CDN:Guidelines for choosing resource plans

Last Updated:Sep 20, 2023

Alibaba Cloud CDN provides you with cost-effective resource plans. This topic describes how to choose and purchase resource plans.


We recommend that you choose resource plans based on the features and services that you want to use, business volume, and acceleration region.

  • You can purchase resource plans on the buy page.

  • For more information about the pricing of resource plans, see CDN Pricing.

Choose resource plans

If you want to purchase an outbound data transfer plan, select the pay-by-data-transfer metering method. If the metering method of Alibaba Cloud CDN is not pay-by-data-transfer, you can change it based on your business requirements. For more information, see Change the metering method.



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:


    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.

  2. Determine the capacity and subscription duration of the resource plans

    Select outbound data transfer plans for Alibaba Cloud CDN and DCDN based on the expected amount of data transfer of your domain name and the capacity options listed on the buy page, as described in the following table.

    Expected amount


    Subscription duration

    Benefit and drawback

    95 TB per month

    50 TB

    1 month

    This solution consumes two data transfer plans every month, which requires frequent purchases.

    570 TB per six months

    200 TB

    6 months

    This solution consumes three data transfer plans every six months, but has discounts available.

    1,140 TB per year

    1 PB

    1 year

    In this example, Alice runs a small-sized community website. The website may attract more visitors and experience fluctuations in outbound data transfer. Data transfer resources may be wasted if Alice purchases an outbound data transfer plan of one year.
