9. Renting in Cloud mall
In the Cloud mall you
can rent by square

If:
you need more, you
get more

38. Failures
Cloud is not immune to
failures
Cloud Apps should be
designed with failure in
mind (distributed
components app)
Take advantages of:
Availability Zones
Multiple Regions

39. One more thing: API!
All services are manageable through a Web Console
But all AWS services have exposed APIs
You can (for example):
Allocate, start, control, terminate EC2 instances
Allocate/attach/deallocate EBS partitions
Allocate/start/stop databases
Create/Read/Update/Destroy S3 objects
Change IPs
Monitor components
...

40. Predicting costs
Amazon Simple
Monthly Calculator
(google it!)
Given some
assumptions, how
much will I pay?
BetterSoftware ‘11

41. Keep costs low
Use a mix of reserved
instances vs. On-
Demand instances
Undersize your storage
and processing power
Monitor process
activities (e.g. you pay
for the bandwidth)
Use AutoScale

42. Conclusions
Cloud is a very good place
to host your application
and data
Very flexible, leaves to
others the pain of
operations
Easy to migrate to Cloud
in steps (subscribing one
service at a time)
Your application is ready
to scale with your business
