Tag Your Spot Fleet EC2 Instances
Amazon EC2 Spot Fleet now supports user tags that will automatically propagate to instances launched by your Fleets. This makes it easier for Spot Fleet customers to track ownership, drive their cost accounting processes, implement compliance protocols, and to control access to Spot instances via IAM policies.
Previously, if you wanted to tag instances launched by Spot Fleet you had to write and manage custom code. Now you can provide up to 50 user tags per launch specification and let Spot Fleet automatically tag instances it launches on your behalf.
Tags enable you to categorize your AWS resources in different ways, for example, by purpose, owner, or environment. This is useful when you have many resources of the same type — you can quickly identify a specific resource based on the tags you've assigned to it. Each tag consists of a key and an optional value, both of which you define. For example, you could define a set of tags for your account's Amazon EC2 instances that helps you track each instance's owner and stack level.
Tagging is available today in all regions where Amazon EC2 Spot Fleet is available. For more information, click here.
