Illustrative example
Authentication & authorization
- Managed identities: Microsoft Entra ID authentication without credentials in code
- Azure Key Vault: Secure storage for secrets, certificates, and keys
- Shared access signatures: Time-limited, scoped access to Service Bus/storage
- OAuth 2.0 & OpenID Connect: Standard protocols for API authentication
- Certificate-based auth: Mutual TLS for service-to-service communication
Network security
- Private endpoints: Access Azure services over private IP addresses
- VNet integration: Logic Apps Standard and APIM in your VNet
- IP filtering: Restrict access to known IP ranges
- Service endpoints: Secure Azure-to-Azure connectivity
- Application Gateway + WAF: Web application firewall for APIs
Monitoring & observability
- Azure Monitor: Centralized logging and metrics for all integration services
- Application Insights: Distributed tracing across Logic Apps and APIs
- Log Analytics: KQL queries for deep troubleshooting
- Service health: Azure platform health and planned maintenance
- Alerts & action groups: Proactive notifications and automated remediation
- Logic Apps run history: Detailed execution logs with input/output tracking
On-premises data gateway
Secure bridge between on-premises data and cloud services. Data gateway enables:
- Hybrid connectivity: Access on-premises SQL, file shares, SAP
- Security: Encrypted connections without VPN or firewall changes
- High availability: Gateway clustering for redundancy
- Monitoring: Gateway health and performance metrics
DevOps & deployment
Infrastructure as code
- ARM templates: Azure Resource Manager templates for resource deployment
