Scale-out architecture

Scale-out architecture is a way of building systems where multiple computers or servers work together to handle data and tasks. Instead of relying on a single, powerful machine, you add more servers to increase capacity and performance. This approach allows the system to grow easily as demand increases, providing better reliability and flexibility. It's like adding more lanes to a highway to reduce traffic congestion—more servers distribute the workload, ensuring smoother operation without upgrading a single machine.
