Oracle Fusion Runs Best on OCI.
Your Microsoft Stack Lives in Azure. We Connect Both.
The OCI-Azure Interconnect is a private dedicated network link between Oracle Cloud Infrastructure and Microsoft Azure data centres — enabling Oracle Fusion on OCI to communicate with Microsoft Entra ID, Microsoft 365, Microsoft Sentinel, and Azure analytics services over a sub-2ms private connection without touching the public internet. It is the only cloud interconnect of its kind.Symhas designs and deploys OCI-Azure multi-cloud architecture — Oracle Fusion on OCI for ERP performance and cost, Azure for Microsoft ecosystem integration, identity, and security — with the OCI-Azure Interconnect providing the private backbone between them, and a single unified security monitoring posture across both clouds.

OCI–Azure Interconnect Design & DeploymentFastConnect · ExpressRoute · Private peering · Sub-2ms · No public internet
The OCI-Azure Interconnect uses Oracle FastConnect on the OCI side and Azure ExpressRoute on the Azure side — a dedicated private circuit through a shared co-location point, providing a private high-bandwidth connection between Oracle Fusion on OCI and Azure services without traversing the public internet.
FastConnect circuit — OCI side of the interconnect via Oracle FastConnect at co-location point
ExpressRoute circuit — Azure side via Microsoft partner at the same co-location facility
Private peering — BGP routing between OCI VCN and Azure VNet via the interconnect
Sub-2ms latency — measured and validated at interconnect provisioning
Redundant circuits — dual FastConnect and ExpressRoute circuits for interconnect high availability
Oracle Fusion on OCI communicates with Azure AD, Sentinel, and M365 over a private sub-2ms link — no public internet
Microsoft Entra ID as Identity Provider for OCISAML · OIDC · OCI IAM · Entra ID · SSO · MFA
Microsoft Entra ID federated to OCI IAM as the identity provider — users authenticate to Oracle Fusion using their Microsoft credentials with Entra ID Conditional Access enforcing MFA and device compliance before access is granted to OCI-hosted applications.
OCI IAM Identity Domain configuration — Entra ID as SAML or OIDC identity provider
Oracle Fusion SSO — users sign in to Oracle Fusion with their Microsoft credentials via Entra ID
Conditional Access — MFA and device compliance enforced by Entra ID before OCI access is granted
SCIM provisioning — Entra ID users and groups provisioned to OCI IAM automatically
PIM for OCI admin roles — OCI administrator roles managed via Entra PIM approval workflow
One identity for Oracle Fusion and Azure — users sign in once, Entra ID Conditional Access protects both
Unified Security Monitoring Across OCI and AzureMicrosoft Sentinel · OCI Cloud Guard · Syslog · CEF · Unified incidents
Microsoft Sentinel as the unified SIEM across OCI and Azure — OCI Cloud Guard events and OCI audit logs forwarded to Sentinel via the OCI-Azure Interconnect, creating a single incident queue that correlates threats across both cloud environments with cross-cloud investigation capability.
OCI audit log connector — OCI audit events forwarded to Microsoft Sentinel via the interconnect
OCI Cloud Guard findings — security findings from OCI Cloud Guard in the Sentinel incident queue
Oracle Fusion application logs — Oracle Fusion security-relevant events forwarded to Sentinel
Cross-cloud correlation — Sentinel analytics rules detecting attack patterns spanning OCI and Azure
Unified incident response — single incident queue, single investigation workflow for both clouds
One SIEM for both clouds — an attacker moving between OCI and Azure is detected by the same analytics rule
Azure Analytics on Oracle Fusion DataAzure Synapse · Fabric · Power BI · Private Link · Oracle Fusion data
Oracle Fusion financial, HCM, and SCM data accessed by Azure analytics services via the OCI-Azure Interconnect — Azure Synapse Analytics or Microsoft Fabric connecting to Oracle Autonomous Database on OCI over the private link, without data leaving the private network to reach analytics workloads.
Azure Synapse or Fabric — analytics workspace connecting to Oracle Fusion data on OCI
Private Link via Interconnect — Oracle Autonomous Database accessed from Azure over private link
Oracle Fusion REST API — operational data available to Azure Logic Apps and Power Automate
Power BI — financial and operational dashboards on Oracle Fusion data via DirectQuery over private link
Data residency — Oracle Fusion data never leaves the OCI-Azure private network for analytics workloads
Azure analytics power applied to Oracle Fusion data — over the private interconnect, never via the public internet

OCI + Azure Connected. ↓33% Cost. Unified Security Monitoring.

A global asset management firm needed Oracle Fusion Finance on OCI for performance and cost, Microsoft Entra ID for identity across 340 users, Microsoft Sentinel for security operations, and Azure analytics for financial reporting — all as a single integrated environment, not two separate clouds.

Symhas designed and deployed the full OCI-Azure multi-cloud architecture — OCI landing zone with Oracle Fusion on Exadata, Azure landing zone with Entra ID governance and Sentinel, OCI-Azure Interconnect providing the private backbone, and unified security monitoring across both clouds in a single Sentinel incident queue.

Why Symhas
Azure Expertise Built from Production Deployments.
Interconnect CIDR Planning Before Anything Is DeployedOCI VCN and Azure VNet CIDR overlap is the most common OCI-Azure Interconnect failure. Symhas plans and validates all CIDR ranges across both clouds before provisioning any networking — overlap discovered in design, not in a broken BGP route.
Entra ID Federation Tested With All User PopulationsOracle Fusion SSO fails for specific user types when federation is not configured comprehensively. Symhas tests Entra ID federation with every Oracle Fusion user population — internal employees, service accounts, and external contractors — before go-live.
Cross-Cloud Analytics Rules, Not Two Separate SIEMsTwo separate SIEMs for OCI and Azure means an attacker who moves between them is never correlated. Symhas writes cross-cloud analytics rules in Sentinel — attack paths that traverse both environments detected by a single rule.
Analytics Connection Via Interconnect, Not Public InternetOracle Fusion data accessed from Azure analytics over the public internet creates a data residency and security risk. Symhas routes all Azure analytics connections to Oracle Autonomous Database via the OCI-Azure Interconnect — private throughout.
Unified Security Posture From Go-LiveOCI and Azure deployed separately and connected later produces two separate security postures that are never unified. Symhas designs the unified security posture before either cloud environment is deployed — Sentinel, Entra ID, and Defender configured for both clouds from day one.
Both Cloud Teams Certified at HandoverMulti-cloud operations require both the OCI team and the Azure team to understand the interconnect and unified monitoring. Symhas certifies both teams — OCI operations and Azure operations — before stepping back to advisory.
