PubNub Data Stream Network

PubNub Data Stream Network

The secret sauce that makes it all work. A global network infrastructure powering APIs for low-latency realtime messaging to anywhere on Earth.

PubNub DSN connects 15 globally redundant points of presence into a single network capable of handling hundreds of millions of simultaneous device connections and relaying trillions of messages.

PubNub APIs Powered By the DSN

Realtime Messaging

A serverless environment to execute functions on the edge, transforming, enriching, and filtering messages as they route through the PubNub DSN.

How It Works

How It Works

Think of PubNub as a Content Delivery Network (CDN), but for the streaming web. While a CDN is designed to serve static content (i.e. ‘data at rest’), a Data Stream Network (DSN) is optimized for serving dynamic content (i.e. ‘data in motion’), in realtime.


PubNub can be used to quickly push small messages to one or more devices (smartphones, browsers, microcontrollers, tablets, etc.) – essentially, just about any device that can make a TCP/IP connection to the internet – as well as back again, for bidirectional communication between devices.


And PubNub knows that security, data ownership, and access control are critical to any realtime application – which is why we have built the entire Data Stream Network around these core tenets.

We Take Security Seriously

PubNub DSN provides rich authorization, authentication, encryption, and legislative
security encircling every level, from network to user.


Encryption
Encryption

TLS and AES256 encryption, plus support for BYOE (bring-your-own-encryption) models.

Access Control
Access Control

PubNub Access Manager delivers fine-grain access control for every device and every channel.

Authorization Schemes
Authorization Schemes

PubNub Functions support flexible authorization schemes via any OAuth and LDAP model.

Attack Prevention
Attack Prevention

No inbound open ports and instantaneous routing to different data centers to thwart regional attacks.

Legislation and Compliance
Legislation and Compliance

HIPAA Compliance, SOC 2 Compliant, Data Shield certified, and EU-only Data Storage options.

Focus On Innovation, Not Infrastructure

Hugely scalable. Super-fast. Secure. Works on everything.


  • Scale

    Low-latency realtime messaging anywhere in the world. PubNub processes 5x the data that Twitter does, and that number only continues to grow.

  • Works Everywhere

    No compatibility headaches. With over 70 SDKs, from mobile and web to embedded, PubNub works across all devices and apps, on all types of networks.

  • 99.999% SLA

    Let our 9s do the talking. Build your app with PubNub, and sleep easy at night knowing that scale, latency, data durability, and security are rock solid.
