SOA Marketplace: 90% ROI?
Marketplace SOA brings uncredible wins through collaboration
SOA is able to free up to 90% of current IT costs due to efficiency boost
Axel Angeli - (c) 2008 logosworld.com - Building SOA City
There have been the good old times of computing. The times when you wrote a program with several hundreds lines of code, punched them on some punch cards and turned them in to the operator to get it executed sooner or later. In today‘s understanding it was certainly later, since it normally took several hours to get such a batch of cards processed.

Enterprise SOA
Introduces the already succesful concepts of the WWW - with search engines, online markets, life communication, service sharing and much more – within the closed habitat of an enterprise.
Axel Angeli - (c) 2008 logosworld.com - Building the SOA City
For years there is a perpetual fuzz about the term „Enterprise SOA“. Since multi-national enterpises are the primary prey of the commercial software vendors, they have soon found the new hype about the foundament of the WWW could serve as a vehicle to bring their own software developments to a market. Enterprise is nothing but the attempt to introduce the principles that made the success of the WWW within the closed boundaries of islandish enterprise structure.
The idea behind Enterpise SOA is simple. The WWW has shown that a completely new form of efficient computing arises if a enormous large number of indenpendently acting agents start cooperating with each other. It is the freedom of a market that produces a new efficiency and far higher quality of computing when computers share and exchange services with each others.

Axel Angeli - (c) 2008 logosworld.com - Building the SOA City
Queues is it what rule our daily life. Queues help avoiding permanent contention and define default rules on who may move first and who next. At the grocery, at the doctors, climbing a bus: you always will find queues to access the service you ask for. Even waiting at a traffic light to turn green, you have a queue; in fact streets are queues since they allow you to park or halt your car if the segment you want to enter is not free.
Queue processing is the solution path to house-hold with limited resources. If more batch requests come in than there are processing slots available, you need to find a way to process them without contention. In other words: if a crowd wants to enter the bus through one door at the same time, nobody will eventually come forward.
Queues explicitely and deliberately retract the rights to choose a processing resource from the calling process in favour of a managed assignment of resources by a central managing dispatcher. If you have acloud of computers, your dispatcher will choose the individual CPU to use, and not the requesting agent.
Queue also allow putting priorities. E.g. you can always keep one process free for some short running emergencies processes.

14. Difference between Enterprise and WWW
Thursday, 27 June 2019
Enterprise is
Negotiate, negotiate, negotiate
WWW is
Collaborate, collaborate, collaborate

But we can learn good lessons from this procedures. When we analyze the simple process of turning in punch cards to get them processed we are able to identify a number of concepts that we shall re-encounter later in the context of a service oriented architecture.

22. SOA Follows Same Evolution as Industries
Thursday, 27 June 2019
Early Medieval Guilds
Success with specialization of city life
Automotive
Example: Henry Ford, GM
Success through component manufacturing
Electronics
Examples: TV, PCs
Success through module assembly
Microsoft Windows
Success through DCOM (components)
Axel Angeli - (c) 2008 logosworld.com - Building SOA City
It is a similar development that we have learned from other industrial sectors. It started in the medieval times when cities where formed from isolated farms and the common tasks were distributed amongst the citizens, leading into a society of specialists.
Later we invented cars and soon their assembly became so complex that it became difficult to find causes of malfunction and repair them. Then Henry Ford found out that building cars from specialized components gave a higher overall throughput and led into a higher quality of the finished merchandise.
Many years later the same procedure took place when electronics became more and more popular. We may remember the TV sets of the 1960ties years that soon became so complex that every repair might have taken hours to fulfil. Then industry soon started building the TV sets from modules. This reduced the costs of manufacturing a single TV set when doing mass production, enhanced quality and made repair fairly easy and quick by simply replacing the malfunctioning component.
And then the times of the PC came. It was all easy during the times of DOS but then the use of PC became more and more challenging. But soon programs became so complex and loaded with features that it was mandatory to break down the programs in smaller components. Adding a unified component interface convention led then into the DCOM infrastructure which is now the basis of all Windows programming. Linux offered a similar concept with their CORBA logic.

How enterprises learn from the success story of the WWW.

29. Enterprise 2.0 Learns WWW Enterprises adopt the succesful WWW
Thursday, 27 June 2019
Enterprises adopt the succesful WWW
WWW is based on services
WWW is a grown SOA 
Learning from AMAZON, Google , XING, Wikipedia, eBAY, YouTube et.al.
Enterprises finally understand the benefits of adopting a great some of the succesful concepts and services that have become daily routine for the users of the WWW. Google. Amazon and Wikipedia should be given the merits of having changed our daily life. Especially Wikipedia demonstrated succesfully that communities can produce quality results without a monarchical control based on trust and competition.

30. Service Examples Google amazon.com SAP
Google
amazon.com
SAP
No friendly name! No usage examples!
You see here some examples of wev services provided by the big SOA proponents Google, Amazon and also SAP.
The Amazon example displays the web service description as XML (WSDL) and also a small example of how a request can be made without doing more than typing the URL in the command line.
The same works with a SAP system where you have authorized access to.

31. „Webification“ of enterprise collaboration
Central Data Sharepoints
CMS
WebDAV-Enablement
Enterprise Search
 Google Appliance
Wiki Libraries
Replacing directory trees
Semantic Web
Intelligent DMS
ERP   Desktop Integration
Application  Outlook
Life Collaboration
„You Tube“ for enterprises and life-cams 
Desktop-Sharing 
Enterprise wide discussion forums instead of
News tickers

33. Example: MoBlogging
Simple Requirement
A travelling salesman enters service data into a local database
The data needs to be synchronized with the central CRM database
Classic Solution
Copy data to a workstation
Upload data
A better solution
data to a service that will post the data
This is known as “blog by ” or “MoBlogging” for mobile blogging

34. Example: Document distribution
Select sales orders and drawings from a database
Display data as web page
Select results from Web page
them as ZIPped PDF and/or XML, Word
Archive the produced result as attachment to CRM
PHP, Ruby can do
Built-in
Built-in PDF, ZIP etc.
Word conversion by .NET
SAP, Oracle ???
Solution:
Let ZIP do the ZIP
Let Acrobat do the PDF
Let .NET build the Word document
Endlessly complicated!

35. Example: Document Management
Thursday, 27 June 2019
Classical client server case
Classical Printing
Server extracts data to print
Data is sent to print server
Print server creates pixeled output
Disadvantage
Multiple redundant layouts
Redundant technology skills
Printer coordination needed
Explicit Printing via Service
Extract data to unified XML format
Send data to XML formatter
Formatter creates pixels
Advantage
Clients share same resources
One form design
One central print control

38. Collaboration Needs Infrastructure
Thursday, 27 June 2019
Collaboration works on infrastructure
Sharing common tools and services
Standards alone do not help
The are simply not abided by
People do not read monster docs like EDIFACT
People do not even read project guide lines
Convention grows through convenience
Ready usable services mean convenience
SOA offers convenient services
That is why we need SOA
