Atlassian has established new development and testing criteria for Marketplace apps used in Data Center environments. These include elements of how apps handle cache operations, support required databases, implement locking and availability in clustered environments, manage event handlers and much more.
These new standards mean when you purchase a Data Center approved app, you can be confident it will meet the high demands of your large-scale Data Center environment. In order to be listed as a Data Center approved app, developers must present evidence that they have met these new standards and their testing results must be approved by Atlassian.
To learn more about the importance of using Data Center approved apps, see the Atlassian Data Center FAQ.
