ライセンス: ユーザー管理を Jira に委譲します。Jira と Confluence でいくつのライセンスが必要ですか
Can I delegate user management to JIRA and Confluence?
Server / Cloud
Atlassian Cloud has common user management for both JIRA and Confluence. Therefore, we are not delegating user management to JIRA. This means you'll need to license as many users that you need in each product.
For Server, if you are managing users with JIRA for your Confluence, you'll only need to license as many users in each product using it. If you add a user in JIRA to manage their access to Confluence but that user will not be using JIRA itself, you do not need to buy a license for this user in JIRA.
In both, Cloud and Server, subscriptions and licenses (respectively) are sold in user tiers.
