12. Finding and Eliminating Waste
• Underutilized or unused resources (EC2, EBS, RDS, etc.)
• EBS Snapshots retenation
• Archiving Amazon S3 Data to Amazon Glacier
• Reserved Instance purchase (EC2, RDS, Redshift)

14. Leveraging the Cloud to Reduce Costs
• Dev/test environments can be shut down at project termination.
• Shutdown specific services after business hours, during holidays.
• Disaster Recovery environments can remain inactive until you need
them.
• Tag resources that can be turned off or deleted after a specified
time period.

15. Parameters for Tagging
10 custom tags per resource.
Max key length: 127 Unicode characters.
Max value length: 255 Unicode characters.
➢ Non-ASCII characters return as Unicode escapes (example:
u65e5u672c).
Prefix aws: is reserved.
Few resources cannot be tagged; different
resources require using different commands.

16. Tag’s Key Examples
Business Unit Cost Center Owner
Shutdown Time Environment Support Contact
Dept./GroupApplication/ProductEndpoint

17. Tagging CLI Commands
Resource view: use --filter argument to the relevant
AWS CLI command:
➢ Provides access to all values regarding resource.
aws ec2 describe-instances --filter
"Name=tag:Role,Values=DEV"
Use --query to get list of specific values, such
as instance ID:
aws ec2 describe-instances --filter
"Name=tag:Role,Values=DEV"
--query 'Reservations[*].Instances[*].InstanceId'

20. Design for Cost Reduction
• “Right-size” & “Right-family” instances.
• Purchasing Reserved Instances (RI) for groups of long-running
instances.
• Leverage spot instances to get the best price.
• Use AWS obstructed services to leverage a “Pay as you go” model
to reduce cost(Lambda, DynamoDB, SQS, etc.).
• Design for server-less architecture.

22. Implementing governance policies and rules
• Track and manage changes like: launching new resources, tracking and
terminating unused or underutilized assets, sudden cost spikes, security risks
and adherence to business guidelines.
• Automate workflow for policy actions like: stop or terminate instances, delete
volumes, etc.
• Automate the process of purchasing and modifying reserved instances across
one of more accounts.
• Avoid costly surprises in your cloud. Proactively manage your cloud with
policy notifications and “Pulse” subscriptions for timely cost, usage,
performance, and budget considerations.

26. Netflix Ice
Ice communicates with AWS Programmatic
Billing Access and maintains knowledge of the
following key AWS entity categories:
• Accounts
• Regions
• Services (e.g. EC2, S3, EBS)
• Usage types (e.g. EC2 - m3.xlarge)
• Cost and Usage Categories (On-Demand,
Reserved, etc.)

27. EverythingMe ncdu-s3
NCDU stands for NCurse Disk Usage which is
Linux program that displays Disk usage
statistics in a Ncurse menu, which makes
things easier where you don’t know exactly
where to start – Giving you a good overview
and letting you know where is the bottom of
disk space issues.
No imagine these abilities over S3 buckets!

28. • Power Scale - Take control of your AWS Auto
Scaling.
• Power Cycle - No more wasted AWS EC2
usage.
• Alerts - Put an end to AWS billing surprises
• Teams - Sophisticated permissions for
multiple users
• Integration with Slack and HipChat

29. https://github.com/GorillaStack/auto-tag
This is an open-source tagging solution for
AWS. Deploy auto tag to lambda and set up
CloudTrail and have each of your resources
tagged with the resource who created it. It was
written by GorillaStack.

With the CloudHealth’s platform, customers can
control their data through knowledge.
CloudHealth can quantify, understand, optimize
and automate its cloud resources, giving
customers visibility across their entire cloud
ecosystem to effectively optimize resources
and define governance policies for ongoing
management. CloudHealth allows customers to
scale their cloud without scaling their IT
workforce.
