2. What is SOA? SOA Market From Waterfall to Marketplace Front-end
Services
Abst-raction
Persis- tence
Virtua-lization
Security & Safety
Net-work
Hard-ware
From Waterfall to Marketplace

3. SOA is an architecture … and it has a goal:
Free humans from doing the same work over and over again!

4. SOA caters for an infrastructure and basic services to make the execution of services as convenient as possible

5. Thinking different
The important thing in SOA is not so much to obtain new technology as to discover new ways of thinking about them.

6. SOA is Next Generation Client-Server
SOA is based on components (=services)
SOA provides basic services built-in
E.g. Conversion, printing, routing, security
SOA allows plugging new services
Active plug and unplug new features
SOA provides communication
All communication on official routes only

7. SOA is Event Driven Architecture
Saturday, 13 July 2019
Components are not activated
Components act on events
„You call help, and someone comes to rescue“

8. SOA is Components Based Architecture
Saturday, 13 July 2019
Components are loosely coupled
No hard-coded links between components
If COMP1 needs to Call COMP2 it needs the help of a COMP3
Allowing free recombinations
Allowing reuse of components
Program flows are separate from services
Axel Angeli - (c) 2008 logosworld.com - Building the SOA City

9. SOA is like a city Clients (Citizens) Servers (Business, Shops)
Communication Services
Channels (Streets)
Transportation proxies (Bus)
Monitoring (Police)
SOA evolves gradually – like a city

10. SOA encourages … SOA encourages use of standards
But it does not make them mandatory
SOA encourages best practices
By making them easier to use than bad practices

11. SOA has been there since the early days of computing

12. Johann Wolfgang Goethe
Every bright idea has been thought of before, you only need to try thinking of it again.
Alles Gescheite ist schon gedacht worden, man muss nur versuchen, es noch einmal zu denken.

13. SOA Is Not New SOA has been there since the early days of computing
Operating Systems Are Early SOA Implementations
BIOS Are Service Frameworks
They cater for services in repeating tasks
Printer drivers
Screen outout
Mouse, Windows, Drawing, Network etc.

14. SOA Is Services and Architecture
Orchestration
Common Runtime
Message Flow
Services need Architecture
Architecture needs Services
