Description: Horizontal scaling is the process of adding more machines or instances to a group to handle increased load. Unlike vertical scaling, which involves increasing the capacity of a single machine (such as adding more memory or processing power), horizontal scaling focuses on distributing the workload across multiple servers. This strategy allows organizations to manage traffic spikes and improve the availability of their services. One of the most notable features of horizontal scaling is its ability to provide redundancy; if one machine fails, the others can continue operating, minimizing downtime. Additionally, horizontal scaling is fundamental in distributed systems and cloud environments, where flexibility and responsiveness are essential. Implementing this approach can be more complex, as it requires proper network management and data synchronization between instances. However, its ability to adapt to changing load needs and its potential for cost optimization make it an attractive option for many companies looking to scale their operations efficiently and effectively.
