Azure Application Gateway as a Web Traffic Load Balancer
Many load-balancing solutions operate on Layer 4 in the OSI model. This means that they cannot make any decisions based on HTTP, which carries information relating to the URL or headers. With Azure Application Gateway, you can extend your current architecture with a service that offers features such as Web Application Firewall (WAF), static IPs, and zone redundancy.
By going through this chapter, you will learn another way of load balancing requests. In the previous chapter, we learned about a global load balancer – Azure Front Door. Azure Application Gateway can be used as either a separate solution or another element of your architecture that is connected to your applications in a tighter way.
The following topics will be covered in this chapter:
- Azure Application Gateway features
- Configuring routing
- Integrating with web applications
- URL rewriting and redirects
