Marketplace SOA brings uncredible wins through collaboration Thursday, 27 June 2019 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.

Thursday, 27 June 2019 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.

Collaboration will bring SOA 90% wins Thursday, 27 June 2019 Collaboration will bring SOA 90% wins 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.

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.

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. http://docs.google.com 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.

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.

„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  www.jingproject.com Desktop-Sharing  http://www.mikogo.com Enterprise wide discussion forums instead of email News tickers Axel Angeli - (c) 2008 logosworld.com - Building the SOA City Thursday, 27 June 2019

Collaborative Web What Advantage Brings the Collaborative Web? Traditional IT Directory Trees Owner can edit Static hierarchy Information Tree Life Collaboration Redundancy Version anarchy Manual notifications Email communication Only peer communication Results only actively shared Data hidden in vaults Enterprise 2.0 Wiki Libraries Everybody can edit Associative via categories Information Clouds Central Data Sharepoints Life access Central versioning Rule-based notification Forums Everybody can contribute Results are public by default Easy finding with Search engine Axel Angeli - (c) 2008 logosworld.com - Building the SOA City Thursday, 27 June 2019

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 Email data to a service that will post the data This is known as “blog by email” or “MoBlogging” for mobile blogging

Example: Document distribution Select sales orders and drawings from a database Display data as web page Select results from Web page email them as ZIPped PDF and/or XML, Word Archive the produced result as attachment to CRM PHP, Ruby can do Built-in email 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!

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 Axel Angeli - (c) 2008 logosworld.com - Building the SOA City
