By automatically starting or stopping VCS via the TWCC CLI, the system can be ensured to run on demand, avoiding unnecessary billing expenses and effectively reducing costs. At the same time, this method improves operational efficiency, reduces the time and manpower costs of manual operations, and ensures more accurate resource management. Through automated scheduling, users can flexibly control the VCS status, ensuring the system starts when needed and shuts down when idle, achieving more efficient use of cloud resources.

When a Virtual Compute Service (VCS) instance is created, a 100 GB system disk is provided as the default storage space. In practice, storing data on the system disk can lead to management difficulties. Therefore, users typically choose to mount virtual disks as data drives. This article provides a reference for using Rclone to mount Cloud Object Storage (COS) as a storage option.

The UI provides a monthly overview of VCS resource usage, including CPU and memory, and offers monitoring graph downloads. The API allows users to obtain long-term usage data for analysis or report generation, retrieve the key, project, and VCS ID step-by-step, and use the GetCPUUtilizationByServer API to obtain CPU usage every 5 minutes. Other APIs, such as GetDiskUtilizationByServer, can retrieve disk, memory, and network usage.
