Global real time network

Provide a global real-time network that "solves the problems of large-scale IoT connectivity in the wild, enabling IoT providers to focus on their core businesses."

PubNub argues that the IoT space is held back by two major obstacles: a lack of reliable communications and security issues.

First, while reliable bi-directional signalling for IoT devices is easy in the lab, trying to achieve this in the wild becomes a huge problem, putting at risk the overall success of the deployment. It is very difficult to guarantee device connectivity through corporate and home networks, cell towers, firewalls and variable-speed wireless networks.

Second, security is a huge concern. Hackers have successfully attacked numerous highly protected corporate networks. How does an individual connected device stand a chance?

o hurdle over the first obstacle (poor M2M communications), PubNub has built and deployed a global real-time network running in 14 data centres globally. Customers connect their devices to PubNub with a single line of code, and then they can send and receive data with 0.25-second guaranteed delivery latency. PubNub also solves the issue of device status by providing real-time updates about every device's status (online/offline, etc.) across millions of devices.

PubNub says that it connects over 100 million devices monthly and processes an average of 50,000 transactions per second -- peaking at over 3 million transactions per second -- through its global network. Because PubNub replicates all data across all data centres, PubNub can provide 99.999% SLA uptime guarantees (i.e. less than 6 seconds of downtime per month).

To tackle the security issue, PubNub boosts device security in three ways: 1) access control for data streams, 2) closing open ports and limiting the ability to communicate to devices without any network ports being open on the Internet (a common attack vector for hackers) and 3) securing all communications with multiple data encryption standards like AES and SSL.
