Examples
Scenario
Alice wants to accelerate content delivery for a small-sized community website. The information about the website is:
Website type: small-sized community website. Website content: images, text, and on-demand videos.
Acceleration region: Chinese mainland.
Other services: Image and video files are stored in an Object Storage Service (OSS) bucket. HTTPS secure acceleration is used to encrypt data transmission.
Resources expected to be consumed:
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.
