Server

Einhorn makes it easy to run multiple instances of an application server, all listening on the same port. You can also seamlessly restart your workers without dropping any requests. Einhorn requires minimal application-level support, making it easy to use with an existing project.

Modern SDK for Couchbase Server

Capistrano is an open source tool for running scripts on multiple servers. It’s primary use is for easily deploying applications. While it was built specifically for deploying Rails apps, it’s pretty simple to customize it to deploy other types of applications. This package is a deployment "recipe" to work with symfony (both 1 and 2) applications.

The rubber plugin enables relatively complex multi-instance deployments of RubyOnRails applications to Amazon's Elastic Compute Cloud (EC2). Like capistrano, rubber is role based, so you can define a set of configuration files for a role and then assign that role to as many concrete instances as needed. One can also assign multiple roles to a single instance. This lets one start out with a single ec2 instance (belonging to all roles), and add new instances into the mix as needed to scale specific facets of your deployment, e.g. adding in instances that serve only as an 'app' role to handle increased app server load.

Barista provides simple, integrated support for CoffeeScript in Rack and Rails applications. Much like Compass does for Sass, It also provides Frameworks (bundleable code which can be shared via Gems). Lastly, it also provides a Rack Application (which can be used to server compiled code), a around_filter-style precompiler (as Rack middleware) and simple helpers for rails and Haml. For more details, please see the the README file bundled with it.

A Rack compatible pure Ruby HTTP Server.

Client library for interacting with the CloudFoundry User Account and Authorization (UAA) server. The UAA is an OAuth2 Authorization Server so it can be used by webapps and command line apps to obtain access tokens to act on behalf of users. The tokens can then be used to access protected resources in a Resource Server. This library is for use by UAA client applications or resource servers.

A web server that can be spawned in any directory

When ShamRack doesn't quite cut it; when your JavaScript and non-Ruby code needs to hit an external API for your tests; when you're excited about spinning up a full server instead of faking out Net::HTTP: we present the Discoball.

em-eventsource is an eventmachine library to consume Server-Sent Events streaming API. You can find the specification here: http://dev.w3.org/html5/eventsource/

SequenceServer lets you rapidly set up a BLAST+ server with an intuitive user interface for use locally or over the web.

EventMachine implements a fast, single-threaded engine for arbitrary network communications. It's extremely easy to use in Ruby. EventMachine wraps all interactions with IP sockets, allowing programs to concentrate on the implementation of network protocols. It can be used to create both network servers and clients. To create a server or client, a Ruby program only needs to specify the IP address and port, and provide a Module that implements the communications protocol. Implementations of several standard network protocols are provided with the package, primarily to serve as examples. The real goal of EventMachine is to enable programs to easily interface with other programs using TCP/IP, especially if custom protocols are required.

MidiSmtpServer is the highly customizable ruby SMTP-Server and SMTP-Service library with builtin support for AUTH and SSL/STARTTLS, 8BITMIME and SMTPUTF8, IPv4 and IPv6 and additional features.

A systems integration framework, built to bring the benefits of configuration management to your entire infrastructure.

With more than one application server, validates_uniqueness_of becomes a lie. Two app servers -> two requests -> two near-simultaneous uniqueness checks -> two processes that commit to the database independently, violating this faux constraint. You'll need a database-level constraint for cases like these. consistency_fail will find your missing unique indexes, so you can add them and stop ignoring the C in ACID.

A Resque plugin. Adds locking, with optional timeout/deadlock handling to resque jobs. Using a `lock_timeout` allows you to re-acquire the lock should your worker fail, crash, or is otherwise unable to relase the lock. i.e. Your server unexpectedly looses power. Very handy for jobs that are recurring or may be retried.
