Round Robin Load balancing explained in detail

Are you looking for a way to make your business more efficient and flexible? Then, Round Robin Load balancing is the perfect solution! This technique helps to distribute requests evenly across a cluster of servers or other resources, ensuring that each server is used roughly the same number of times. 

Meaning of Round Robin Load balancing

Round Robin is a Load balancing technique of evenly distributing requests across a cluster of servers or other resources. It works by making a list of available resources. Then it uses an algorithm to assign one server at a time to each request, rotating through the list of available resources until all have been used before starting again at the top, hence the “Round Robin” name. This ensures that each server is used roughly the same number of times so that all resources are utilized as evenly as possible. This is beneficial as it allows for greater flexibility and scalability as more tasks can be distributed, and any single resource is less likely to become overloaded. It also improves efficiency by providing continuity and ensuring no single resource handles more than its share.

Round-Robin DNS – How does it work?

Is Round Robin Load balancing advantageous?

Round Robin Load balancing is a great choice for many businesses as it provides several key benefits:

  1. It ensures even distribution of requests and tasks, which in turn guarantees a better utilization of resources, as every resource will receive roughly the same number of requests.
  2. It allows for more efficient scaling, as resources can be added to the pool easily, allowing for more requests to be handled without any single resource becoming overwhelmed.
  3. It provides greater flexibility, as users can easily tailor the algorithm to their needs, giving a great degree of control over how their resources are utilized.

What kinds of Load balancing algorithms are there?

We can define 2 different types of Load balancing. First, Dynamic Load balancing algorithms prioritize sending traffic to servers with the least open connections. In contrast, Static algorithms such as weighted round robin and IP hash distribute traffic via DNS records or IP addresses. Let’s now explore them in more detail.


  • Least Connection: Prioritizes sending traffic to servers with the fewest active connections 
  • Weighted Least Connection: Assigns custom weights to each server to determine how much traffic to send 
  • Weighted Response Time: Prioritize servers based on their average response time 
  •  Resource-Based: Distributes load based on available resources of each server  


  • Round Robin: Rotates traffic between servers via DNS records 
  • Weighted Round Robin: Assigns weights to each server, allowing some to receive more traffic than others 
  • IP Hash: Utilizes the source and destination IP addresses of incoming requests to assign traffic to servers


Round Robin Load balancing is great for businesses looking to increase efficiency and scalability. By ensuring that all requests are evenly distributed across all available resources, companies can rest assured knowing that they are making the most of their resources. So, it’s good to give it a chance and try it!
