6. Scale-Up architecture
N-TIER ARCHITECTURE System-centric
Complicated assemblies of
frameworks
| Architecture Week

7. Network of linked information User-centric
Unanticipated uses
REST INTERNET ARCHITECTURE Scale-out architecture
Simple protocols and formats
instead of frameworks

8. Architecture of the Web
Tim Berners Lee
The Inventor of the web
‘‘The value of the Web lies in the
unanticipated reuse that it allows’’
‘‘Designed to facilitate the future uses
that we do not know’’
The Web is based on a Ressource Oriented
Architecture called REST
URI & multiple representations

9. The Internet and the Web as Models
Html 5 js engine
Browser Search
In-memory data grid no-sql
Technologies,
Architectures and Practices
validated by Millions of Users
&
very demanding Business Models
IT performance has direct impact on revenues
Many page views & clicks needed for 1 K€ orders
Decision making process to maximize learning & differentiation

14. A Big Wave of Disruptive Technologies
Cloud Computing – Everything is elastic
You want 1 – 10 - 100 servers
for 1 hour - 10 hours -
10 weeks - 10 months
You Got It !
Commodity Technologies
Very large economies of scale
No investment before use.
Pay for what you need, when you need.
Instead of investing in rigidity, you buy flexibility.

15. Cloud Computing
‘‘ The risk for enterprises that don’t start
a Cloud migration is that their IT
organization will be a competitive
disadvantage. ’’
Geir Ramleth
CIO, Bechtel Corp
Not Only
Cost Reduction
But also
Business Agility
Access to next-generation architectures

16. Big Data delivers Big Value
More of everything
Data Deluge Big Data = Volume + Diversity + Velocity
Big Data is about Size, Complexity
and about
Big Data is the future of IT
Sharing to derive value
Collect

17. Wallmart handles more than 1 M customer transactions
per hour feeding databases estimated at more than
2.5 petabytes.
These data could be shared with Wallmart suppliers to
run Vendor Managed Inventory (VMI) practices

18. A Big Wave of Disruptive Technologies
Mobile devices and the end of the PC era
In 2011, the number of mobile devices will pass the
number of desktop PCs.
ATAWAD access to all information and services.
Any Time Any Where Any Device
Apple has changed the game [again]
In 1993 the iPad 2 would have been among the
top 30 supercomputers in the world.
World No. 3 computer maker…if iPad is a computer.
Jobs' approach to the future of computing:
Make everything simpler, more universally usable,
and less constrained by the narrow orthodoxies of the
tech industry.

25. A shift in mindset
Stop thinking:
We build a collection of applications
that support our business
Application Silos
Start thinking:
We build our business using
technology platforms
Time To Value
Tools & Services allowing
fast & continuous
delivery of user features A Copernican shift

26. Think about project differently
Technology Driven
Business Differentiation
Automate the tasks & Transformation
we know [as must be done]
Increase Business performance
in complex working situations
Usages are well known New Usages
One can completely specify 30% of the specifications
the system before building it are unknown the 1st day of the project
Agile project driven by
Fixed price engagements bunisess value analysis
Long Cycles Short Cycles
& iterations
New engagement models

27. Agile Development Process
The “agile” approach consists in
implementing functions by “business” Collaboration
priority, with “continuous” flexibility
and acceptance of business change
Deliver & test early
to build the right software

28. Business Value Driven Process
High Priority
Backlog sprint
During each iteration, the top priority
items get implemented
Items with a high
priority are detailed
New items are integrated
with their priority level
Items in the backlog can be
reprioritized at any time
Items with a low
priority are described
in a simple way Items can be removed
from the backlog at any time
Low Priority
Product Backlog
Requirements expressed from the user perspective

Assumptions :
The customers know what they want
The developers know how to build it
Nothing will change along the way

Assumptions:
The customers discover what they wants
The optimal architecture is emerging
Things change along the way

31. Agile & Architecture
Traditional Project Agile Project
Big Design Up Front Continuous Design Work
Gradual Emergence
Elaborate a detailed architecture at A global vision and a good foundation
the [very] beginning of the project are needed to deliver sprints
Peer Review The architecture must be designed to
Defining the right architecture support rapid changes and to support
at the 1st time is a critical factor automated testing
Start with a simple architecture and
improve it continuously at each iteration
The only way to test a design is to
implement it !
Design Review at the end of sprints
