Segmentation: Use VNets for workload separation. Subnets for different applications (web, database, API). Security: Apply NSGs for traffic filtering. Regional Architecture: Implement Availability Zones for high availability. Scalability: Design for automated scaling and modular structures.
Security Solutions and Standards
Azure Firewall: Centralized access management. Integrates with Azure Sentinel. Network Security Groups: Control traffic via IP, port, and protocol for subnets and VMs. Azure Private Link: Secure access via private endpoints, isolated from the public internet. Compliance Standards: ISO27001 and NIS² for documented security policies.
Network Connectivity: On-Premises Integration
VPN Gateway: Cost-effective secured connections with limited bandwidth. ExpressRoute: Dedicated connection with high bandwidth and no internet dependency. Scalability: Dynamic scaling with Azure Virtual WAN and modular extensions.
Key Metrics to Monitor
Performance: Check bandwidth and latency for both VPN and ExpressRoute. Usage: Analyze traffic patterns with Azure Monitor.
Hybrid Network Infrastructure
Architecture Components: On-Premises Datacenter linked via VPN Gateway or ExpressRoute. Firewalls: Local security segmentation and Azure integration. Security Mechanisms: Use Private Link for secure traffic; monitor via Azure Monitor.
Regional Network Infrastructure
Regions: Select nearest Azure region to minimize latency; use multiple for redundancy. Availability Zones: Protect against datacenter-level failures. Documentation: Keep security and network topology updated.
Best Practices
Monitoring: Utilize Azure Monitor and Log Analytics for insights. Updates: Regularly revise policies per ISO27001 and NIS² standards.
Example Architecture
Connectivity: On-Premises VPN Gateway ↔ Azure VPN Gateway. Redundancy:Primary and Secondary Regions configured. Security:Azure Firewall and NSGs filter traffic.
Connections Overview
Use VPN for secure connections or ExpressRoute for dedicated bandwidth.
Prioritize security through AZs and NSGs.
