Improve End User Experience with Redundant DNS Services

The Domain Name System (DNS) is a distributed internet database that maps human-readable names to IP addresses, enabling users to reach the correct destination when entering a URL. DNS availability and performance are central to the user experience. A contemporary webpage can involve dozens of DNS lookups. For complex web pages, DNS resolution can comprise as much as 29% of initial page load time. Many businesses rely solely on in-house DNS solutions that don’t deliver global reach, availability, or performance. Creating a highly scalable, reliable, and efficient DNS service requires time, money, and know-how.

Relying on a single DNS solution with a small footprint is inherently risky and inefficient. Concerns include the following: availability constraints, security vulnerabilities, and performance constraints. You can improve the performance, security, and reliability of your DNS infrastructure by adding a managed DNS service to your IT environment. Best-of-breed managed DNS service providers have the global DNS infrastructure and deep DNS expertise to ensure success. Adding a redundant DNS service provides resiliency at the DNS layer.

Some advantages of adding a redundant DNS service include global scalability, high availability, strong security, rapid record propagation, and DNS expertise and support. A well-managed DNS service is a great way to protect and extend your previous DNS infrastructure investments. You can evaluate, pilot, and implement a redundant service without introducing risk or disrupting your current DNS infrastructure.

Distributed DNS networks can be implemented using two distinct standard-based IP addressing schemes. Unicast addressing delivers unpredictable results and less consistent performance as the DNS request may be answered by any Point of Presence (PoP) which can potentially increase latency. Anycast addressing optimizes DNS performance, enabling consistent user experiences across the globe as the DNS request is answered by the closest Point of Presence (PoP) for the fastest possible DNS performance. Anycast offers a wide variety of advantages in DNS.

There are a variety of ways to add a redundant DNS service to your existing DNS infrastructure. The Traditional Primary-Secondary Option, Hidden Master-Secondary Option, and Primary-Primary Option. Go to a service provider that lives and breathes DNS. Best-in-class managed DNS providers have worldwide DNS infrastructure, experience, and resources to ensure your success.

DNS speed and reliability are fundamental to the performance of your web-based applications, services, and data, and are essential to your business. You can improve end-user experiences and boost business results by adding a redundant managed DNS service to your IT infrastructure.
