AWS Storage Gateway

Amazon

S3

Block File

On-premises Data Center

Archive Backup Disaster

Recovery

Amazon

EBS

Amazon S3 Infrequent Access

• For data accessed less than two times a

month

Amazon Glacier

• Same durability as S3

• 3 to 5 hours restore time

• Up to 65% savings

• Great for archiving, long-term backups

and old data

Choose the right EC2 pricing plan for your business…

On-Demand

Instances

Reserved

Instances

Spot

Instances

Pay as you go for computing

power

Flat hourly rate, no up-front

commitments

Pay an up-front fee for a

capacity reservation and a

lower hourly rate (up to 72%

savings)

1-year or 3-year terms

RI Marketplace: Buy RIs with

short remaining terms

Pay what you want for spare

EC2 capacity: your instances

run if your bid exceeds the

Spot price

Potential for large scale at

low cost: When they’re

available, take advantage of

1,000s of Spot Instances at

up to 90% savings

With Spot the rules are simple

Markets where the price of compute changes based on

supply and demand.

You’ll never pay more than your bid. When the market exceeds your bid you get 2 minutes to

wrap up your work.

EC2 SPOT Blocks

Run continuously for up to 6 hours

Save up to 50% off on-demand pricing

Using a single additional parameter:

Spot Bid Advisor – aws-spot-labs

Easily use EC2 Spot

instances for

production workloads

Amazon EC2 Spot Bid Advisor

1) We make this easy using the

Spot bid advisor

2) With deliberate pool

selection and bidding, you

will keep your Spot instance

as long as you need to.

3) And with new features like

Spot fleet diversified we do

the heavy lifting for you...

Use Reserved Instances…

You commit to pay for an instance for one or three years

We reserve the capacity, and offer you considerable savings over On Demand

during the term

You decide how you pay:

No Upfront (Just hourly charges for all hours of the term)

Partial Upfont (Upfront Payment, plus hourly charges for all hours of the term)

All Upfront (Upfront Payment only)

Base Price - On Demand: No Commitment, Pay only what you use, no capacity reservation but once started no interruption

10% less - Scheduled Reserved Instances: Commit to Schedule of at least 1200 hours for one year, capacity reservation

30-60% less - Standard Reserved Instances: Commit to one orthree years, capacity reservation

40-60% less - Spot Blocks: Bid for 2-6 hours blocks ofuninterrupted time

Up to 85% less - Spot: Bid for instances, interrupted if market pricehigher than your bid price, 2mins advanced notice

Advanced Tactics

Augmented Auto Scaling

Offloading

Licensing

SaaS Considerations

Auto Scaling – It’s not just for Instances!

Adjust DynamoDB IOPs on the fly:

Dynamic DynamoDB

https://github.com/sebdah/dynamic-dynamodb

DynamoDB Lambda Autoscale

https://github.com/channl/dynamodb-lambda-autoscale

Offload Your Architecture

The more you can offload, the less

infrastructure you need to maintain, scale,

and pay for

Three easy ways to offload:

Introduce caching

Use Amazon CloudFront

Leverage existing Amazon web services

Caching Saves Money

DynamoDB Reads

Saved 3k reads per second

(>20k reads per second in total)Saved 20k reads per second!

Offload Popular Traffic to

Amazon S3 and/or CloudFront

License flexibility via Dedicated Hosts

When running Microsoft Workloads, for example:

Instance-host affinity allows you to comply with the 90-day rule

Per-core and per-socket visibility enables reporting at the

physical level

Placement controls ensure that instances run on the server you

want them to, helping you meet stringent compliance and

regulatory requirements

AWS Config allows you to record when instances start, stop, or

are terminated for license reporting and true-ups

SaaS Specific Tactics

SaaS provides new vectors for optimization:

Allocate cache to your most demanding users

Grant different instances to different customers

AWS Lambda cost model matches the pricing model of SaaS
