As cyberattacks and user expectations continue to grow, adding CDN (content delivery network) defenses to servers has become one of the key steps to improve performance and ensure security. Using a CDN on a Singapore server can not only speed up the transmission of website content, but also effectively resist various network attacks. This article will detail how to add CDN defense to Singapore servers to achieve the perfect combination of performance and security.

　　CDN is a distributed network architecture that achieves faster and more reliable content transmission by storing content on servers around the world. The basic principle of a CDN is to direct user requests to the nearest server, thereby reducing latency and improving website performance.

　　Benefits of CDN defense:

　　1. Improve website performance. Through CDN, users can obtain website content more quickly, improve website loading speed, and improve user experience.

　　2. Strengthen security. CDN not only provides protection against common attacks, but also effectively mitigates DDoS attacks and improves server security.

　　3. Global coverage. The distributed architecture of CDN enables the website to provide consistent performance globally and meet the access needs of global users.

　　Steps to add CDN defense to Singapore server:

　　1. Choose a CDN service provider:

　　​Choose a trustworthy CDN service provider. Some common CDN providers include Akamai, Cloudflare, Amazon CloudFront, Fastly, and others. Make sure the CDN provider you choose has good network coverage in the Singapore area.

　　2. Create a CDN account and configure a domain name:

　　​Sign up for an account on the CDN service provider’s website and add your domain name. Configure your domain name according to the provider's guidelines to ensure that the CDN can properly cache and distribute your static resources.

　　3. Modify DNS settings:

　　Point the domain name’s DNS resolution settings to the DNS server provided by the CDN provider. This usually involves modifying the domain name registrar's DNS records. In the CDN console, you will find the corresponding DNS settings information.

　　4. Enable SSL/TLS:

　　Enable SSL/TLS in the CDN provider's console to provide an encrypted connection. This helps protect data as it travels between the client and the CDN.

　　5. Set up defense performance:

　　Most CDN providers provide basic DDoS (distributed denial of service attack) defense capabilities. Make sure these defense mechanisms are enabled to protect your server from DDoS attacks.

　　6. Optimize cache settings:

　　Adjust CDN cache settings to ensure static resources are fully cached. This helps reduce load on the server and improves page loading speeds.

　　7. Enable Web Application Firewall (WAF):

　　Some CDN providers offer web application firewall services. Enabling a WAF can help prevent common web attacks such as SQL injection, cross-site scripting (XSS), and more.

　　8. Performance optimization:

　　​ Take advantage of your CDN provider’s performance optimization features, such as automatic image optimization, compression, and resource merging, to improve page load speeds.

　　9. Monitoring and analysis:

　　Use your CDN provider’s monitoring and analysis tools to monitor traffic and performance in real time. This helps identify problems and make adjustments promptly.

　　10. Disaster recovery configuration:

　　Consider using multiple CDN nodes for added redundancy. In the CDN console, multiple nodes can be configured to ensure high availability of the server.

　　11. Test and adjust:

　　After switching to a CDN, conduct thorough testing. Make sure the site still functions properly under the CDN, resolve any issues that may arise, and make adjustments as needed.

　　Through the above steps, you can strengthen the security and performance of the Singapore server, reduce the burden on the server, and improve the user experience.
