The best features for Microsoft Azure Application Gateway basically protect your application and provide security-related features and also divert the traffic to different instances of your application. I have used URL-based routing, which helps manage traffic efficiency. It is a bit hard to manage in the long run, but it does provide value. I have used the gateway's Web Application Firewall feature, which enhances security as it is the first entry point to your network from the outside world. It helps protect against unwanted requests and other threats that can be configured. Regarding the integration with Azure Active Directory, it helps with authentication processes to configure all the users or the groups. The monitoring capabilities on Azure provide insight into application performance and potential threats because monitoring comes with many products. On Azure, you have Azure Monitor itself to help you monitor the application by collecting data. You have Application Insights and the logging workspace on Azure. By combining these three, you can implement monitoring solutions on Azure applications. Auto-scaling is important because it helps in resource management for customers. Scaling is one of the key features of moving to cloud for any customer. During peak times or special events, such as retail site promotions, user load increases significantly. To address this, based on the number of incoming requests or server capacities such as CPU and memory, you can automatically identify these peak scenarios and configure either scaling up or down automatically based on certain parameters.
