distributed systems design

Distributed systems design involves creating a collection of independent computers (or nodes) that work together as a single system. These nodes communicate over a network to share tasks, data, and resources, allowing the system to be more scalable, reliable, and efficient. Instead of relying on one powerful machine, functions are distributed across multiple machines, which can handle more load and recover quickly from failures. Proper design ensures these nodes coordinate seamlessly, maintain data consistency, and work efficiently as a unified system, enabling applications like cloud services, social media platforms, and large-scale data processing.
