What type of load balancer is most beneficial for websites and mobile applications running containers on EC2 instances?

The Application Load Balancer (ALB) is particularly well-suited for websites and mobile applications running containers on EC2 instances due to its advanced routing capabilities and support for HTTP/HTTPS traffic. ALB operates at the application layer (Layer 7 of the OSI model), allowing it to make intelligent routing decisions based on the content of the request. This is particularly useful for applications that rely on microservices architecture, which is common when using containers.

With an ALB, you can define rules to route traffic based on various parameters such as the path of the request or the hostname, enabling sophisticated URL-based routing. It also supports WebSocket and HTTP/2, making it a great choice for modern web applications that require real-time communication or better performance. Furthermore, ALB integrates seamlessly with the Amazon ECS (Elastic Container Service) and EKS (Elastic Kubernetes Service), simplifying the configuration and management of containerized applications.

This load balancer also provides features such as health checks for the individual containers, ensuring that traffic is only directed to healthy instances, which enhances the reliability and user experience of the application. The ability to handle millions of requests per second and automatically scale to meet demand without manual intervention aligns perfectly with the requirements of dynamic and rapidly changing
