What Are Inbound Bandwidth and Outbound Bandwidth?

Inbound bandwidth: refers to the bandwidth consumed when data is transferred from the Internet to HUAWEI CLOUD. For example, resources are downloaded from the Internet to ECSs in the cloud.

Outbound bandwidth: refers to the bandwidth consumed when data is transferred from HUAWEI CLOUD to the Internet. For example, the ECSs in the cloud provide services accessible from the Internet and external users download resources from the ECSs.
