<h1 class="topictitle1">Adding Tags to AS Groups and Instances</h1>

<div id="body1500376665684"><div class="section" id="as_06_0104__section2495449014355"><h4 class="sectiontitle">Scenarios</h4><p id="as_06_0104__p1622395820217">If you have many resources of the same type, you can use a tag to manage resources flexibly. You can identify specified resources quickly using the tags allocated to them.</p>
|
|
<p id="as_06_0104__p152183534">Using a tag, you can assign custom data to each AS group. You can organize and manage AS groups, for example, classify AS group resources by usage, owner, or environment.</p>
|
|
<p id="as_06_0104__p16708589317">Each tag contains a key and a value. You can specify the key and value for each tag. A key can be a category associated with certain values, such as usage, owner, and environment.</p>
|
|
<p id="as_06_0104__p57613131331">For example, if you want to distinguish between the test environment and production environment, you can allocate a tag with the key <strong id="as_06_0104__b84235270616226">environment</strong> to each AS group. For the test environment, the key value is <strong id="as_06_0104__b842352706162244">test</strong> and for the production environment, the key value is <strong id="as_06_0104__b84235270616239">production</strong>. You are advised to use one or more groups of consistent tags to manage your AS group resources.</p>
|
|
<p id="as_06_0104__p12289145174811">After you allocate a tag to an AS group, the system will automatically add the tag to the instances automatically created in the AS group. If you add a tag to an AS group or modify the tag, the new tag will be added to the ECSs automatically created in the AS group. Creating, deleting, or modifying the tag of an AS group will have no impact on the ECSs in the AS group.</p>
