Frequently Asked Questions
How do PubNub Functions differ from external services like AWS Lambda?
PubNub Functions offers a unique advantage by operating directly within the PubNub network, providing real-time data transformation, enrichment, and event handling with minimal latency. Unlike external services like AWS Lambda, which requires sending traffic out of the PubNub network for code execution and then retrieving responses, PubNub Functions execute in the same environment as the events they process. This ensures faster, more efficient performance, ideal for low-latency, real-time applications such as live chats, gaming, or IoT.
Additionally, PubNub Functions significantly reduces system and architectural complexity. Simplify your tech stack and focus on building your application without the need to integrate or manage external services. PubNub Functions also leverages a distributed, edge-based architecture, enabling data to be processed closer to the source of events. This edge processing capability not only reduces latency further but also enhances reliability and scalability, making it a powerful choice for real-time use cases.
