Classic Load Balancing vs Application Load Balancer
Developers should learn Classic Load Balancing when working with legacy AWS environments or applications that rely on its specific features, such as TCP/SSL load balancing or integration with EC2-Classic networks meets developers should use application load balancer when building scalable web applications, apis, or microservices on aws that require intelligent traffic routing, ssl/tls termination, or integration with serverless components. Here's our take.

Classic Load Balancing
Nice PickDevelopers should learn Classic Load Balancing when working with legacy AWS environments or applications that rely on its specific features, such as TCP/SSL load balancing or integration with EC2-Classic networks
Pros
- +It is useful for scenarios where minimal configuration and cost-effectiveness are priorities, but it lacks the advanced capabilities of newer services like Application Load Balancer (ALB) or Network Load Balancer (NLB)
- +Related to: aws-application-load-balancer, aws-network-load-balancer
Cons
- -Specific tradeoffs depend on your use case
Application Load Balancer
Developers should use Application Load Balancer when building scalable web applications, APIs, or microservices on AWS that require intelligent traffic routing, SSL/TLS termination, or integration with serverless components
Pros
- +It is particularly useful for applications with dynamic scaling needs, such as those using containers (ECS/EKS) or serverless functions (Lambda), where ALB can route requests based on content like URL paths or host headers
- +Related to: aws-ec2, aws-lambda
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Classic Load Balancing if: You want it is useful for scenarios where minimal configuration and cost-effectiveness are priorities, but it lacks the advanced capabilities of newer services like application load balancer (alb) or network load balancer (nlb) and can live with specific tradeoffs depend on your use case.
Use Application Load Balancer if: You prioritize it is particularly useful for applications with dynamic scaling needs, such as those using containers (ecs/eks) or serverless functions (lambda), where alb can route requests based on content like url paths or host headers over what Classic Load Balancing offers.
