The document discusses how cloud users can improve cost-efficiency. It introduces Teevity and Objectif Libre, companies that provide cost analytics and OpenStack expertise. Cloud architectures are compared to LEGO bricks, with different options having varying capabilities and costs. True cost-efficiency requires balancing value and cost. The document promotes autoscaling, reducing idle resources, and using CloudKitty and OpenStack to provide cost visibility for public and private clouds.

11. Building on a Cloud
How do we build software architectures on a Cloud ?

12. Like Playing LEGO !

13. Different bricks have...
 Different capabilities
 Different QoS
 Different cost-efficiency levels
 Different elastic-capabilities
- different abilities to reduce the consumption when resources
not needed anymore (instant elasticity vs slow elasticity)
 The Bricks you choose have an impact on the
cost efficiency !

14. Defining cost-efficiency

15. Definition
CostEff =
valueProduced / costIncurred

16. Le projet pas à pas… les solutions apportées
 Define Value ?
- != Performance
- Many approaches
 Gain ($) generated by unit of time
 Technical approach (near to performances)
✔
Number of transaction / seconds
 What about the confort of usage
✔
AWS investments for performance with confort
finality
 Cost is way more simple...
Let's detail the elements

17. Cost-Efficiency comes with a Cost
 The ideal is a system that goes live ONCE the
user needs it
- Easily compatible with Cloud and Software
Defined Infrastructure
- What about latency ?
 Even if Docker might help…
 A system that always maximized the available
resources is bare metal…
- What about evolution ?

19. Cost-efficiency for all !

20. Empower Public Cloud users
 The natural quest…
 Public Cloud to avoid paying big numbers !
- Teevity is there for you !!!

21. Empower Private Cloud users
 The natural quest
…to whoever runs the cloud
 avoid internal saturation !
 Quotas are NOT the solution !
 Chargeback
- For real transactions
- Likewise Public Cloud
 Showback
- As education purposes

22. What about Free Software / Open Source ?
 Cost definition / Reporting
… and the OpenStack blankness …
… CloudKitty for helping …

23. Let us introduce you… CloudKitty
The Rating Component for OpenStack
 Developed with full respect of OpenStack best practices
 Interfacing with Ceilometer API and much more
 Integrated with OpenStack and Horizon
 Highly-modular
Metrics

(Ceilometer
or other) API
Rating policy configuration
Tarif view, even before
resource activation
Cost analysis follow-up
Usage live follow-up and
history
User view

27. Autoscalling (3)
 An effort needs to be done
- Speed of boot
- Session handling
- Autoscale smoothly
 Keep in mind sessions…
 As a side note : put the autoscalling mecanisme
OUTSIDE the application

28. Check/Reduce Resources Consumption
 Don't waste your money on CPU Cycle !
 Use whenever you can some heavily
threaded applications
 Even energy-friendly !
