Choosing IPLC cloud server as the infrastructure can ensure low latency and high stability of cross-border links. However, although IPLC cloud server itself can greatly improve the quality of cross-border access, the service capacity of a single node is still limited in the face of globally distributed user groups or large-scale concurrent access. At this time, combined with CDN (content distribution network) deployment, it will effectively magnify the advantages of IPLC cloud server and achieve a better access experience.
Why do you need to deploy CDN on IPLC cloud server?
The advantages of IPLC cloud server mainly lie in low latency, low packet loss rate, high security and strong stability of cross-border links. However, IPLC cloud server also has limitations. The physical node location is fixed and cannot cover global users nearby. The bandwidth and anti-DDoS capabilities of a single node are limited.
Deploying CDN can make up for these shortcomings well, cache static resources to CDN edge nodes around the world, enable users to access nearby, and significantly shorten loading time. Mainstream CDN provides basic DDoS protection functions to improve website security. And CDN will share a large number of requests and reduce the load of IPLC cloud server.
To deploy CDN acceleration on an IPLC cloud server, the following preparations need to be made:
1. Confirm the source site architecture, ensure that the business website, application or interface on the IPLC cloud server can normally respond to the back-to-source request from the CDN node, and configure the access log to facilitate later troubleshooting.
2. Configure domain name resolution to ensure that the business domain name has been filed (such as for users in mainland China) and supports custom DNS resolution to facilitate subsequent access to the CDN service provider's CNAME record.
3. Determine the CDN acceleration scope and clarify which business resources need to go through CDN, such as static resources (images, CSS, JS, audio and video files, etc.), API interfaces (some CDNs support dynamic and static separation or dynamic acceleration), whole-site acceleration (select on demand), etc.
4. Select a suitable CDN service provider. The selection can refer to the following standards: such as global node coverage, support for IPLC cloud server source sites, security protection capabilities, bandwidth prices and billing models, whether HTTPS and HTTP/3 are supported, etc.
Operation steps for deploying CDN on IPLC cloud server
Step 1: Create an accelerated domain name on CDN platform
Log in to CDN management console, select "Add website" or "Create accelerated domain name", enter the domain name you bound to IPLC cloud server, CDN platform will automatically scan existing DNS records, you need to keep the source site related records, delete useless or duplicate items. Then configure the source site address, fill in the public IP of IPLC cloud server as the source site. If you use a domestic CDN service provider, you also need to select the acceleration area (global/mainland China/Hong Kong, Macao and Taiwan/overseas) and configure the back-to-source protocol (HTTP/HTTPS).
Step 2: Configure cache rules
Set a reasonable cache strategy in CDN console, and cache static resources for a longer time (such as 1 day-30 days). Dynamic pages are set to not cache or cache for a short time. It is recommended to configure advanced options such as dynamic and static separation and URL parameter ignoring according to business needs.
Step 3: Set protection and optimization
1. Enable basic DDoS protection. Most CDN service providers provide protection by default, and can upgrade advanced protection packages as needed.
2. Enable HTTPS acceleration, apply for SSL certificate for CDN accelerated domain name, support own certificate or CDN platform free certificate, and realize full-link encryption.
3. Enable Gzip/Brotli compression to reduce resource transmission volume and speed up loading.
4. Configure access control, set IP blacklist and whitelist, UA restriction, regional access restriction, etc. to improve the security of source site.
Step 4: Switch DNS to CDN
In domain name DNS management, point the A record or CNAME record of the business domain name to the acceleration address provided by the CDN platform. After the DNS switch is completed, the user request is received by the CDN node and returned to the IPLC cloud server.
Step 5: Verify the effect
Verify whether the CDN deployment is effective by the following methods:
1. Use the curl -I command to check whether there is a CDN logo in the response header
2. Check the source station log to confirm that the request has been returned to the source by the CDN node
3. Test the access speed changes of global nodes through webmaster tools, Ping, and Traceroute
Precautions during CDN deployment
1. The bandwidth configuration of the source station should be reasonable. Although CDN can share a large amount of traffic, insufficient bandwidth of the source station may still become a bottleneck when high concurrency is returned to the source.
2. Set up the whitelist of return IPs. It is recommended to only allow CDN platform node IP return access in the IPLC cloud server firewall to prevent attacks bypassing CDN.
3. Cache configuration needs to be combined with business characteristics. Static resources should be cached as long as possible, and dynamic resources should be careful to prevent data delays.
4. HTTPS full-link encryption ensures that the return link from CDN to the source station is also encrypted to ensure data security.
5. Monitoring and alarming, configure traffic monitoring and alarming of CDN and source stations to detect abnormal access or attack behaviors in time.
Deploying CDN on IPLC cloud server is an effective solution to improve the access speed and security of cross-border websites, foreign trade e-commerce, video streaming, game acceleration and other services. IPLC cloud server provides high-quality dedicated line back to the source guarantee, while CDN distributes content and resists attacks worldwide. The combination of the two complements each other's advantages and realizes the best practice of global business development.
