What are the inbound and outbound bandwidths of a cloud server instance?

Inbound and outbound bandwidth refer to the data transfer rates into and out of a cloud server instance, respectively.

• Inbound bandwidth is the rate at which data is received by the server from external sources (e.g., users downloading files, API requests).
• Outbound bandwidth is the rate at which data is sent from the server to external destinations (e.g., serving web pages, uploading data to a database).

For example, if a cloud server has 1 Gbps inbound bandwidth and 500 Mbps outbound bandwidth, it can receive data at up to 1 Gbps (e.g., handling many simultaneous user requests) but can only send data at up to 500 Mbps (e.g., streaming video or delivering content).

In Tencent Cloud, you can choose bandwidth configurations based on your needs. For high-performance workloads, Tencent Cloud CVM (Cloud Virtual Machine) offers flexible bandwidth options, including pay-as-you-go or bandwidth packages, ensuring optimal cost and performance. For example, a web server handling heavy traffic can be configured with higher outbound bandwidth to ensure smooth content delivery.
