Azure Overall Network Architecture

Planning a microservices architecture on Microsoft Azure? This post dives into the essential network components that will ensure your application is secure, scalable, and highly available.

Azure’s Networking Powerhouse for Microservices:

  • Azure Virtual Network (VNet):

The foundation for isolating and segmenting your network within Azure. VNets allow secure communication between microservices and, if needed, with the internet.

  • Azure Load Balancer or Azure Application Gateway:

Distribute traffic evenly across your services or instances.

  • Load Balancer:

Operates at layer 4 (TCP/UDP), perfect for general traffic distribution.

  • Application Gateway:

A layer 7 (HTTP/HTTPS) option offering advanced features like SSL termination, WAF (Web Application Firewall), and URL-based routing – ideal for HTTP-based microservices.

  • Network Security Groups (NSGs):

Enforce security rules at the subnet or network interface level, safeguarding your microservices from unauthorized traffic.

  • Azure DNS:

Provides name resolution using Microsoft’s infrastructure, crucial for service discovery within your microservices architecture.
