Review Questions

• How does Cloudflare improve website performance and security through its CDN services?
  • Cloudflare improves website performance by using its CDN to cache content on servers located closer to end users. This reduces latency as the time taken to retrieve data from distant servers is minimized. In terms of security, Cloudflare acts as a reverse proxy that filters out malicious traffic, thereby protecting websites from threats like DDoS attacks while ensuring that legitimate traffic reaches the site without interruption.
• Discuss the role of Cloudflare in mitigating DDoS attacks and how this impacts website availability.
  • Cloudflare plays a crucial role in mitigating DDoS attacks by absorbing and dispersing excessive traffic aimed at overwhelming a website. By leveraging its vast network of servers, Cloudflare can identify and block malicious traffic before it reaches the targeted site. This ensures that legitimate users can still access the website even during an attack, greatly improving overall availability and reliability for businesses relying on online presence.
• Evaluate the benefits of using Cloudflare’s SSL certificates for businesses and how this contributes to user trust.
  • Using Cloudflare’s SSL certificates provides businesses with significant benefits by encrypting sensitive data exchanged between users and their websites. This encryption not only protects user information from potential interception but also enhances user trust in the brand. Websites with SSL certificates display 'https' in their URLs, signaling to users that their data is secure, which can lead to higher conversion rates and increased customer loyalty as users feel safer interacting with those sites.
