3. What's that cloud ?

4. Cloud is trending
And the ash cloud has (almost) nothing to do with this

5. Cloud is short for “cloud computing”

6. It has a growing impact on enterprise IT

7. And is definitively becoming mainstream

8. I mean... really really mainstream

9. One amongst... hundreds of definitions

10. 3 kinds of clouds

11. Software as a Service
Platform as a Service
Infrastructure as a Service

12. SaaS
SaaS: On-premise software replaced by PaaS
IaaS
subscription based web applications
Key advantages

Pay per use (montly or annual fee)

Usage based pricing (not “seats”)

Competitive pricing (scale effect)

No software setup/upgrade

No infrastructure to manage

13. SaaS
Example: Google Apps has 4 times lower PaaS
IaaS
TCO than on-premise MS Exchange

14. Software as a Service
Platform as a Service
Infrastructure as a Service

15. SaaS
PaaS: A platform to deploy web applications PaaS
IaaS
Key advantages

Usage based pricing (request, space, ...)

Auto-scaling

Limited operations required

Increased availability

Added services like CDN, monitoring, ..

16. SaaS
Example: Building your own stack and PaaS
IaaS
running your application with DotCloud

17. Software as a Service
Platform as a Service
Infrastructure as a Service

18. SaaS
IaaS: A web service to 'launch' new servers PaaS
IaaS
and pay per use
E.g. Launch a new server with a simple command line call or an API call
> ec2-run-instances ami-446abc01 -k my-keypair
Key advantages

Usage based pricing (cpu, space, ...)

Per-hour billing (elasticity)

No infrastructure (network, cooling,..)
to worry about

Added services like CDN, monitoring, ..

19. SaaS
Animoto: The first success story of IaaS PaaS

your own pictures

20. SaaS
Animoto: Scaling from 50 to 3500 servers in PaaS
IaaS
3 days
Facebook app was an instant
success. Adding 20,000 users
every hour.
They needed to scale from 50 to
3500 servers in 3 days.
How do you do that with
conventional IT ?
Can you imagine the upfront
capital expenditure ?

21. One more thing...
Public Cloud
Private Cloud

22. The rise of the 'private' cloud
I.E. Using the same ideas but inside your own datacenters

23. The rise of the 'private' cloud
I.E. Using the same idea but inside your own datacenters
“Worldwide server revenue associated with private
clouds is forecast to grow more quickly than that
associated with public clouds.”
