When different configuration values are required in the official and test environments respectively, you can create namespaces to isolate the configurations in different environments.  When the data of multiple product lines needs to be isolated, you can also allocate a namespace to each product line.


  1. Log on to the ACM console, and select a region as needed in the upper-left corner.
  2. In the left-side navigation pane of the console, click Namespaces.
    The Namespaces page is displayed.
  3. In the upper-right corner of the page, click Create Namespace.
    The Create Namespace dialog box opens.

  4. Enter a namespace name in the dialog box, and click OK.
    Note Currently, one user can create up to five namespaces.
    For example, enter Development.
    The new namespace appears in the table on the Namespaces page, and the namespace selection area at the top of the Configurations page. The data of this namespace and that of other namespaces is completely isolated.
