Projects / Prudence


Prudence is a platform for creating scalable Web applications and network services using dynamic scripting languages and proven REST principles. Your application can support thin clients (HTML) and rich clients (AJAX), with anything in between. You can also create pure REST services with no user interaction. Languages supported are Python, Ruby, Groovy, Clojure, JavaScript, PHP, Succinct, Velocity, and anything else supported by the Scripturian project.

New features include integrated caching of your Web APIs, modular installation, advanced templating, MVC, and support for the Lua programming language. It's also ready for JVM 8 right now, making full and good use of the Nashorn JavaScript engine.

        Release Notes: Instances of Prudence now automatically discover each other and form clusters (via Hazelcast) that can share global data and tasks. This lets you easily farm out your work in the cluster for super-scalability and redundancy. It has been tested with 100 nodes on EC2. This release is identical to RC13.
