Introduction

The Serverless Runtime is a Python-based service designed to execute offloaded functions within the COGNIT ecosystem. When a device uses the device-runtime to offload a task, the Serverless Runtime is the component responsible for receiving, executing, and returning the result of that task.

It exposes a REST API to handle function execution requests, allowing developers to offload computation from resource-constrained devices.

High-Level Functionality

Function Execution: Receives serialized functions via a REST API endpoint, executes them in an isolated environment, and returns the result.
Service Integration: Provides pre-configured clients for interacting with essential services, such as MinIO for object storage, directly from within the offloaded function.
Stateless and Scalable: Designed to be stateless, making it easy to deploy and scale across multiple nodes in an edge-cloud continuum.
Centralized Logging: Integrates with a standardized logger, allowing logs generated by the offloaded function to be captured and viewed alongside the runtime's own logs.
