How do load balancers work?

See more about Convesio’s Load Balancers and how we leverage this technology for huge Woocommerce sites and other that have high traffic and require better availability: https://convesio.com/features/wordpress-load-balancer/

A load balancer is like a traffic cop for the internet. It helps make sure that when people are using a website or application, everything runs smoothly and quickly. It does this by sending the traffic to different servers (computers that store and run websites) so that no one server gets too overwhelmed. If a server is not working well, the load balancer will send the traffic to a different server instead. This helps make sure that everyone can use the website or application without any problems.

Load balancers are used to distribute incoming network traffic across multiple servers or resources in order to optimize resource utilization, maximize throughput, minimize response time, and avoid overload.

Here’s how they work:

  1. When a client sends a request to the load balancer, it routes the request to one of the servers or resources in its pool using a scheduling algorithm.
  2. The scheduling algorithm determines which server or resource should receive the request based on factors such as the number of current connections, the server’s processing ability, and the server’s overall health.
  3. The load balancer then routes the request to the selected server or resource, which processes the request and returns a response to the client.
  4. The load balancer can also monitor the health of the servers or resources in its pool and remove any that are not responding or are not able to handle requests.

There are several types of load balancers, including hardware load balancers, software load balancers, and cloud load balancers. They can be used in a variety of applications, including web servers, databases, and applications.
