Code Explanation:
The program starts by defining a Task class representing the tasks that will be load balanced across different servers in the cluster. The Task contains an execute method that prints out the current thread’s name as a placeholder for where the actual task logic would reside.
The LoadBalancer interface declares methods for adding servers and retrieving the next server to distribute tasks. The RoundRobinLoadBalancer class is an implementation of this interface, using a round-robin strategy to distribute the tasks evenly across available servers. It holds a list of servers and an index to keep track of the current server.
Server class mimics a server in the cluster. Each server has a task queue and a name. The addTask method allows tasks to be added to the server’s queue, and the start method starts a new thread to simulate task processing, where it sequentially executes tasks from its queue.
The DynamicLoadBalancer class binds everything together. It includes a LoadBalancer to distribute tasks and methods to add servers and submit tasks to the cluster. The main method initializes the dynamic load balancer, creates servers, and then submits multiple tasks to the cluster, which are then load balanced across the available servers.
The main logic of the program revolves around the LoadBalancer which distributes tasks, while each Server processes tasks asynchronously. This simulates a dynamic cluster environment where tasks are balanced across different servers, ensuring no single server is overwhelmed. The round-robin approach helps in equally distributing the load without complex algorithms.
