Java Load Balancing Algorithms Guide

There are several methods to implement common load balancing algorithms in Java.

1. Round Robin algorithm: Create a list to store server nodes and use a counter to keep track of the current selected node position. When a request comes in, choose the next node based on the counter and update the counter position. This method achieves a simple round-robin load balancing.
2. Random algorithm: Generate a random number using Java’s Random class, and then select a server node based on the generated random number. This enables load balancing algorithm based on random selection.
3. Weighted Round Robin algorithm: Each server node is assigned a weight value in addition to the basic round-robin algorithm, determining the probability of each node being selected based on the weight value. This allows for dynamic load balancing based on server node performance.
4. Consistent Hashing algorithm: It utilizes a hash ring to store server nodes and selects the corresponding server node based on the hash value of the request. This enables a dynamic load balancing algorithm that allows for the addition and removal of server nodes.

You can choose the appropriate load balancing algorithm based on specific requirements and implement the corresponding logic in Java to achieve load balancing functionality.
