description: OCI to Azure service mapping for competitive positioning.
---

service_mapping:
  database:
    - oci: "ADB-S"
      azure: "Azure SQL Managed Instance / Azure Database for PostgreSQL"
      oci_advantage: |
        ADB-S runs actual Oracle Database. Azure SQL MI is SQL Server only.
        No native Oracle database service on Azure.
        Oracle on Azure VMs loses Exadata performance and autonomous operations.
      azure_advantage: "Native SQL Server support if migrating from SQL Server."
    - oci: "ExaCS"
      azure: "Oracle Database@Azure (ExaCS in Azure datacenters)"
      notes: |
        Oracle Database@Azure is ExaCS running in Azure datacenters with
        direct connectivity to Azure services. Available in select regions.
        This is a partnership offering, not a competitive comparison.

  compute:
    - oci: "OCI Compute"
      azure: "Azure Virtual Machines"
      oci_advantage: "Flexible shapes, lower cost for Oracle workloads."
      azure_advantage: "Deeper Microsoft ecosystem integration, Hybrid Benefit."

  networking:
    - oci: "OCI Interconnect with Azure"
      azure: "Azure ExpressRoute with OCI"
      notes: |
        OCI and Azure have a direct interconnect in multiple regions.
        Low-latency (<2ms) connectivity for hybrid deployments.
        Enables Oracle DB on OCI with apps on Azure.

pricing_comparison:
  notes: |
    For Oracle workloads, OCI is significantly cheaper:
    - No Oracle license surcharge on OCI
    - Exadata performance not available on Azure
    - BYOL works better on OCI
    - Data egress cheaper on OCI

common_objections:
  - objection: "We're an Azure shop — Microsoft is our strategic partner"
    response: |
      Oracle Database@Azure allows running OCI database services directly
      in Azure datacenters. Your team stays in the Azure portal while
      getting OCI database performance and economics.
  - objection: "We prefer Azure SQL for our databases"
    response: |
      For SQL Server workloads, Azure SQL is excellent. For Oracle database
      workloads that must remain Oracle, OCI provides superior performance
      and cost. Consider multi-cloud: Azure for .NET/SQL Server, OCI for Oracle.
