Azure Application Gateway is an advance type of load-balancer. Where an Azure Load-balancer routes traffic on the transport layer (OSI Layer 4 | TCP + UDP) the Application Gateway is a way more advanced load-balancer. It can route based on URL as well on path’s. On top of that it can do much more, like SSL offloading, autoscaling, redirection, multiple site hosting and the most import of all, it can include a web application firewall (WAF)
With all the features that the Azure application gateway provides, we should be able to setup multiple websites listening on different ports and url’s behind one Azure Application Gateway with just one external IP address.
With this guide you should be able to setup an application gateway with multiple site hostname match and http to https redirect. In this manual we will be using Atlassian Jira and Confluence as an example.
So what are we going to setup:
- Deploy Azure application gateway
- Configure 2 external URL’s (jira.2azure.nl and confluence.2azure.nl)
- We will redirect port 80 to 443 for both websites
- Jira will be listening on port 8080 internally (Default port)
- Confluence will be listening on port 8090 internally (Default port)
For this guide the VNET, subnets and the virtual machine hosting both websites have already been deployed. During this guide we will not deploy a Web Application Firewall, I will tell more about that in upcoming blog article.Continue reading “Deploy Azure Application Gateway with http to https redirect”
