# 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**

![LambdaFn in Action](assets/img.png)

- [Installation Instructions - INSTALL.md](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

![Working Diagram](assets/initialDiagram.png)

## 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

- [x] Implement Code Execution on server as a service

- [x] Implement Function as a service inside container

- [x] Integrate HTTP REST API to allow creation of lambda functions and executing them

- [x] 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
