Classic Load Balancer (CLB)
The Classic Load Balancer is the oldest of the three types and is designed for applications that were built within the EC2-Classic network. It operates at both the application and network layers, distributing traffic across instances based on either application or network-level information.
While it provides basic load balancing capabilities, CLB lacks some of the advanced features available in the newer load balancers.
What are the 3 Types of Load Balancers in AWS?
Load balancing is a crucial aspect of ensuring high availability, scalability, and fault tolerance in cloud computing environments. Amazon Web Services (AWS) provides several types of load balancers to distribute incoming traffic across multiple targets, such as instances, containers, and IP addresses.
The three main types of load balancers in AWS are
- the Classic Load Balancer (CLB),
- the Application Load Balancer (ALB), and
- the Network Load Balancer (NLB).
