How Does A Load Balancer Work?
A load balancer operates by following the steps below:
- A certain port and protocol, such as HTTP, HTTPS, TCP, or UDP, are used by the load balancer to receive inbound traffic from clients. We refer to this as a listener.
- Using a routing algorithm—such as round robin, least connections, or source IP hash—the load balancer chooses a target from a list of registered targets. We refer to this as a target group.
- The load balancer passes the request to the chosen target after connecting to it on a particular port and protocol. After answering the request, the target returns the response to the load balancer.
- The response is returned to the client by the load balancer.
What Are AWS Load Balancer Types ?
Managing and allocating incoming network traffic is a critical component in the dynamic realm of cloud computing that helps to guarantee high availability and dependability for online applications. Load balancers from Amazon Web Services (AWS) offer a reliable solution. It’s critical to comprehend load balancers if you’re new to using AWS. The practice of load balancing divides incoming traffic among several servers or applications to maximize scalability, availability, and performance. AWS provides many load balancer types to meet various circumstances and demands. We will explore the idea of AWS load balancers in this post, going over terms, detailed procedures, diagrams, and examples to help you understand the basics.
