Integrating a CDN with cloud services enhances performance, scalability, and security for websites and apps. Prerequisites include a cloud account, domain name, DNS access, and a CDN provider. Steps involve choosing a compatible CDN, configuring your cloud hosting (AWS, Google Cloud, Azure), connecting the domain via CNAME records, enabling SSL/TLS, and optimizing caching. Best practices suggest using multiple CDNs, edge caching, WAF, and regularly reviewing configurations. Common issues like caching problems or SSL errors can be resolved by adjusting TTL or checking certificates. Monitoring performance ensures efficiency and reliability for global users.
