Azure Hybrid Cloud: An Overview

Azure Hybrid Cloud solutions enable organizations to seamlessly integrate their on-premises IT environments with Microsoft Azure. This approach allows businesses to leverage the scalability, flexibility, and innovation of the cloud while maintaining control over sensitive data and existing infrastructure.

By bridging the gap between your private datacenter and the public cloud, Azure Hybrid Cloud empowers you to:

  • Optimize resource utilization and cost.
  • Enhance business continuity and disaster recovery capabilities.
  • Accelerate application modernization and development.
  • Meet compliance and regulatory requirements.
  • Extend existing investments in IT infrastructure.

Key Concepts in Azure Hybrid Cloud

Connectivity

Establishing secure and reliable connections between your on-premises network and Azure is fundamental. This is typically achieved through:

  • Azure VPN Gateway: Secure site-to-site VPN tunnels.
  • Azure ExpressRoute: Dedicated private network connection.

Identity and Access Management

Unified identity management across your hybrid environment is crucial for security and user experience.

  • Azure Active Directory (Azure AD): Cloud-based identity and access management.
  • Azure AD Connect: Synchronizes on-premises Active Directory with Azure AD.
  • Azure AD Domain Services: Managed domain services for Azure VMs.

Data Management

Strategies for data storage, migration, and synchronization across hybrid environments.

  • Azure Arc: Manages resources across on-premises, edge, and multi-cloud environments.
  • Azure File Sync: Centralize file shares in Azure Files.
  • Azure Data Box: Securely transfer large amounts of data to Azure.

Application Modernization

Modernizing existing applications to run effectively in a hybrid model.

  • Azure Kubernetes Service (AKS) / Azure Arc-enabled Kubernetes: Orchestrate containerized applications.
  • Azure Stack: Extend Azure services and capabilities to your datacenter.

Key Azure Services for Hybrid Cloud

Azure Arc

Govern, manage, and secure resources across your hybrid and multi-cloud environments from a single control plane.

Azure Stack

Bring Azure innovation to your datacenter and edge locations. Deploy Azure services like compute, storage, and networking consistently.

Azure VPN Gateway

Connect your on-premises networks securely to Azure virtual networks via a site-to-site VPN tunnel.

Azure ExpressRoute

Establish private connections between Azure datacenters and infrastructure that is on-premises or in a colocation environment.

Azure Active Directory

A comprehensive identity and access management solution for cloud and hybrid environments.

Common Hybrid Cloud Scenarios

  • Disaster Recovery: Replicate on-premises workloads to Azure for business continuity.
  • Datacenter Extension: Burst workloads to Azure during peak demand or for specific projects.
  • Modernizing Legacy Applications: Migrate and modernize applications incrementally.
  • Edge Computing: Deploy Azure services closer to data sources with Azure Stack.
  • Data Sovereignty and Compliance: Keep sensitive data on-premises while leveraging cloud services.
