Ruby gems are a way of adding functionality to programs written in Ruby, including the popular web application framework Ruby on Rails. Gems are also a way for people to share their code to the world and contribute to open source.

After you set up your server, its time to deploy applications into it. One of the most popular web application frameworks is Ruby on Rails. This is built using the Ruby programming language and it enables developers to create web applications ranging from quick prototypes and Minimum Viable Products (MVPs) up to large distributed applications. Rails is an opinionated framework, meaning there is a standard way of doing things, but it can also be modified to suit your preferred architecture and coding style. By default however, Rails provides sensible and secure defaults that will help you run and deploy your applications quickly. Through using Ruby gems to augment functionality, you can create a fully-functional web application in a short amount of time.
