    Resource Expected amount
    Outbound data transfer
    • Daily peak bandwidth: about 1 Gbit/s
    • Outbound data transfer: 3.16 TB per day, 95 TB per month, 570 TB per six months, and 1,140 TB per year
    HTTPS requests for static content
    • Daily maximum number of queries per second (QPS): about 3,000
    • Number of requests: about 78 million per day, 2.33 billion per month, and 27.96 billion per year
    OSS storage capacity

    The OSS storage capacity is based on the cache hit ratios of Alibaba Cloud CDN. The higher the cache hit ratios, the lower the fees charged by OSS.

    For example, the byte hit ratio and request hit ratio of Alibaba Cloud CDN are both 90%. In this case, 10% of the network traffic and requests are redirected to the origin server, which is an OSS bucket. OSS charges fees for the data transfer generated during back-to-origin routing. For more information, see OSS Pricing.
