Description: Horizontal scaling, also known as horizontal scaling, refers to the practice of adding more machines or instances to a system to distribute the workload more efficiently. Unlike vertical scaling, which involves increasing the capacity of a single machine (such as adding more memory or processing power), horizontal scaling allows multiple instances to work in parallel, which can significantly improve system availability and resilience. This approach is especially relevant in cloud environments, where resources can be dynamically provisioned and deprovisioned based on demand. Horizontal scaling not only helps manage traffic spikes but also facilitates fault recovery, as if one instance fails, the others can continue to operate. Additionally, it allows for greater flexibility in resource management, as organizations can scale up or down according to their specific needs. In summary, horizontal scaling is a key strategy in distributed system architecture and in the implementation of cloud solutions, enabling businesses to quickly adapt to fluctuations in workload and optimize the performance of their applications.
