Technologies specific to this challenge

The PubNub Data Stream Network 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. The Data Stream Network architecture was built as a network – not as a single PoP “cloud” solution – allowing PubNub to deliver unmatched speed, reliability, and scalability.

Serverless compute for building and scaling realtime applications. * Program the Network - build features in a fraction of the time with code that runs inside the network. *Serverless Architecture deployment and scaling all handled for you. *Integrated Key/Value Store reduces latency. *Effortless Scaling Run app logic in the network instead. * Zero Added Latency Fewer hops
