How is bandwidth data in cloud on-demand usage statistics calculated?

Bandwidth data in cloud on-demand usage statistics is typically calculated based on the amount of data transferred between your cloud resources (such as virtual machines, storage, or applications) and external networks (internet or other cloud services) over a specific period. It is measured in bits per second (bps) or bytes (GB, TB) and can be billed based on actual usage or predefined tiers.

Calculation Methods:

  1. Ingress (Incoming Traffic): Data transferred into your cloud resources from external sources.
  2. Egress (Outgoing Traffic): Data sent from your cloud resources to external destinations.

Some providers may exclude internal traffic (e.g., between VMs in the same region) from bandwidth charges.

Example:
If your web server hosted on the cloud serves 100 GB of data to users over the internet in a month, the egress bandwidth usage would be 100 GB. If the provider charges $0.10 per GB for egress, the cost would be $10.

For precise monitoring and optimization, Tencent Cloud offers Cloud Monitor (CM) and Bandwidth Usage Reports to track real-time traffic and historical trends. Services like Tencent Cloud CDN can also help reduce bandwidth costs by caching content closer to users.
