What benefit does horizontal scalability provide in high-frequency small payload situations?

In high-frequency small payload situations, horizontal scalability is particularly beneficial because it enhances the ability to handle numerous simultaneous requests. This means that instead of relying on increasing the power of a single server (vertical scaling), additional servers are added to distribute the load. In scenarios where many small transactions occur, such as rapid API calls, the ability to scale out by adding more instances allows for better resource allocation and ensures that each request can be processed concurrently.

By leveraging this scalability, organizations can maintain performance during peak loads, as the incoming requests can be managed across multiple servers. This reduces the risk of any one server becoming a bottleneck, which is crucial when dealing with high transaction volumes. Thus, the implementation of horizontal scalability allows systems to remain responsive and efficient, accommodating ongoing high-frequency transactions without degradation in service.
