Summary

4. You want to build a house…
You hire a software architect…
You discuss requirements…

5. Prototyping…
Sorry, not much to show you right now…

6. Prototyping…
You wanna see some UML diagrams?

7. Prototyping…
But trust me – it’s going to be great!

8. The Result…
12 months later…

9. Static Structure
„Point of no return“ due to late „visual“ results
No adjustments during the project
Result: You buy the black box
Human failure
DRY: Don‘t repeat yourself (e.g. Writing a DAL)
More code means more bugs 
Result: Errors occur „by design“

10. Model
Your Business Requirements
To describe capabilities
To enable your software to solve business problems
Your Application
To match capabilites
To enable „design for change“
Your Development
To have a structure
To enable adjustments often an early if nessecary
Your Operations
To identify application health
To enable immediate response on issues

11. ...think up in front!
Before you start modeling it is a must to think
through the domain and understand the
context!!!
If you only understand parts of it, think of it
again!!!
Adjust your mind setting from time to time ;-)

13. From Towards
Loosely-coupled resources provide
services which are designed to
interact with each other

15. You have to be very agile
Aggregating foreign content
Switching business partners
Your operational costs explode
Complex systems are complex to manage
A new host system is not an option
You start small and fast grow is obvious
Almost every sucessful web site
Your business model rocks!

21. devcoach® SOA3
Define Tasks
Devide a huge package of work into smaller units
aka Services
Build Interfaces
Describe capabilities and data of a task
aka Service Contract
Create Interaction
Describe how tasks act in combination
aka Workflow

22. BlueBooks – Yet another book store?

23. Feature Driven Development
Create a Project Vision and Personas
What is the project all about and who will use it
Define Modules
Devide a huge package into smaller units
E.g. a Service
Define Features
Describe capabilities of a module
E.g.: Business capabilities of a service
Define Tasks
Describe the steps needed to implement a feature

26. The application is slow or not very
responsive
The typical answer:
+ +

27. The Result:

Deployment
Patch Management

Troubleshooting

28. Guides adding the RIGHT instrumentation and
ONLY the instrumentation your application needs
Allows your IT Operations to identify and sovle
issues BEFORE your customer calls in

29. Application, Component,
Service or Dependency
Example:
Transport Order Application
Transport Web Service
Warehouse Management
Application
Arranged into a Logical
Hierarchy
Shipping Service
Transport Order

Warehouse
Management
Application
Transport
Web Service

30. Part of a Module that
an administrator would
want to monitor
Can only be in one
health state at a time
(e.g. green, yellow, red)
Example:
Configuration
Database
Security
General Functionality
Transport Order
Application
Configuration
Database
Security
General Functionality

31. Car
Engine
Transmission
Fuel
Mirrors

32. State of a Feature
Green – Aspect Functioning Normally
Yellow – Aspect is partially functioning but
at some degraded level
Red – No Service is being provided by this
Aspect
Detectors
Indicate the State of an Aspect
Performance Counters
Windows Events
Absence of Event
Example:
Event ID 24 = Server Not Found
Event ID 24 occurs

33. What impact does a Feature
have on its Module?
What impact does a Module
have on its Parent?
Example:
Because the connectivity of the
Web Service is Red, the impact
on the Transport order
Application is also Red.
However, the impact on the
Shipping Service is only yellow
because the Warehouse
Management Application is
green

35. Generate event logs for deployment!

36. Building applications by assembling existing
building blocks (aka services)
Over the internet
For end users (simplicity)
We see Microsoft Popfly as a kind of
Preview for future technologies

37. Building Applications with Popfly

38. Business today means being agile
Agility results in distributed computing
The nature of distributed computing requires
new kind of tools
Designing and Building
Deployment and Operations
Modeling and code generation is the next level
XAML will be a first class citizen
OSLO will be Microsoft‘s answers for these
challenges?
