How does Akamai manage DNS traffic?

Akamai manages DNS traffic through a globally distributed DNS infrastructure. This architecture allows Akamai to provide low-latency responses to DNS queries by routing requests to the nearest DNS server based on the user's location. This distribution is crucial for improving performance and reliability, as it mitigates single points of failure and reduces the time it takes for queries to be resolved.

The global infrastructure also enables Akamai to intelligently handle traffic loads, balancing requests among various servers to ensure that no single server is overwhelmed. This design supports dynamic scaling, meaning that as demand fluctuates, the DNS infrastructure can adapt accordingly.

In contrast to centralized or manual approaches, the distributed model enhances redundancy and availability, ensuring that DNS services remain resilient against outages or surges in traffic. Centralizing all DNS requests in one location would introduce latency and potential points of failure, while redirecting requests randomly would not guarantee optimal routing or performance. Similarly, employing manual traffic management would be inefficient and prone to human error, particularly in a network as extensive as Akamai's.
