Before You Start

Before using CDN, read this section to learn about acceleration domain names, origin servers, CDN billing, security settings, and how to verify the acceleration effect. This helps you quickly enable and use CDN.

Domain Names and Origin Servers

Before using CDN, prepare a domain name for acceleration and an origin server (service server) based on the domain name admission conditions, content moderation requirements, and domain name description in the Notes and Constraints.

Billing

Understanding CDN billing details helps you select a proper billing option when enabling CDN, thereby reducing costs. Huawei Cloud CDN charges you for basic services (mandatory) and value-added services (optional).

The basic service fee is calculated based on traffic or bandwidth generated when users access CDN points of presence (PoPs).
The value-added service fee is calculated based on the number of whole site acceleration requests.

Unless otherwise specified:

For WSA domain names (with Service Type set to Whole site), the basic service fee is calculated based on the larger value between uplink and downlink traffic and bandwidth at edge PoPs.
For CDN domain names (with Service Type not set to Whole site), the basic service fee is calculated based on the downlink traffic and bandwidth at CDN edge PoPs.

**Table 1** Billing options
Billing Item	Billed By	Description
Basic service fee	Traffic	This option is suitable for domain names with highly fluctuating traffic patterns, average bandwidth utilization below 30% throughout the day, and occasional bandwidth peaks. You can buy traffic packages of appropriate specifications to save money. For details, see Prepaid Traffic Packages.
	Peak bandwidth	This option is suitable for domain names with stable traffic patterns and average bandwidth utilization above 30% throughout the day. You need to submit a service ticket to request this billing option.
	95th percentile bandwidth	These two options are suitable if your service traffic is heavy and your monthly expenditure exceeds $15,000 USD. Contact your account manager and request these billing options.
	Average daily peak bandwidth
Value-added service fee	Whole site acceleration request	If you use whole site acceleration, you will be charged by the number of requests.

Resource Types and Service Types

CDN caches content to speed up content delivery. It caches static resources on CDN PoPs so that users can get the resources from the nearest PoP. Whole site acceleration speeds up the transmission of dynamic and pseudo-static resources through optimized network routing.

**Table 2** Resource types
Resource Type	Description
Static	The same file is obtained for each request. Examples: images, videos, files (HTML, CSS, and JS) on websites, software installation packages, APK files, and compressed packages
Dynamic	Different files are obtained for each request. Examples: files (ASP, JSP, PHP, PERL, and CGI) on websites, APIs, and database interaction requests
Pseudo-static	Pseudo-static resources, such as HTML files, appear to be static on websites, but are actually processed using dynamic scripts such as ASP. Pseudo-static resources are essentially dynamic and are processed as dynamic content.

CDN provides four service types. Select a service type based on the resource characteristics of your website to achieve better acceleration.

**Table 3** Service types
Service Type	Scenario
Website acceleration	Web portals, e-commerce platforms, news apps, and user generated content (UGC)-focused apps
File download acceleration	Download clients, game clients, app stores, and websites that provide download services based on HTTP or HTTPS
On-demand service acceleration	On-demand video/audio services, such as online education websites, video sharing websites, TV VOD platforms, and music and video apps
Whole site acceleration	Websites that consist of both dynamic and static content, especially those with numerous ASP, JSP, or PHP requests

Service Area

CDN provides three service areas. Select one based on the distribution of your end users to improve user experience.

Service Area	Acceleration Effect	Scenario
Chinese mainland	All user requests are scheduled to PoPs in the Chinese mainland.	Users are mainly located in the Chinese mainland.
Outside Chinese mainland	All user requests are scheduled to PoPs outside the Chinese mainland.	Users are mainly located outside the Chinese mainland.
Global	User requests are scheduled to the optimal CDN PoP nearby.	Users are distributed around the world.

Outside Chinese mainland indicates countries and regions other than the Chinese mainland, including Hong Kong (China), Macao (China), and Taiwan (China).
The service area of a domain name has nothing to do with the origin location. You can choose the service area that suits your services best.

(Optional) Security

If your website has high security requirements, configure security settings to prevent malicious traffic or attacks.

Function	Description
HTTPS certificate	Enable HTTPS acceleration to encrypt requests between clients and CDN PoPs, securing data transmission.
Access control	Identify and filter visitors using referer validation, IP address access control lists (ACLs), token authentication, and User-Agent ACLs, restrict access sources, and prevent malicious traffic and attacks.
Interconnection with WAF	Associate Huawei Cloud CDN with Web Application Firewall (WAF) to accelerate delivery of website resources and defend against web attacks.

Acceleration Effect Evaluation

You can use a third-party dialing test tool to test the response speed of websites. The test method is as follows:

Test the response speed of accessing a resource after CDN acceleration is used.
Test the response speed of accessing the same resource directly from the origin server.
Compare the preceding two data.

Important notes:

If you test the access to an uncached resource, CDN needs to pull it from the origin server. Accessing it through CDN will be more time-consuming. Use a cached resource for test.
This solution is used for qualitative analysis on the acceleration effect. If you require professional evaluation, contact professional analysis platforms (such as Tingyun and Bonree).
