Definition

Cloud computing is on-demand access to virtualized IT resources that are housed outside of your

own data center, shared by others, simple to use, paid for via

subscription, and accessed over the Web

SaaS vs. IaaS vs. PaaS(+ Capgemini partners)

Software as a Service (SaaS): Complete application systems delivered over the Internet on some form of "on-demand" billing system: Salesforce.com, Google Apps…

Platform as a Service (PaaS): Development platforms and middleware systems hosted by the vendor, allowing developers to simply code and deploy without directly interacting with underlying infrastructure: Google AppEngine, Microsoft Azure, Force.com…

Infrastructure as a Service (IaaS): Raw infrastructure, such as servers and storage, is provided from the vendor premises directly as an on-demand service: Amazon Web Services,…

Case Study: Eli Lily

“…pressure was growing to reduce fixed IT costs without compromising on IT services…”

“…with AWS a new server can be up and running in three minutes (it used to take Eli Lilly

seven and a half weeks to deploy a server internally)…”

http://www.informationweek.com/cloud-computing/blog/archives/2009/01/whats_next_in_t.html

“Eli Lilly uses AWS to provide high-performance computing, as needed, to hundreds of its

scientists.”




Case Study: NYT Time Machine

Offer 150 years of newspaper to the public online

Challenge: 4 TB of data • 405.000 very large TIFF images• 3.3 million SGML articles• 405.000 XML mapping files

Convert to:• 810.000 PNG images• 405.000 JavaScript files


Case Study: NYT Time Machine

Imagine a couple of seconds per conversion easily 1 month of work!

NYT did it in 36 hours using hundreds of AWS instances (using EC2, S3 and Hadoop)


Speed of provisioning is constraining business execution

Enterprise Datacenter no longer provides competitive advantage

Existing hardware has reached end of serviceable life

Internal datacenter capacity limits are being reached

Applications & processes have highly variable demand

When Is Cloud Computing A Fit For The Enterprise?

COST OF CLOUD


Cloud computing = cheaper?

Calculations by Chris Fleck of Citrix

On-premises: $7800/year Colocation: $13,800/year Amazon EC2: $35,040/year

Is cloud interesting when you are always using 100%?

Cloud CAN be a cost saverwhen used appropriately.


What can we do with cloudNOW that we couldn’t do

BEFORE?
