Pedestal
The Pedestal Server-side Libraries
Pedestal is a set of libraries that we use to build services and applications. It runs in the back end and can serve up whole HTML pages or handle API requests. There are a lot of tools in that space, so why did we build Pedestal? We had two main reasons. Pedestal is designed for APIs first. Most web app frameworks still focus on the "page model" and server-side rendering. Pedestal lets you start simple and add that if you need it. -

Amazon DynamoDB Session Store
Handles sessions for Ruby web applications using DynamoDB as a backend
The Amazon DynamoDB Session Store handles sessions for Ruby web applications using a DynamoDB backend. The session store is compatible with all Rack-based frameworks. For Rails applications, use the aws-sdk-rails gem. The session store is a Rack Middleware, meaning that it will implement the Rack interface for dealing with HTTP request/responses. This session store uses a DynamoDB backend in order to provide scaling and centralized data benefits for session storage with more ease than other containers, like local servers or cookies. ... -

Puma
A Ruby/Rack web server built for concurrency
Unlike other Ruby Webservers, Puma was built for speed and parallelism. Puma is a small library that provides a very fast and concurrent HTTP 1.1 server for Ruby web applications. It is designed for running Rack apps only. What makes Puma so fast is the careful use of a Ragel extension to provide fast, accurate HTTP 1.1 protocol parsing. This makes the server scream without too many portability issues. If you are using Bundler, just add Puma to your project's Gemfile. Once you've installed your bundle, start Puma. ... -

Pundit
Minimal authorization through OO design and pure Ruby classes
Pundit (varvet/pundit) is a Ruby gem that provides a simple and effective framework for adding authorization logic to Rails (or other Ruby) applications. It centers around policy classes—one policy per model or resource—that define what actions a given user is permitted to perform (e.g., show?, update?, destroy?). Each policy method returns a boolean, and can be structured using combinators or shared logic to keep things DRY. In controllers and views, Pundit provides helpers like authorize,... -
