Which service is designed for automated scaling of applications on Alibaba Cloud?

Alibaba Cloud Auto Scaling is specifically designed to manage the scaling of applications automatically based on the defined policies and real-time resource usage metrics. This service enables organizations to maintain optimal application performance by automatically adjusting the number of compute resources—such as ECS instances—during peak and off-peak times.

By using this service, businesses can ensure that their applications can handle varying loads without manual intervention, helping to optimize costs and resource utilization. Auto Scaling monitors application performance and adjusts the available resources to meet demand, ensuring that applications remain responsive and efficient.

In contrast, the other options do not focus directly on automated scaling. Resource Management is primarily about managing resources efficiently rather than scaling them. Load Testing evaluates application performance under expected loads, not automating resource scaling. Similarly, the Performance Analyzer is more about analyzing and improving performance rather than managing scaling processes. Thus, Auto Scaling is the most relevant service for automated application scaling on Alibaba Cloud.
