What is FaaS and Serverless

FaaS (Function as a Service) is a way how you can execute your code in the cloud while paying only for execution time (and memory consumption) without the need of maintaining your infrastructure (read more here).

Providers like AWS Lambda, Azure Functions, ... already support languages like Java, Python or JavaScript so that you can build complex Microservice alike web applications without the worry of the infrastructure overhead.

Applications built with combination of cloud solutions like FaaS (AWS Lambda, Azure Functions,...), cloud databases (DynamoDB, Firebase,...), cloud authentication solutions (Auth0, AWS cognito,...) and other cloud solutions is what we call Serverless (read more here)

FaaS products like AWS Lambda are to "compute" similar what AWS S3 is to "storage". It's the new era of web application Architecture and Ruby community wants to be in the front line !

What is the point of this Website ?

The heart of every application is computing power. Serverless is not different. That's why it's so critical to have Ruby available for FaaS.

Goal of this website is to prove to FaaS providers there is a large demand from Ruby community in building applications this way with Ruby language

All FaaS providers are driven by market value when choosing what programming language will they support next. If more developers will bother them with requesting Ruby then more likely it is it will get available.

Existing FaaS providers and FaaS solutions for Ruby

AWS Lambda

IBM Cloud Function

IBM Cloud Function is using OpenWhisk for its lambda infrastructure, which supports Ruby. IBM Cloud Function documentation on how to create Ruby actions

FaaStRuby

FaaStRuby is an experimental simple serverless platform for Ruby developers.

Functions are triggered via their HTTPS endpoint. They will receive the request body, query parameters, headers and they can have an optional execution context. You can set custom response headers and status code.

OpenWhisk

Serverless Ruby with Docker and Apache OpenWhisk

Kubeless

Kubeless is a Serverless framework based on Kubernetes (container orchestration) and you are able to run your own FaaS provider that supports Ruby.

As you / your team is the one maintaining this FaaS provider you need to pay for uptime of VMs supporting those Docker containers (it's not like with AWS Lambda "pay for what you use based on 100ms of usage")

This may be a great solution for companies that don't want to lock their infrastructure to particular provider and are not afraid to maintain the entire FaaS infrastructure themself.

Iron Functions

Iron Functions is an open source serverless computing platform by Iron.io with built in Ruby language support.

You can run & maintain this platform yourself or you can use provider Iron.io to run this for you. They have a monthly pricing for alocated computing power.

OpenFaaS

OpenFaaS runs on Docker Swarm, Nomad or Kubernetes. You can run it on the cloud as well as on your laptop or a bare metal cluster. (Develpers will have to maintain the FaaS infrastructure)

They have a language template for Ruby so you can create Ruby functions including support for gems.

Serverless Framework with Ruby

Serverless.com is framework for building serverless applications.

It seems like they have a section on Ruby but I've never tried it out (can anyone confirm how well it works in this discussion ?)

I can only recommend it on JS projects.

Jets Ruby Serverless Framework

Jets is a framework that allows you to create serverless applications with a beautiful language: Ruby. Jets includes everything required to build an application and deploy it to AWS Lambda. Jets offers native-like Lambda performance for Ruby and powerful tools to help you develop in the serverless world. While at the same time, it allows you to use other languages like Node and Python for certain use cases. Jets makes serverless accessible to everyone.

Hacky solutions for other FaaS providers

AWS Lambda

I recommend you to watch James Thompson talk "Serverless" Ruby on AWS Lambda but in principle there are two "hacky" ways how to try Ruby on AWS Lambda:

Run JRuby

AWS Lambda supports Java therefore you can run JRuby on Java Lambda.

Execute Ruby binary from JS/Py AWS Lambda

You need to download Traveling Ruby (which is binary executable of Ruby v 2.2.2) place it and all the dependencies (lib, gems,...) to a zip file and then you configure JavaScript or Python AWS Lambda to run this binary executable of Ruby.

So it's JavaScript / Python executing Ruby, therefore really hacky solution and not recommended for prod.
