Description: Scalability testing is a set of evaluations designed to determine a system’s ability to handle an increase or decrease in workload. These tests are crucial to ensure that applications and services can adapt to variations in demand without compromising performance. Scalability can be vertical, where resources are added to a single node, or horizontal, where more nodes are added to the system. Scalability testing helps identify bottlenecks, assess response times, and measure performance under different load conditions. This is especially relevant in cloud environments, where resources can be dynamically provisioned and deprovisioned. By conducting these tests, developers can ensure that their applications not only perform well under optimal conditions but also maintain acceptable performance during traffic spikes or high-demand situations. Implementing scalability testing is an essential component of the software development lifecycle, as it helps prevent performance issues that could affect user experience and the organization’s reputation.
