Application Performance

Senior IT leaders that care about application performance know that DNS is a powerful lever that can dramatically improve reliability, speed, and uptime.


Even a short period of downtime can translate to a significant cost for your business. And a more serious problem, like critical infrastructure failure can take your application down for hours or even days with costs upwards of $1 million or more. For enterprises that deliver their products primarily through digital channels, brand damage coupled with potential revenue loss can make that number climb even higher. On the other hand, there is a substantial evidence that points to high performing applications with fast page load times attracting and retaining more users and having better conversion rates.

Today, the expectation of fast, reliable, and responsive delivery has become the norm for every online application. And since it matters to your customers, and it should matter to you.

Improve application performance by getting closer to your customers

Because DNS is typically the first point of contact between a customer and an application, it can can extend the plane of control to the extreme edge of the Internet. Developers can use DNS to enact failover, disaster recovery, load-shedding, load-balancing and other traffic management functions at points much closer to the end user. By doing so, they can separate the traffic orchestration layer from the core application itself, thereby bolstering resiliency. This capability can dramatically reduce downtime while dramatically improving performance metrics like latency and time to first byte.

Intelligent DNS can dramatically improve application performance

NS1's Intelligent DNS and Traffic Management Platform leverages something you already use, DNS, and turns that into a powerful lever that application developers can use to improve performance. With powerful and easy to use Filter Chain technology, it’s a simple point and click affair to configure complex, tailor-made routing algorithms specific to your application needs. 

Automate load shedding and load balancing to help shift traffic from a server that is under stress or down to one that is performing well. Use NS1's geo-capabilities, including EDNS-CLIENT-SUBNET, to optimize traffic management based on accurate country, region, or even lat/long information. Or take things to the next level and use Pulsar, NS1's advanced traffic routing engine. Pulsar leverages real-time data from your users and applications to enable hyper-granular, automated, and optimized traffic routing decisions.
