NS1 Launches Pulsar 2.0 to Meet Performance Needs for Modern Hybrid Infrastructure

Pulsar enables organizations with multi-CDN and cloud infrastructures to dynamically route traffic based on performance conditions and business logic.

NEW YORK – April 11, 2018 – NS1, today announced the launch of Pulsar 2.0, a cloud-based routing engine that uses real user monitoring data to enable intelligent traffic management decisions for optimal application performance and maximum uptime.

There is a clear relationship between how well an application or website performs for the end user and whether that user becomes and remains a customer. When it comes to modern applications, the rise of SaaS and market demand for rich content delivery, even milliseconds of latency – or, worse, downtime – can dramatically impact user experiences and loyalty, brand reputation, conversions, and, ultimately, the bottom line.

In order to diversify, improve user experiences, gain flexibility and reduce costs, enterprises are increasingly adopting hybrid infrastructures that incorporate modern technologies, such as cloud environments and multiple content delivery networks (CDNs). As their infrastructure becomes more diverse and distributed, companies need a means of intelligently routing traffic that is simple to implement and manage. This is especially true for organizations with global presence as well as those with high content delivery needs. With Pulsar, NS1 is the only managed DNS provider that gives enterprises the ability to easily route traffic to multiple CDNs and cloud facilities based on availability, performance and business logic.

“Internet performance is highly variable and can be unreliable, particularly in countries with fragmented connectivity markets. Congestion, broken links, demand surges and server outages happen all the time, affecting user experience and costing both time and money,” said NS1 co-founder and CEO Kris Beevers. “Pulsar is the only integrated solution that detects and dynamically adjusts for conditions on the internet, at CDNs and in cloud services. Its real-time performance optimizations add to the bottom line.”

Unlike traditional solutions that rely exclusively on static traffic routing techniques such as geotargeting, the NS1 platform incorporates both static and real-time data, enabling engineers to control and optimize which CDNs and cloud facilities users are directed to when they request online content or application services. With the addition of Pulsar, enterprises can incorporate real-time performance and availability telemetry from dozens of CDNs and public clouds operating in every internet market to optimize routing decisions instantly.

Pulsar 2.0 features granular, single-pane-of-glass visibility into CDN and cloud performance, while delivering advanced analytic capabilities that empower IT teams to best leverage infrastructure for the highest business value.

In addition to billions of real-time, real users’ measurements, customers can feed their own measurements to Pulsar for intelligent routing of users to application-specific private or public cloud facilities. Pulsar’s “biasing” controls allow engineers to enable business-based thresholds that balance performance against cost.

Pulsar has immediate impact on application performance. It is the easiest and most efficient way to implement RUM steering because it is the only solution that combines RUM steering and Managed DNS capabilities. Without this unified approach, user requests would first need to query the DNS provider, followed by the RUM steering provider, and finally the optimal CDN or data center. The fact that NS1's Pulsar RUM steering engine is fully integrated with NS1's DNS eliminates this extra dependency and lookup, saving time, reducing complexity and improving reliability. NS1's Linked Record technology further allows customers to reduce this process to just a single lookup, which can save an average of 100ms in just the DNS resolution process.

“DNS is vital to the performance and resiliency of diverse environments like hybrid and multi-cloud initiatives, and static traffic routing controls aren’t designed to interact with and orchestrate always-on, constantly changing conditions in the modern application delivery environment,” said Eric Hanselman, Chief Analyst at 451 Research. “Real-time integration of performance metrics is needed and the approach that the NS1 platform with Pulsar offers could allow enterprises to more effectively optimize application performance in multi-CDN and multi-cloud environments. Together they present greater challenges and demand higher levels of flexibility and customization.”
