Performance scaling refers to the ability of a system or application to handle increased workloads effectively. This can involve adding more resources, such as servers or processing power, to maintain or improve performance as demand grows. It ensures that users experience consistent speed and reliability, even during peak usage times. There are two main types of performance scaling: vertical and horizontal. Vertical scaling involves upgrading existing hardware, while horizontal scaling adds more machines to distribute the load. Both methods aim to enhance the overall efficiency and responsiveness of systems, making them better equipped to manage varying levels of demand.
