How-To / Steps / Framework Application

Implementing Azure Front Door involves several key steps:

1. Prerequisites: You'll need an active Azure subscription, a registered domain name, and backend application(s) deployed in Azure or other cloud providers.
2. Create a Front Door Profile: In the Azure portal, create a new Front Door profile. This profile acts as a container for all the configurations related to your application's traffic management.
3. Configure Frontend Hosts: Define the domain names or subdomains that users will use to access your application. You can either use a custom domain or an Azure-provided domain.
4. Add Backend Pools: Specify the backend servers (e.g., web servers, application servers) that will handle user requests. Backend pools can include servers in different Azure regions or even other cloud providers.
5. Define Routing Rules: Create routing rules to determine how traffic is directed to the backend servers. These rules can be based on criteria such as the requested URL, the user's geographic location, or the type of device.
6. Configure Web Application Firewall (WAF): Enable the WAF to protect your application from common web vulnerabilities. Customize WAF rules and policies to meet your specific security requirements.
7. Enable Caching: Configure caching rules to store frequently accessed content at the edge locations. This reduces the load on your backend servers and improves loading times.
8. SSL/TLS Configuration: Configure SSL/TLS certificates for secure HTTPS connections. You can either use certificates managed by Azure or import your own certificates.
9. Monitor and Optimize: Use Azure Monitor and other tools to monitor the performance of your application and Front Door configuration. Continuously optimize your settings based on the performance data.
