| − | [[CNM Cloud requirements]] is a set of detailed requirements for [[CNM Cloud]]. This document has been drafted to assist cloud developers to come up with detailed implementation of [[enterprise private cloud]] with an objective to host [[BigBlueButton]], [[Moodle]], [[MediaWiki]], [[Odoo]], and [[Redmine]] [[end-user software application]]s. Each of these application shall serve more than 100 users with a peak load capacity of 20 simultaneous users. The requirements have been drafted keeping in mind that users of above applications would require an uninterrupted very high availability. | + | [[CNM Cloud requirements]] (previously known as [[CNM software requirement]]s and [[CNM app requirement]]s) is the [[requirements specification]] for [[Opplet]] (hereinafter, the ''Cloud''). |
| | | | |
| − | The target audience for this document is [[cloud architect]]s, [[DevOps engineer]]s and [[system administrator]]s.
