AWS Tags and Uses in AWS Services

AWS Tags and Uses in AWS Services

INTRODUCTION:

Amazon web service allows the customer to assign metadata to their AWS resources in the form of tags. Each tag is a simple label consisting of a customer-defined key and an optional value that can make it easier to manage filter resources by purpose, owner, environment. AWS Tags and Uses is various AWS services.

Tag Basics:

A tag is a label that you assign to an AWS resource. Each tag consists of a key and an option value, both of which you define. Tags enable you to categorize your AWS resources in different ways, for example, by purpose, owner, or environment.

How tagging works:

We have assigned two tags to each of our instances -one tag with the key “Owner” and another with the key “Stack”. Each tag also has an associated value. We recommended that your device a set of tag keys that meets your needs for each resource type. Tags don’t have any semantics meaning to amazon EC2 and are interpreted strictly as a string of characters. Also, tags are not automatically assigned to your resources. you can edit tag keys and values, and you can remove tags from a resource at any time. You can set the value of a tag to an empty string, but you can’t set the value of a tag to null. if you add the tag that has the same key as an existing tag on that resources, the new value overwrites the old value.

Working with tags using the console:

We can see which tags are in use across all of your Amazon EC2 resources in the same region. You can view tags by resources and by resources type, and you can also view how many items of each resource type are associated with a specified tag

  • Displaying tags
  • Adding and deleting tags on individual and group resources
  • Adding a tag when you launch an instance
  • Filtering a list of resources by tag

AWS Spending that can’t Be tagged

There’s a whole bunch of spending in your monthly AWS bill which isn’t classified as direct resource usage and therefore can’t be tagged.

Monthly recurring reserved instances fees. At the begging of each month, AWS applies 720 hours of pre-pay for each partial or no upfront reserved instances.

Sign up free for reserved instances. For all upfront and partial upfront reservations. you’ll pay a one-off signup fee.

AWS support fees. For regular business support or enterprise support.

Tax: in Australia, for example, you’ll see GST as an item that can’t be tagged.

Actual resources that can’t be tagged

Here is a partial list of items that cannot be tagged:

  • CloudWatch MetricMonitorUsage
  • EBS snapshots- although these can be tagged, when AWS reports on them spending is collapsed to account /region with no resource id or tags mage available.

Things that CAN be tagged

  • EC2, RDS, and redshifts instances
  • S3 buckets, including storage, and request costs
  • Data transfer will inherit the tags of its resources source
  • Additional EBS volumes
  • RDS storage
