Only from a cost / benefit analysis up to lobby, in popular parlance of some, that is, to show how enterprise SOA can help enterprises "save money" or to help businesses "make money."
SAP has just attended the annual market launch of the general assembly ears still echoed the theme of those brilliant speech. All the lectures are delivered with a message that SAP will work hard in 2007 to promote NetWeaver platform and my SAP ERP 2005 application, of course, the content of speech have tried to answer "Why use enterprise-class SOA? "The whole theme of the conference is" Believe it, Achieve it ", so it would like to have to talk about some ideas.
Each enterprise are rational economic man, the basic logic of the decision-making are based on cost / benefit analysis (Cost / Benefit Analyze) above. Enterprises should choose enterprise-class SOA, only from a cost / benefit analysis up to lobby, in popular parlance of some, that is, to show how enterprise SOA can help enterprises "save money" or to help businesses "make money."
First to say "save money"
Enterprise Information Management is now the most expensive work? Most of the information will be thought of in charge of Information System Integration (Enterprise Integration). This is in the enterprise mergers and acquisitions (Mergers and Acquisitions, M & A)) especially when, while the M & A seems to be increasingly become a trend. In 2005, a market study, nearly 200 information executives, 76% confirmed that his company has been or will be carried out M & A. Has been completed in the M & A firms, 70% considered the results unsatisfactory, because the unexpected complexity of heterogeneous information systems integration issues delayed the merger of the business. To do this using a standardized framework to integrate your information systems, this is the best use of enterprise-class SOA reasons. In two ways, on the one hand, if you have completed the M & A, do the decision-making information system integration, select the enterprise-class SOA, after all wise; the other hand, if prepared to do M & A, the existing information systems to migrate to Enterprise SOA, is to preserve and increase investment in the future. Whether the entire application system upgrade to support enterprise-class SOA version, for example: mySAP ERP 2005, or use the information to support enterprise-class SOA platforms, such as: SAP NetWeaver, for existing applications to provide SOA interfaces, it can preserve the existing investment based on the "evolution" to the new structure.
Although, now there are about 3 / 4 enterprise-class SOA project is to do information system integration, but in the long-term trends, to provide enterprise-class SOA Software Reuse (Re-use), better able to provide you province. "Reinvent the wheel" thing, in the enterprise information system is not uncommon, for example: with a credit inquiry function, because to be using a different application systems in different departments for different systems to achieve the same function, respectively, technology platform different interfaces. To this end, design, development, testing, maintenance, and so the workload may be as different technology platforms into a doubled and redoubled. The standard enterprise-level SOA interface is a once and for all alternatives. Well, now why reuse is not widespread? Imagine you want to define a wide range of reusable services can be not an easy task. Requires not only high-quality code, but also needs a stable interface, the appropriate application functionality granularity. The need for business processes at the same time grasp of both macro and micro: macro security services to be consumed to grasp the larger environment, ensuring interface stability; microscopic understanding of business processes, decision applications particle size, too small and functional damage to the performance (Performance) , while the excessive division of the expense of flexibility (Agility). To this end SAP's Enterprise Services Knowledge Base (Enterprise Service Repository) in the definition of services that make a example of a sample.
Talk about "making money"
ZSM Net editor in September last year, and Dan Farber in a dialogue on innovation, our executive director XIA Xi (Indarjeet) said: SOA is not a fashionable XML technology, in order to achieve a flexible business model, with a flexible business model, when you see new opportunities, can quickly become a new business, and let your information systems to support it, so that technical superiority quickly into a strategic advantage; when the tide of SOA formed, it will not be able to leave a business it is to survive. Enterprise SOA, "making money" effect is the flexible application system (Flexible Applications) to provide fast response to business innovation and product sets to help companies realize rapid differentiation competitive strategic advantage, so that "superfish" eat "slow fish."
In addition, enterprise-class SOA, "making money" effect is also hoped that through a standard low-cost integration of interface, access to a broader market. For example: a large courier company, the express orders of the SOA interface to be open to a large number of small-scale applications providers to integrate online delivery orders, virtually express delivery company to infiltrate small-scale applications to small business users. According to popular saying, that is, through the market's "Long Tail (Long Tail)" effect of money.
With these "save money" and "making money" reason, is not able to resolve your information platforms and applications to use enterprise-class SOA evolved out?
