmentation: Proper network isolation between on-premises and cloud resources with firewall rules and security groups
- Encryption in Transit: All data moving between on-premises and cloud must be encrypted using VPN tunnels or dedicated private connections
- Centralized Logging: Aggregate security logs from all environments into a single SIEM (Microsoft Sentinel or AWS Security Hub) for unified threat detection
- Compliance Consistency: Apply the same compliance controls (HIPAA, SOC 2, FedRAMP) across both on-premises and cloud environments

Frequently Asked Questions
What is the difference between hybrid cloud and multi-cloud?
Hybrid cloud combines on-premises infrastructure with one or more public clouds, creating a unified environment where workloads can move between locations. Multi-cloud refers to using multiple public cloud providers (e.g., AWS and Azure) without necessarily including on-premises infrastructure. Many enterprises adopt both strategies simultaneously -- using Azure and AWS for different workloads while maintaining some on-premises infrastructure.
Is AWS Outposts worth the investment?
AWS Outposts makes sense for organizations that need AWS-native services running locally for latency, data residency, or regulatory reasons. The investment is significant (3-year commitments), so it is best suited for organizations with clear requirements that cannot be met by cloud-only or VPN-connected architectures. For many organizations, a standard hybrid architecture using Direct Connect or VPN connections provides sufficient hybrid capability at lower cost.
Can we use both AWS and Azure in a hybrid architecture?
Yes, and many large enterprises do. A common pattern uses Azure for Microsoft 365 integration, identity management, and Power BI analytics while running custom applications and data processing workloads on AWS. The key is implementing consistent security policies, unified monitoring, and clear governance across both platforms. Azure Arc can manage resources across both Azure and AWS from a single portal.
How do we maintain compliance across hybrid environments?
Compliance in hybrid environments requires consistent controls across all locations. This includes unified identity management, encryption standards, access logging, vulnerability scanning, and policy enforcement. Tools like Azure Policy, AWS Config, and third-party CSPM platforms can enforce compliance rules across hybrid and multi-cloud environments. EPC Group designs compliance architectures that maintain HIPAA, SOC 2, and FedRAMP standards regardless of where workloads run.
Should we start with AWS or Azure for our hybrid cloud?
The decision depends on your existing technology investments and primary use cases. If your organization uses Microsoft 365, Active Directory, and Microsoft development tools, Azure provides the most seamless hybrid experience. If your applications are primarily custom-built using open-source technologies and you need the broadest service catalog, AWS may be a better fit. EPC Group provides objective assessment to help you make the right choice for your specific situation.
