AWS Application Load Balancer
AWS Application Load Balancer is a managed load-balancing service that routes HTTP and HTTPS application traffic across targets using application-level request attributes.
Amazon Web Services in Action, Third Edition: An in-depth guide to AWS
An application load balancer is an AWS load-balancing service that routes HTTP and HTTPS traffic based on application-level request attributes.
- How it is used
- Distributes HTTP and HTTPS requests across application backends while separating users from individual server addresses.
- How deep it goes
- Works through load balancer, listener, target group, health checks, and CloudFormation configuration; does not detail ALB internals.
- Examples
- Shows load-balanced WordPress servers, CloudFormation resources for an Auto Scaling group, and an ECS/Fargate note-taking application.
- What you can do after
- Build it from scratch with CloudFormation by configuring an ALB, HTTP listener, health-checked target group, and Auto Scaling group.
Machine Learning System Design
AWS Application Load Balancer is a managed service that distributes application traffic across multiple targets using application-level routing.
- How it is used
- Deploys real-time inference behind EC2 servers when high load and low latency make serverless scaling difficult.
- How deep it goes
- Connects load balancing to stateless workers, guaranteed capacity, scaling, and spot replacement, but defers hardware sizing to experiments.
- Examples
- Uses EC2 inference servers behind an AWS Application Load Balancer for PhotoStock’s high-load, low-latency queries.
- What you can do after
- Operate/configure real-time inference with EC2 workers behind an AWS Application Load Balancer while planning capacity and replacement.
