Which Azure service should be recommended to ensure SSL termination for applications without separate configuration for each container?

The recommendation of Azure Front Door for ensuring SSL termination for applications without requiring separate configuration for each container is appropriate because it is designed specifically for managing and securing web traffic. Azure Front Door operates at the application layer (Layer 7) and provides capabilities such as global load balancing, SSL offloading, and application acceleration.

This service allows you to configure a single set of SSL certificates and handles the encryption and decryption of traffic at the edge, meaning that you do not have to configure SSL for each individual container or service running behind it. This simplifies management and enhances the security posture of applications by providing centralized SSL handling.

Additionally, Azure Front Door includes other features such as URL-based routing, health monitoring, and automatic failover, which further assist in managing web applications effectively across multiple regions and enhance performance. In scenarios involving microservices architectures or distributed applications, the capability to manage SSL termination centrally through Azure Front Door can significantly reduce administrative overhead and ensure consistent security practices across all components.
