  • 9. Your Infrastructure & Why You Should Pay Attention to DNS
    • Load balance between your existing infrastructure and the cloud using DNS. We call it Dynect Traffic Management.

  • 10. Dynect Traffic Management (DTM) – Take Control
    • Managed Global Server Load Balancing (GSLB)
    • DNS based, as a service
      • No hardware
      • No CAPEX
    • Distribute load to datacenters or availability zones in cloud environments
    • DTM works in conjunction with existing local load balancers and health monitoring systems

  • 12. How it Works – twitter.com is here … US West US Central US East EU Central EU West EU East Asia 1 1 1 2 2 2 3
  • 13. Monitoring and Failover
    • DTM can perform health checks against content servers and load balancers to see if traffic should be sent to that node
    • Monitoring intervals – 1 minute
    • Checks are performed from multiple datacenters to reduce false-positives
    • HTTP and HTTP (with response inspection), SMTP, and ICMP checks available
  • 14. Overcoming Browser Limitations
    • Recursive DNS servers, OSes, and browsers cache data: use extremely low TTLs and ensure fast delivery with anycast
    • High performance managed DNS (Dynect Platform) easily handles low TTLs
  • 15. Load Balancing Options
    • Externally measured availability
    • Externally measured latency
      • Real Time Traffic Management
    • Externally exposed internal metrics
      • Database load
    • Internal decisions
      • Internal monitoring, internal logic, Dynect API calls
  • 16. Best Practice for Availability and Performance
    • Multiple geographic regions
    • Each with a local load balancer
      • Enables rapid local failover for isolated, local incidents
        • Server crash, disk failure
    • Global Server Load Balancing via Dynect Traffic Management
      • Manage traffic to geographic regions
      • Enables rapid global failover for systemic incidents
        • Upstream transit, power
