Python

Zenoss is primarily programmed in Python. Python(R) is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries. Many Python programmers report substantial productivity gains and feel the language encourages the development of higher quality, more maintainable code. Zenoss chose to use Python because it offers the structure for robust enterprise applications but is flexible enough to adhere to a quick-paced development schedule.

Zope

Zope is an open source web application server primarily written in the Python programming language that is the foundation for the Zenoss application. It features a strong through-the-web development model, allowing you to update your web site from anywhere in the world. To allow for this, Zope also features a tightly integrated security model. Built around the concept of "safe delegation of control", Zope's security architecture also allows you to turn control over parts of a web site to other organizations or individuals. The transactional model applies not only to Zope's object database, but to many relational database connectors as well, allowing for strong data integrity. This transaction model happens automatically, ensuring that all data is   successfully stored in connected data sources by the time a response is returned to a web browser or other client.

Zope is released under the Zope Public License (ZPL).
