DNS BIND and CDN

What You’ll Learn:
• DNS Fundamentals: Understand the hierarchical structure of the domain namespace—an "inverted tree" starting from the root (.) down to Top-Level Domains like .com and .org.
• The 4 Critical Servers: We explain the specific roles of the DNS Recursor, Root Nameserver, TLD Nameserver, and Authoritative Nameserver in every web request.
• Implementing BIND: A look at the Internet's most popular DNS implementation. We cover primary (master) versus slave (secondary) servers, zone transfers, and essential configuration files like named.conf.
• Advanced Routing with Anycast: Discover how Anycast DNS uses BGP to route your queries to the topologically nearest server instance for maximum speed and DDoS resiliency.
• Global Server Load Balancing (GSLB): Learn how to achieve multi-site resilience by directing traffic based on real-time server health and user proximity.
• The Power of CDNs: See how replicating content at the Internet's edge minimizes the geographic distance between data and the end-user.
