Getting Started with Network - Manage Internet Facing Load Balancer - in Java

Azure Network sample for managing Internet facing load balancers -

High-level ...

  • Create an Internet facing load balancer that receives network traffic on port 80 & 443 and sends load-balanced traffic to two virtual machines

  • Create NAT rules for SSH and TELNET access to virtual machines behind the load balancer

  • Create health probes

Details ...

Create an Internet facing load balancer with ...

  • A frontend public IP address
  • Two backend address pools which contain network interfaces for the virtual machines to receive HTTP and HTTPS network traffic from the load balancer
  • Two load balancing rules for HTTP and HTTPS to map public ports on the load balancer to ports in the backend address pool
  • Two probes which contain HTTP and HTTPS health probes used to check availability of virtual machines in the backend address pool
  • Two inbound NAT rules which contain rules that map a public port on the load balancer to a port for a specific virtual machine in the backend address pool
  • this provides direct VM connectivity for SSH to port 22 and TELNET to port 23

Create two network interfaces in the frontend subnet ...

  • And associate network interfaces to backend pools and NAT rules

Create two virtual machines in the frontend subnet ...

  • And assign network interfaces

Update an existing load balancer, configure TCP idle timeout Create another load balancer Remove an existing load balancer
