Description: Capacity adjustment refers to the modification of computing resource capacity to optimize the performance of applications and services in cloud environments. This process is fundamental in cloud computing, where the demand for resources can vary significantly over short periods. Autoscaling, a key technique within capacity adjustment, allows organizations to automatically increase or decrease the amount of allocated resources, such as servers, storage, and bandwidth, based on current needs. This not only improves operational efficiency but also helps control costs, as companies only pay for the resources they actually use. Capacity adjustment relies on performance and load metrics, enabling a quick response to changes in demand. Additionally, this approach contributes to application resilience, ensuring they remain available even during traffic spikes. In summary, capacity adjustment is an essential strategy for maximizing performance and efficiency in resource management in the cloud, dynamically adapting to the changing needs of businesses.
