If you're ready to start building, head straight to Installation or Adding Lug to a Function.
What does Lug do?
Lug is a tool that allows you to move the execution of specific Python functions to different environments on each call. This means that instead of deploying a function permanently to a specific environment (e.g. your local computer or a cloud-based server), you can choose where you want to run the function at the time of execution. This flexibility allows you to optimize your resource consumption and cost for the needs of the specific function.
Lug is particularly useful for computational science, where researchers and scientists often have programs that are challenging to install and run. Lug automatically detects and packages pip-installed dependencies and local modules, and you can even attach a sidecar Docker image for the command-line programs that need their own image – making it simple to debug and scale your code.
What isn't Lug good at (yet)?
- Short-running functions – there's a startup time (1-5 minutes) for each cloud run
- Hosting for reference databases / models / etc (try Toolchest for that if you're in bio)
- It's one line of code
- You don't need to statically define your dependencies
- Lug is open source (Apache 2.0)
