Weighing the financial considerations of owning and operating a data center facility versus employing a cloud infrastructure requires detailed and careful analysis. In practice, it is not as simple as just measuring potential hardware expense alongside utility pricing for compute and storage resources. The Total Cost of Ownership (TCO) is often the financial metric used to estimate and compare direct and indirect costs of a product or a service. Given the large differences between the two models, it is challenging to perform accurate apples-to-apples cost comparisons between on-premises data centers and cloud infrastructure that is offered as a service. In this session, we explain the economic benefits of deploying applications in AWS over deploying equivalent applications hosted in an on-premises environment.

Analysts have shown AWS reduces costs

In early 2012, AWS commissioned IDC to interview 11 organizations that deployed applications on AWS. Since this study was conducted in early 2012, AWS has introduced price reductions nearly 20 times across Amazon EC2 and Amazon S3. IDC estimated what the impact of AWS's fee restructuring would be on the organizations that participated in the 2012 study and determined that the overall fees would drop by 21% lowering the five year TCO from $909,000 to $846,000.

According to IDC, this relationship between length of time using AWS and return is due to customers leveraging the more optimized environment to generate more applications along a learning curve.

Cost Optimization on AWS

1. Choose the right instance types

Start Choose an instance that best meets your basic requirements

Start with memory & then choose closest virtual

cores

Look for peak IOPS storage requirements

Tune Change instance size up

or down based upon monitoring

Use CloudWatch & Trusted Advisor to assess

Roll-Out Run multiple instances in multiple Availability

Zones

2. Use Auto Scaling Describes what Auto Scaling will create when adding Instances

Only one active launch configuration

at a time

Launch Configuration

as-create-launch-config --image-id ami-54cf5c3d --instance-type m1.small --key mykey --group webservers --launch-config 101-launch-config

Auto Scaling managed grouping of EC2 instances

Automatically scale the number of

instances by policy – Min, Max, Desired

Auto Scaling Group

as-create-auto-scaling-group 101-as-group --availability-zones us-east-1a us-east-1b --launch-configuration 101-launch-config --load-balancers myELB --max-size 5 --min-size 1

Parameters for performing an Auto Scaling action

Scale Up/Down and by how much

Auto Scaling Policy

as-put-scaling-policy 101ScaleUpPolicy --auto-scaling-group 101-as-group --adjustment=1 --type ChangeInCapacity --cooldown 300

Utilization and Auto Scaling: Granularity more small instances vs. less large instances

29 m1.large @ $0.240/hr. = $6.96

59 m1.small @ $0.06/hr. = $3.54

3. Turn off un-used instances

•  Dev./test instances •  Simple instance start/stop •  Tear down/build up altogether •  Instances are disposable

4. Use Reserved Instances Reserved Instances enable you to maximize savings by paying a low, one-time fee for a capacity reservation of 1-3 years in exchange for a significant discount on the hourly rate.

AWS Set-up

•  8 billion objects and 400 terabytes of data (May 2012), 10x growth from August 2011; EC2 instances have grown by 3x in the same time period

•  150 EC2 instances ( web tier), 90 instances (in-memory caching), 70 master databases •  Reserved instances used for standard traffic; On-demand and spot instances used to handle daily elastic

load. Most services targeted to run at about 50% on-demand and 50% spot

“Imagine we were running our data center, and we had to go through a process of capacity planning and ordering and racking hardware. It wouldn't have been possible to scale fast enough,"– Ryan Park, Pinterest Operations Engineer

Costs have gone from $54 per hour to $20 per hour

Only 2 weeks of engineering effort was required to achieve this cost savings

5. Use Spot Instances

•  Pricing •  Up to 92% discount

•  Elastic •  Capacity not otherwise

available

•  Tradeoff •  Potential for interruption

Amazon S3 Reduced Redundancy •  99.99% durability vs.

99.999999999% •  Up to 20% savings •  Great for everything that is easy to

reproduce

Amazon Glacier •  Same durability as S3 •  3 to 5 hours restore time •  Up to 67% savings •  Great for archiving, long-term
