While Atlassian offers a cloud-based solution to their products, there are a number of reasons why an individual or a company might not want to purchase a subscription.
It might be because a local instance is required, because of the available plugins. The JIRA server version has a vast amount of plugins that are not compatible with Atlassian Cloud.
There also might be a requirement to protect sensitive data and disallow online connectivity.
Whatever the reason, Atlassian offers both a Cloud hosted or a local server instance of JIRA.
