Question

How do you design a multi threaded concurrent server? What are server clusters?

Answer 1

Multi-threaded concurrent servers are designed to handle multiple client connections simultaneously using threads. Server clusters are a group of multiple servers working together to provide high availability, fault tolerance, and scalability.

Step-by-step explanation:

Designing a multi-threaded concurrent server involves creating a server that can handle multiple client connections simultaneously using threads. This allows the server to execute tasks concurrently, improving its performance and responsiveness.

An example of designing a multi-threaded concurrent server in Java:

1. Create a ServerSocket to listen for client connections.
2. When a client connects, create a new thread to handle the client's request.
3. Within the thread, read the client's input, process it, and send a response back.
4. Continue listening for more client connections.

A server cluster is a group of multiple servers working together to provide high availability, fault tolerance, and scalability. It allows distributing the workload across the servers in the cluster, improving performance and ensuring that the service remains available even if individual servers fail.

Each server in a cluster performs a specific task or provides a particular service. They communicate and synchronize with each other to ensure that tasks are efficiently distributed and that the overall system operates smoothly.
