PubNub Key Concepts

PubNub’s globally distributed network infrastructure powers three core services from which all other features build upon:

  • Publish/Subscribe: this is the messaging pattern for how to stream data in realtime across the PubNub network for realtime updates and IoT
  • PubNub Functions: this enables you to run code directly inside the PubNub network, which executes on your data as it is being streamed between senders and receivers

From here, we will explore all the other PubNub tools available to you for building awesome realtime applications!
