AWS EC2 Application Load Balancer

The AWS EC2 Application Load Balancer (ALB) is a highly scalable and flexible load balancing service designed to distribute incoming HTTP and HTTPS traffic across multiple targets, such as EC2 instances, containers, and IP addresses, within one or more Availability Zones. It operates at the application layer (Layer 7 of the OSI model), allowing advanced routing based on content such as URL paths, host headers, and HTTP headers. ALB supports features like SSL termination, WebSocket support, and integration with AWS services like Auto Scaling and ECS, making it ideal for modern web applications and microservices architectures.
