8 Load Balancing Techniques Every Business Organization should Know

There are different types of load balancing algorithms that IT teams choose counting on the distribution of load i.e. whether it’s a load on the network layer or application layer.

The selection of the choice of backend servers to forward the traffic is predicated on the global server load balancing algorithms used.

The algorithms take two aspects of the servers into consideration i) Server health and ii) Predefined conditions.

Few general load balancing algorithms used frequently by IT teams include 

  1. Round Robin Algorithm

The round-robin (RR) algorithm could also be a circular distribution of requests to enterprise servers during a sequence. There are two types of Round Robin algorithms – Weighted Round Robin and Dynamic Round Robin algorithms.

Used mainly for a cluster of various servers, in the weighted round-robin, each server is assigned a weighted counting on its composition.

Based on the reassigned efficiency the load is distributed during a cyclical procedure. Dynamic round-robin is wont to forward requests to associated servers supported real-time calculation of assigned server weights. 

  1. Least connections

By taking into consideration the amount of active and current connections to every application instance, the ‘Least Connections’ load-balancing algorithm distributes the load by choosing the server with the smallest amount number of active transactions (connections). 

  1. Weighted least connections

In weighted least connections the load distribution supported both the factors – the amount of current and active connections to every server and therefore the relative capacity of the server. 

  1. Source IP hash

In a source IP Hash, load balancing a server is chosen supported a singular hash key. The Hash keys are generated by taking into account the source and destination of the request. Based on the generated hash key, servers are allocated to clients. 

  1. URL hash

URL hashing may be a load balancing technique utilized in load-balanced servers to serve to request URL means to serve content unique per server. It improves the capacity of backend caches by avoiding duplicate caches. 

  1. The least response time

In the least reaction time algorithm, the backend server with the smallest amount number of active connections. Therefore the least average reaction time is chosen. Using this algorithm IT ensures quick reaction time for end clients 

  1. The least bandwidth method

In the least bandwidth method, backend servers are selected to support the server’s bandwidth consumption. The server consuming the least bandwidth is chosen (measured in Mbps).

Similar to the least bandwidth method is that the little amount packets method. Here the server transmitting the least packets is selected by the load balancer. 

  1. The custom load method

In the custom load method, the backend servers are chosen to support the load. CPU usage and response time of the server are taken into consideration to calculate the server load.

In enterprises, IT teams use this algorithm usually to efficiently establish resource utilization. This algorithm is suitable when traffic is constant and predictable, just in case of uneven and sudden traffic changes it’s not so suitable.
