Amazon Elastic Compute Cloud (EC2) offers several types of load balancers to distribute incoming traffic across multiple instances. These load balancers cater to various use cases and traffic management requirements. As of my last knowledge update in September 2021, here are the main types of load balancers available in EC2:

-
Application Load Balancer (ALB):
- Layer: Operates at Layer 7 (Application layer) of the OSI model.
- Use Case: Ideal for routing HTTP/HTTPS traffic. It can route requests based on content, such as URL, host, or path, making it suitable for applications like web servers, microservices, and container-based applications.
-
Network Load Balancer (NLB):
- Layer: Operates at Layer 4 (Transport layer) of the OSI model.
- Use Case: Designed for handling TCP/UDP traffic. It’s used when you need high performance, low latency, and extreme reliability, such as for gaming applications, IoT, and financial applications.
