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
  • ChatEngine: open and extensible chat framework for building and powering 1:1 and group chat

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