What is Cloudflare?

Cloudflare is a global network of servers that sits between your website's hosting and your visitors. It acts as a reverse proxy, caching your website's content and delivering it to users from the closest server location. This reduces latency, speeds up page load times, and enhances overall website performance.

Core Functionality:

• CDN (Content Delivery Network): Distributes your website's content across a global network of servers.
• Web Application Firewall (WAF): Protects your website from various online threats, such as DDoS attacks and bot traffic.
• DNS (Domain Name System) Services: Provides fast and reliable DNS resolution.
• SSL/TLS Encryption: Secures the connection between your website and visitors.

Benefits of Cloudflare

Cloudflare offers numerous advantages for website owners:

• Improved Website Speed: Faster loading times due to content caching and optimized delivery.
• Enhanced Security: Protection against cyber threats, including DDoS attacks and malicious bots.
• Increased Reliability: High availability and uptime with a globally distributed network.
• Simplified Management: User-friendly interface and easy-to-use tools for managing your website's performance and security.
• Cost-Effective Solutions: Free and paid plans to suit different needs and budgets.

How Cloudflare Works

Cloudflare's architecture is built on a distributed network of data centers strategically located worldwide. When a user visits your website, their request is routed to the nearest Cloudflare server. This server then: — Bf2042 Kill Steal: My Tank Kill Got Stolen!

1. Retrieves Cached Content: If the requested content is cached, it's delivered directly from the Cloudflare server, reducing the load on your origin server.
2. Fetches Fresh Content: If the content is not cached, the Cloudflare server fetches it from your origin server and caches it for future requests.
3. Applies Security Measures: Cloudflare's WAF filters malicious traffic and protects your website from attacks.

This process significantly improves website performance and security.

Step-by-Step Breakdown:

1. Website Visitors Request: A user enters your website's address (URL) in their browser.
2. DNS Resolution: The user's browser queries the DNS to find the IP address of your website.
3. Cloudflare Interception: If you're using Cloudflare, the DNS directs the request to a Cloudflare server.
4. Content Delivery: Cloudflare serves the requested content to the user, either from its cache or by fetching it from your origin server.
