Today’s World

Dynamic, Distributed Applications

• Many locations for the same content

• Services and infrastructure are dynamically provisioned

• Scale – billions of users • Speed – very low end user

tolerance for delay• Explosion of applications• Infrastructure as code

Delivery Gap

• Traditional DNS: Minimal support for application delivery optimization.

Deployment Gap

• Traditional DNS: Minimal DevOpssupport – no native orchestration or APIs for record instantiation and service discovery.

Why do all this with DNS?

•Pervasive: part of every application, used by every client

•Lightweight: no application / architecture changes, no hardware / software

The Traditional DNS Paradigm

Traditional DNS

• One server end point• Simple transaction• Static content

• Proprietary extensions to legacy solution.

• Bound by simple geographic routing and availability monitoring (if available)

TopologyHealthLoadTraffic

• Modern DNS traffic management should use live metrics.

• Infrastructure telemetry is an untapped resource that provides a heartbeat, status and other key data.

Leveraging Infrastructure Telemetry

LatencyThroughputReachability

• Modern DNS should leverage key metrics around network performance

• Latency, throughput, and reachability are easily extrapolated from 3rd party monitoring or native eyeball networks.

What Makes NS1 Different From Every Other DNS

• Meta Data: Attach static and real time information to each answer in a DNS record

• Filter Chain: Use the meta data to apply traffic management logic to steer users to the optimal end point

SLIDE 16

• KPI Driven Traffic Management• Latency Optimized• Bandwidth Optimized• Cost Optimized• Policy Based

Filter Chain™ Technology

“NS1 is a critical component of our application architecture. We’ve seen amazing performance from the platform, enabling us to deliver a flawless experience to our customers’ end users”

- Julien Lemoine, CTOAlgolia “
