Load Balacing and routing

Load Balancer

• Manage traffic to direct the traffic to corresponding backend pool by using ip-address and port within the same region

Application Gateway

• Manage traffic to direct the traffic to corresponding backend pool by using ip-address and path within the same region

• rate limiting by web application firewall

Traffic Manager

• A DNS-based traffic load balancer. This service allows you to distribute traffic to your public facing applications across the global Azure regions

• Route the traffic by performance, weighting and priority

Front door

• Front Door (classic) works at Layer 7 (HTTP/HTTPS layer) using anycast protocol with split TCP and Microsoft's global network to improve global connectivity. Based on your routing method you can ensure that Front Door (classic) will route your client requests to the fastest and most available application backend.

• The combination of traffic manager and application gateway

Azure Firewall

• To hidden the vm ip address of vms behind the firewall

• Set the outbound rule and inbound rule to secure the traffic

Virtual WAN

• To group the networkings of different virtual network together instead of peering between networks one by one in order to faciliate the following

• Branch connectivity (via connectivity automation from Virtual WAN Partner devices such as SD-WAN or VPN CPE).

• Site-to-site VPN connectivity.

• Remote user VPN connectivity (point-to-site).

• Private connectivity (ExpressRoute).

• Intra-cloud connectivity (transitive connectivity for virtual networks).

• VPN ExpressRoute inter-connectivity.

• Routing, Azure Firewall, and encryption for private connectivity.

Express Route

• Directly connect to virtual network directly instead of via internet
