Cost Optimization at Scale
David Costa
CTO
Fredhopper
What to expect….
We will introduce our approach for building
the business case for moving to the cloud
and share tips from some of our most
innovative customers who are able to
successfully architect for cost optimization
in order to realize the economics of the
AWS cloud.
In the beginning . . .
…there was TCO
What is TCO?
Definition: Comparative total cost of ownership analysis (acquisition
and operating costs) for running an infrastructure environment end-to-end
on-premises vs. on AWS.
Used for:
1) Comparing the costs of running an entire infrastructure environment or
specific workload on-premises or in a co-location facility vs. on AWS
2) Budgeting and building the business case for moving to AWS
So how do we do it?
≠
TCO = acquisition costs + operations costs
Hardware—server, rack
chassis PDUs, Tor switches
(+maintenance)
Software—OS,
virtualization licenses
(+maintenance)
Facilities cost
Hardware—storage disks,
SAN/FC switches
Storage admin costs
Network hardware—LAN
switches, load balancer
bandwidth costs
Network admin costs
Server admin virtualization admin4
The diagram doesn’t include every cost item. For example, software costs can include database,
management, and middle-tier software costs. Facilities cost can include costs associated with upgrades,
maintenance, building security, taxes, and so on. IT labor costs can include security admin and application
admin costs.

So you’re feeling pretty good.
Cost optimization is…
going from…
to…
pay for what you use
pay for what you need
Where do you start?
The four pillars of cost optimization
Right-sizing Reserved
Instances
Increase
elasticity
Measure,
monitor, and
improve
Right-sizing
Right-sizing
• Selecting the cheapest instance available
while meeting performance requirements
• Looking at CPU, RAM, storage, and network
utilization to identify potential instances that
can be downsized
• Leveraging Amazon CloudWatch metrics and
setting up custom RAM metrics
Rule of thumb: Right size, then reserve.
(But if you’re in a pinch, reserve first.)
Reserved Instances
Commitment level
1 year
3 year
AWS services offering RIs
Amazon EC2
Amazon RDS
Amazon DynamoDB
Amazon Redshift
Amazon ElastiCache
* Dependent on specific AWS service, size/type, and region
Reserved Instances
Step 1: RI Coverage
• Cover always-on resources.
Step 2: RI Utilization
• Leverage RI flexibility to increase utilization.
• Merge and split RIs as needed.
Rule of thumb: Target 70–80% always-on
coverage and 95% RI utilization rate.
Increase elasticity
Turn off nonproduction instances
• Look for dev/test, nonproduction instances that
are running always-on and turn them off.
Autoscale production
• Use Auto Scaling to scale up and down based
on demand and usage (for example, spikes).
Rule of thumb: Shoot for 20–30% of Amazon EC2
instances running on demand to be able to
handle elasticity needs.
Using right-sizing and elasticity to lower cost
More smaller instances vs. fewer larger instances
29 m4.large @ $0.12 /hr
$2,505.60 / mo*
59 t2.medium @ $0.052/hr
$2,208.96 / mo*
*Assumes Linux instances in US-East at 720 hours per month
Putting it all together: case study
Challenge:
Minimizing unit costs
under period of massive
growth.
A consistent measure of
CPU processing power
Elastic compute unit
(ECU)
The growth challenge
August 2014
August 2015
584 ECU
1,192 ECU
2x
YoY Compute Growth
33%
decrease in monthly
EC2 costs!
Solving the growth challenge
Step 1: Right-size and update instances
m1 on demand
$0.07 per ECU
c4 on demand
$0.02 per ECU
The impact of right-sizing
70% reduction
in unit cost
Step 2: Reserve
The impact of reservations
30% reduction
In unit cost
Putting it together
85% reduction
in unit cost!
Sounds pretty easy, right?
Not really.
In reality, it is very complex.

Conclusion
Takeaways from Fredhopper
Cost structures beside cost savings provides a
culture of utilization and cost awareness
It does work! We saved $1.7M last year in EC2
costs
The team is rewarded by those cost reductions: part
of the savings funds innovation and green fields.
Thank you!
Sounds pretty easy, right?
Not really.
