LambdaFn

An open source, self-hosted service to run AWS Lambda Functions on your own hardware.

This project is to learn more about Golang, FAAS and cloud computing

• Installation Instructions - INSTALL.md

Project

• This project is to try creating a service which can work like AWS Lambda / Google AppEngine
• All code executions happen on your own hardware. Docker is used to manage containers that run code
• It would lack the trigger integrations that AWS Provides with its lambda functions
• It would allow user to build a lambda function via AWS Cloudformation templates (drop in replacement)
• It would allow users to execute the lambda and send events via an HTTP REST API

Working

Goals

The service should allow executing the following:

• Binary on the server running the service
• Code written as Lambda zip running inside container on the server
• Container to be executed on the server (or kubernetes cluster)

ToDo List

• Implement Code Execution on server as a service
• Implement Function as a service inside container
• Integrate HTTP REST API to allow creation of lambda functions and executing them
• Create client binary to allow creating and invoking lambda functions
• Reformat existing code to use storage package. Create S3 backed local source code cache.
• Dockerize the whole service (currently looks out of scope due to the nature of storage service)
• Implement Hot & Cold Containers with timeouts
• Implement Container Running as a service

Future Goals

• Implement and Integrate an HTTP Proxy (like API Gateway) to allow functions to respond to REST calls
• Implement methods to monitor resource utilisation by functions
• Implement Authentication / Authorization on the HTTP REST API
