The Evolution of IT to SOA SOA Evolution Traditional IT Mainframe EAI SOA There is a stunning similarity between the global development of villages and cities and the evolution of SOA. We speak of the global village and internauts that live in social networks and travel on the virtual highway called internet. The enterprise IT of the future will be a virtual village. We can but learn from the many thousand years of political experience in adminstration and governance of villages. And every day there are surprises, you cannot control and predict everything

Why SAP is the most mature SOA Ready ERP package and yet our sorrow child

Producing Win-Win with SOA Marketplaces 12th June 2008 - Eindhoven

SOA is still a secret … 12th June 2008 - Eindhoven Many a vendor „sells SOA“ without seeming to know what they are talking about. There is hardly a software service provider or software vendor who does not speak about SOA and claims to be fully ready for it.

 Offers are immature, incomplete and mostly TOO complicated to use eSOA is Still Far Away SOA Award Contest 12th June 2008 - Eindhoven SAP, IBM, Oracle … they all offer SOA and are yet far, far away from a practible and usable architecture for running services efficiently in enterprises.  Offers are immature, incomplete and mostly TOO complicated to use The current situation of SOA offers for enterprise use is still not satisfying at all. All the big vendors jump aggressively the SOA band waggon but are yet still far away from anything that is worth to be called a viable and usable set of architecture components that would bring the values that are possible with SOA.

Why SOA? 12th June 2008 - Eindhoven Nearly all IT providers now speak of SOA. Do they really now what SOA means? Do we need SOA?

IT in ERP today is „vendor-oriented“ The capability of a product decides what to do with the software Recombination of features is nearly impossible 12th June 2008 - Eindhoven

SOA Saves 90% IT money A well established and company wide deployed SOA saves typically 90% of IT investment compared to classical implementations. 12th June 2008 - Eindhoven

Windows is Already a Mashup King We use Microsoft Office Or may use OpenOffice instead Use Ulead PhotoImage Use Browser from Firefox or Flock Destop Search from Google  Best of Breed Just Download, install  Run 12th June 2008 - Eindhoven Our modern PC is already a mashup place. Windows is the commonly used operating system. The success of Windows is not because it is the best operating system we could imagine; and it is not because anybody forced us to use Windows; Windows is the operating system standard, because it was the most attractive for both vendors and software users.

How enterprises learn from the success story of the WWW. Cape Enterprise 2.0 How enterprises learn from the success story of the WWW. Finally.

Enterprise 2.0 (3.0?) „Webification“ of enterprise collaboration Central Sharepoints for data Life Collaboration „You Tube“ for enterprises and life-cams Desktop-Sharing Enterprise Search Semnatic Web Wiki Libraries instead of directory trees Enterprise wide discussion forums ERP   Desktop Integration Application  Outlook

Enterprise 2.0 Learns WWW 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 havinjg changed our daily life. Especially Wikipedia demonstrated succesfully that communities can produce quality results without a monarchical control based on trust and competition.

Social Networks are on the rise Social communities like XINK, LinkedIn Stay in touch with business friends The big Mathematical brain: Matheon Best math genies form a new giant math brain Developer networks No OSS anymore  SDN is the place to go 12th June 2008 - Eindhoven

SOA is the groundwork for Enterprise 2.0 Enterprise 2.0 is based on collaboration Collaboration requires SOA Enterprises are not yet SOA ready … 12th June 2008 - Eindhoven

Enterprise Apps Become Services Enterprise Suites turn into Service Collections Enterprise Suites Service Collections 12th June 2008 - Eindhoven A necessity for a SOA success is a quick transformation of the functionality of enterrpise applications into a collection of services allowing the most important and strongest features to be reused by other applications.

What is SOA? Making sure that we speak of the same. „First confuse the words then the things“

SOA is More Than Middleware and ESB 12th June 2008 - Eindhoven The traditional middleware vendors did a great job in having their audience the impression that buying one of their product will pay for a full featured SOA. Unfortunately the truth cannot be farther away. But SOA is far more than just middleware or the implementation of an Enterprise Service Bus. Middleware and ESB are the communication layer They are the streets and code of traffic

SOA is the Marketplace for Services SOA Market Gover-nance Front-end Services Semantics Abst-raction Persis- tence Virtuali-zation Security& Safety Hard-ware Governance Frontend Services Semantics Abstraction Middleware Persistence Virtualization Security & Safety Physical Layer 12th June 2008 - Eindhoven SOA is architecture that allows a convenient addition, removal and exectution of servcies. In addition SOA shall permanently investigate the needs of service usage and decide if some popular service can be offered as public services centrally on top of the SOA marketplace.

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

SOA is the Service Marketplace SOA by nature is a service. SOA is completely useless without services. It is also useless if SOA does not help to make the service deployment and service execution as convenient as possible. SOA caters for an infrastructure and basic services to make the execution of services as convenient as possible

It is important to understand that the completeness of the stack is the essential, since every individual that operates in a SOA environment can expect the presence of any of the stack layers and promoted services.

How to Get SOA? The administration and development planning of cities are the role model for SOA governance.

Secret of Success in a Society lies in producing Win-Win-Situation 12th June 2008 - Eindhoven Visible Wins … not hidden wins

EAI SOA Evolves like a City SOA Evolution Traditional IT Mainframe EAI SOA There is a stunning similarity between the global development of villages and cities and the evolution of SOA.

In the beginning …. there were isolated habitats That was inefficient Every farm autonomous Water, nutrition … all supplied by themselves That was inefficient 12th June 2008 - Eindhoven In the beginning, when humans started settlements they built isolated farms. Every farm

Then habitats started sharing services Common fountain Farms specialiing in meat OR crop Expert services were created Schools, smiths, waggoners, carpenters, bakeries … One town wall protects everybody 12th June 2008 - Eindhoven

Challenges of Interacting Societies 12th June 2008 - Eindhoven Freely interacting agents create an uncontrollable form of complexity

Oligarchy cannot cope with complexity 12th June 2008 - Eindhoven

How Do You Control Complexity? How to control the crew of a ship? How to you control an army? How to govern a city? How to you control China, Zimbabwe? 12th June 2008 - Eindhoven Knowing about complexity does not help us further. We have to understand how we can cope with the challenges of a new complexity. `Lucky we are, that situations of many to many interactions are not new in this our world. Indeed, we encounter complex (this means: non linear) situations of interaction every day and in every level of our human societies. Why wouldn‘t we ask ourself if they ways how those societies cope with their complex livings give us some proven concepts that we can adopt for our own necessities. How do you control a project team of 50 people? Does it really work that you tell them what to do and what not to do - and then it all works? How do you control the crew of an ocean liner? How do you control an army? How do you control a company with 100000 employees? How do you control a country like China? Over 1000 Millions of people? Is it really law and order? Why does then law and order not work in Iraq or Zimbabwe?   For project teams the standard recommendation used to be standardized plans that were called "roadmaps" and looks like a "waterfall" in a typical GANTT-Chart. In fact, such phased plans are based on the assumption that there is an inherent and natural linear cascade of dependencies. Especially the waterfall technique ignores notoriously the possibility that an action at a certain moment of time may reverberate back to previously completed action and invalidate the precondition that was the basis for the cascade. Since you typically cannot control every behaviour at any moment of time of a group of people (or another group of independently acting objects) a waterfall plan is normally useless in real life.

Waterfall Doesn‘t Meet Complexity Waterfall method imply linearity Waterfall ignores that action may reverberate to earlier conditions Waterfall is not agile Waterfalls imply deterministic scenarios and linearity Waterfalls ignores that actions may reverberate to earlier conditions Waterfalls are not agile They cannot cope with uncertainties 12th June 2008 - Eindhoven The classical waterfall method is designed for purely linear, deterministic scenarios. In a SOA and Enterprise 2.0 we hardly find situations where we can tell easily up-front with certainty how the consequent action will look like. Since waterfall requires pre-determination of consequnece a waterfall project method cannot cope with feedback cicles, with uncertainty, and is therefore not agile. Waterfall is therefore no choice for the challenges of Enterprise 2.0.

The Paradox of Uncertainty 2-body Theorem A satellite revolves in an exact elliptical path around it gravitational center point. 3-body Theorem There is no elementary mathematical formula to calculate the paths of three body that interact with each other 12th June 2008 - Eindhoven Uncertainty hits us at palces where we do not expect and where our alleged common sense rebels. We all know from physics that a planet takes an elliptical orbit around a central star. There is a formula well described by Johannes Kepler that lets us calculate the position of the planet in the orbit at any given moment of time. Unfortunately this is a purely hypothetical constellation. In reality there are far more gravitational fields that may influence the motion path. And now a paradox of uncertainty hits: if there are three freely interacting bodies then there is no mathematical deterministic formula to calculate the exact positioon of all the three bodies.

How do you control planets‘ motion? Planets are controlled by gravitation. Gravitation produces a focal point. Gravitation means attraction. 12th June 2008 - Eindhoven Let us ask another questions far wider than the widest of our horizons. How do you control the movement of planets? Again we have an example of mutually interacting but independent objects. Thrown into the void the planets would make them move without a plan and in complete chaos. But there is a magic that makes them move in celestial harmony: gravitation. Gravitation is the point of attraction for the planets. And this leads as to the spur for the secret of true control in interacting systems: When it comes to the question how to control complex systems the strategy is to build up a focal point of attraction. gravitation

Attraction controls communities Enterprises are communities Attraction may be More money, less costs More creativeness More fun and joy More productiveness Better quality Creativeness Fun and joy Produc-tiveness Quality Money 12th June 2008 - Eindhoven
