Certificates for CDNs typically come in two flavors: Server Certificates and Client Certificates. In this answer, I'll provide you with an overview of Server Certificate Details.

Server Certificate Details

Explanation

A Server Certificate is issued by a SSL certificate authority (CA) for use with content distribution networks (CDNs) such as Cloudflare, Akamai, Amazon CloudFront, and more. Server Certificates are used to encrypt and authenticate traffic between a browser client and a CDNs edge server.

Key Facts

1. Server Certificates are created for applications that have specific requirements, such as high security, compliance with industry regulations, or high availability.
2. There are multiple CAs that offer SSL certificate services, including Let's Encrypt, Symantec, GeoTrust, and more.
3. A Server Certificate consists of six common components:
   • Key
   • Certificate
   • Issuer
   • Subject (Common Name)
   • Expiration (Date)
   • Version

Requirements

1. Server Certificates are usually generated and validated using OpenSSL or similar software on your system.
2. The Common Name of a Server Certificate must match the domain name of your CDN-supported application.
3. Server Certificates have an expiration period of several years and may be renewed automatically by the CA or manually by your system administrator.

Use Cases

1. Security and Encryption: Server Certificates help maintain security and provide privacy to users by encrypting their data between the browser and server.
2. PCI DSS Compliance: PCI DSS (Payment Card Industry Data Security Standard) compliance requires companies to use SSL-based encryption for secure data transmission. Server Certificates facilitate PCI DSS compliance.
3. High Availability and Scalability: CDNs typically cache content in their edge servers to improve performance for users. Server Certificates enable CDNs to improve system security while also handling high loads and ensuring data consistency.

Recommendation

To handle the security requirements of your distributed application, you're recommended to choose a Server SSL Certificate from a reputable SSL certificate authority, such as Let's Encrypt or DigiCert.
