Horizontal scaling

Horizontal scaling refers to the process of adding more machines or servers to a system to handle increased demand, rather than upgrading existing hardware (known as vertical scaling). Picture a restaurant: instead of making a single kitchen larger, you open more kitchen locations to serve more customers simultaneously. This method allows for better resource management and flexibility, as you can easily scale up or down based on needs. It’s commonly used in cloud computing and web services, where multiple servers work together to support applications and data efficiently.
