Tag Your Auto Scaled EC2 Instances
EC2’s Auto Scaling feature gives you the ability to define and then launch an Auto Scaling Group of Amazon EC2 instances that expands and contracts as necessary in order to handle a workload that varies over time. You can define scale-up and scale-down events that are triggered by the Amazon CloudWatch metrics that are most indicative of your application’s performance.
Because the instances are launched automatically, identifying them can sometimes be difficult. We’re solving that problem today by giving you the ability to define up to ten tags that will be associated with each EC2 instance launched by a particular Auto Scaling Group.
Here’s how you define the tags in the AWS Management Console:
You can, of course, see the tags in the EC2 section of the console:
You can also edit the tags of an existing Auto Scaling Group; they will be applied to all newly launched EC2 instances.
This new feature is available now and you can start using it today!
