Ekko

Ekko is an open-source framework that provides realtime infrastructure and in-transit message processing for web applications. It lets developers deploy scalable realtime infrastructure to AWS with a CLI tool, and process messages as they move through the system using modular serverless functions.

• Ekko Functions: serverless, reusable message transformations applied in transit
• Message routing based on channel-function associations
• Automatic horizontal scaling, with the cloud infrastructure complexity abstracted away behind automated deployment

Deploying the whole thing takes a single command from the Ekko CLI:
