LambdaQ

A simple RabbitMQ based lambda like service which creates new queues for each arbritary function and auto-scales workers based on execution time.

• Simple for developers. Just define and deploy functions to the api without providing another other than the language name and function.

• Fault tolerance and load distribution to worker pools powered by RabbitMQ

• Out of the box simple scaling - worker pools increase and shrink in size based on response time allowing users to target particular response times.

• Can be extended to support RabbitMQ compatable technologies, hence it can be extended for many complex use cases by utilizing existing libraries.

• Most of the infrastructure is quite language agnostic. With the addition of new templating and parsing it can support many more programming languages.

Usage

To deploy a function submit a POST request at domain/submit with the request body in the form of {"language": "ruby", "function": "{YOUR CODE HERE}"}
