Su has written such a couplet - tea, tea, the tea; sit, sit down, please sit.Expression is that when a person twists and turns to reach your house, you respect his feelings gradually arises spontaneously, the very beginning you feel this person is very common, in the end you find that this person is expert.SOA with a pair of couplets to describe the situation in the global development is really appropriate.
Facing maximize the return on IT investment
July is winter in Australia, but organized by the BEA, "Asia-Pacific media and analyst summit" on the topic of SOA is hot.Although for SOA and many of the arguments, 但 more and more people begin to believe - companies need about is service Wei cores are up infrastructure, and service-oriented architecture (SOA) has been from the Shi Yan phase Jinruliaodascale implementation stage.
Why is this situation?Existing IT enterprise architecture, what problems arise?
Not long ago, in the "new think tank" held a salon on corporate information, the Nvi collaborative technology general manager, Mr. Shen Sheng Wen indicated his company's CIO has served as the Great Wall when a deep feeling.In his view, software development is a complex process, the front part of the demand is assumed to be sufficiently accurate to do so.In fact management is a very complex environment, which constantly change.Curing the framework of the original management and managed to move closer to reality when there is a conflict, will be acclimatized.At the same time, the needs of enterprises must be individualized, personalized software vendors to move closer to the course, paid a heavy price.The individual and common difficulties of the conflict have become the main reason for China's enterprise information.
Actually, the problem is far more than that, a few years ago, many Chinese enterprises in response to the government's call to follow suit with the mentality of mischief - competitors are doing business with the industry of information technology, so we also have to do such a thingso outdated; while Chinese enterprises in the information needs of their early expression is not clear, causing many companies on the IT investment is blind, almost every subsystem independently, as one by one "information island", and the resultingmany problems: one is difficult to reuse IT assets, resulting in waste of resources; the other is the information not be shared, such as a subsystem of the data used in other systems if necessary, we need to repeat the acquisition; The third is the lack ofenterprise IT and business operations of the overall monitoring, there is no uniform view, it is difficult to make the right decisions.
These problems are a headache not only to enable enterprises to CEO, CIO were also brought to the enterprise big challenge: how to full use of existing IT Zichan and new technical, planning and implementation of IT system that gives the best to meet the business needs changefor business operations to provide the best support to ensure companies maximize the return on IT investment?
BEA Au-Yeung, general manager of Asia-Pacific region told us to meet these challenges, rely solely on traditional IT technologies and system architecture is not enough, CEO, CIO who must seek new technologies and new program support.To solve these problems, enterprises must establish a flexible, rapid response to customer support infrastructure, it's Ying Yong Ke Yi inclusive Xianyou and Manzu future customer needs and business requirements.
This is the service-oriented architecture (SOA) foundation for the birth and development.Building SOA is a way of enterprise software architecture, its basic idea is to service the core business of IT resources will be integrated into a useable, standards-based services and applications so that it can be reassembled.Compared with other enterprise architecture, SOA for IT to become more flexible, able to respond to business needs faster and thus achieve better operational flexibility, enabling enterprises to rapid change on an effective response, and use changescompetitive advantage.
Implementation of the SOA can be fully retained past IT investments, by establishing a system to shield the complexity of the underlying infrastructure for the free movement of IT assets to build a base platform.Then, the original system, all packaged into a service business functions, and the requirements based on business reorganization, Zuizhongfuge the business system into a new, Conger rapidly meet new business needs.
In seeking a balance between management and technology
From this, SOA seems to be we now have multiple IT applications to solve the system under the situation where many the best solution.However, the key issue is that we in the implementation of SOA will not appear in the past when companies encounter when implementing information technology problems?The previous process, the software company's technical staff are good at technology, not good management, and enterprise managers are good at management rather than technical.
So the design of SOA based on what is it?Enterprise in the implementation of the process they should pay attention to it?
General Manager Asia Pacific at BEA seems to Au-Yeung, SOA is not really a product, not a pure technology projects.It refers to a more service-centered design framework is a concept, but also a methodology.This is like it inside the IT big or small particle size can be distinguished, and can control the various elements of packing up, packing it beyond the way a service outside exposed, that is, between all the systems can beexchange, call each other to make the world of IT to the level of the various elements being connected together, this is a connotation of SOA itself.In other words, in addition to the infrastructure in place, the management is a very important aspect, if you want to manage, then it must adopt a uniformity and flexibility in the balance between the need to reach, "I think the emergence of SOA isin IT technology and IT management on how to strike a balance between the importance of thinking, a new architecture. "
A senior IT person once said: "If the software company is not selling products, but to improve enterprise management level. Managers do not use technology ideas into the information, use management thinking to solve what they want. "Indeed, information theory is the scope of modern management, the core of management, not technology.The concept of core management products, management involvement, management language, rather than technical language, the only way to form executable information system.
Therefore, the right businesses, the successful implementation of SOA is not just a technical issue, it involves strategy, business model, organization, business processes and even corporate culture and many other management issues.
During the "Asia-Pacific media and analyst summit" on a BEA senior manager admitted, to help customers implement SOA in the process, the first problem encountered is the management, followed by communication and collaboration, and finally technology.BEA appears in the latest release of the SOA solution must include three core elements, they are - platform, practice and people.
