In order to be listed as a Data Center approved app, developers must adhere to new, more-rigorous development and testing criteria, designed to ensure such apps will perform to the unique requirements of large-scale Data Center environments. These addition tests focus on the unique needs of Data Center instances, such as caching, database support, clustered environments, and more.
In order to be considered for Data Center approval, developers must:
Complete a 100+ question readiness assessment, including an architectural review
Complete additional testing to evaluate their apps in an environment that simulates a large-scale Data Center instance
Once these additional steps are completed, Atlassian evaluates the readiness of each app and makes the final decision of whether an app can be designated Data Center approved.
