Don't pay up to 10% of your monthly AWS bill to report on AWS charges and Instance usage with products like Cloudability and Cloudcheckr. Get a Splunk! free license and the free app Splunk App for AWS usage tracking (http://apps.splunk.com/app/1274/). This presentation from splunk > live! San Francisco 2013 shows how Edmodo stays on top of Reserved Instance usage and uses AWS resource tag-based reporting to help teams manage their AWS usage,

4. 100’s of
production, development, reporting
and operations instances are
managed on Amazon Web
Services Elastic Compute Cloud.
20 employees across 5 teams can
launch EC2 instances.

5. We tried lots of slow, pricey, hosted apps.
None had what we REALLY Needed …

6. Real Time RI vs On-Demand Usage
Do we have enough RI coverage? Are our RIs being used?

7. Getting Usage Data In front of Teams
Making Real Time Usage Data Visible Encourages Action
Problem:
The default Splunk for AWS App configuration is
based on billing “subaccounts”, which Edmodo
does not use.
Edmodo uses tags to differentiate between cost
centers.

8. Use These Tags: Product, Service, Space
Configurable Metadata Available for All AWS Resources
• Product
▸ designation is derived from the
end user perspective. Where
component resources serve
overlapping Products, the
Product designation is that which
uses/requires a resource most or
the resource's reason for existing.
• Service is the primary function of
the resource. Examples are
▸ mysql
▸ apache
▸ active-directory
• Space a logical workplace
designation. Examples are:
▸ Development
▸ Production

9. Edit the Splunk For AWS Scripts for Tags
get_instances.py and get_ops.py

10. Create Lookup Tables For The Tags
Simple .csv files are referenced by dashboard view files

11. Personalize Your Dashboard Views
The Dashboard XML format is easy to customize

12. Drill Down Into Usage Data by Tags
Teams Can Now Evaluate Usage For The Services They Manage

13. Drill Down Into Usage Data by Tags
Teams Can Now Evaluate Usage For The Services They Manage
