🔀 Hybrid Architecture Patterns¶

Architecture patterns for hybrid cloud and multi-cloud analytics deployments.

🎯 Overview¶

Hybrid architectures combine on-premises infrastructure with Azure cloud services, enabling:

Gradual migration from legacy systems
Data sovereignty compliance
Latency optimization for edge workloads
Cost optimization through workload placement
Disaster recovery across environments

Global Data Distribution ¶

Patterns for distributing data across multiple Azure regions and on-premises locations.

Hub-and-Spoke Hybrid¶

Central Azure hub with on-premises spokes.

graph TB
    subgraph "Azure (Hub)"
        H1[Data Lake]
        H2[Synapse Analytics]
        H3[Azure Purview]
    end

    subgraph "On-Premises (Spoke 1)"
        S1A[SQL Server]
        S1B[File Shares]
    end

    subgraph "On-Premises (Spoke 2)"
        S2A[Oracle DB]
        S2B[Legacy Apps]
    end

    subgraph "Connectivity"
        C1[ExpressRoute]
        C2[VPN Gateway]
    end

    S1A --> C1
    S1B --> C1
    S2A --> C2
    S2B --> C2
    C1 --> H1
    C2 --> H1
    H1 --> H2
    H2 --> H3

Data Landing Zone¶

Staged data ingestion from multiple sources.

graph LR
    subgraph "On-Premises"
        O1[Source Systems]
    end

    subgraph "Landing Zone"
        L1[Self-Hosted IR]
        L2[Azure Data Factory]
        L3[Staging Storage]
    end

    subgraph "Analytics Platform"
        A1[Data Lake]
        A2[Processing]
        A3[Serving]
    end

    O1 --> L1
    L1 --> L2
    L2 --> L3
    L3 --> A1
    A1 --> A2
    A2 --> A3

🔧 Implementation¶

Self-Hosted Integration Runtime¶

{
    "name": "OnPremisesIR",
    "type": "Microsoft.DataFactory/factories/integrationRuntimes",
    "properties": {
        "type": "SelfHosted",
        "description": "Integration runtime for on-premises data sources"
    }
}

ExpressRoute Configuration¶

resource expressRouteCircuit 'Microsoft.Network/expressRouteCircuits@2023-05-01' = {
  name: 'er-hybrid-analytics'
  location: location
  sku: {
    name: 'Standard_MeteredData'
    tier: 'Standard'
    family: 'MeteredData'
  }
  properties: {
    serviceProviderProperties: {
      serviceProviderName: 'Equinix'
      peeringLocation: 'Washington DC'
      bandwidthInMbps: 1000
    }
  }
}
