Popular from 2005 to the present, SOA, service-oriented, reusable component and so on have been widely accepted. All industries have some of the more successful cases, such as the Little Sheep restaurant industry, logistics, etc. Nanjing Tanker Shipping. But overall environmental point of view, SOA is still know many people, using fewer people. What are the barriers to the SOA practice of forward step?
Awkward one: No Requirements
In recent years, despite the fervent speculation SOA concepts, but the CIO's response was very calm. Sinochem Group, Jin-Song Peng, general manager of information technology, CIO has explained the selection process: "First of all, have business needs. The existing IT architecture can not meet the company in the operation and management needs. This time we will consider the transformation upgrade our IT systems. and then we will consider the idea of what technology is more suitable for us. This is our selection of logic. "
SOA's greatest advantage is that the service component of the interactive capabilities and heterogeneous applications. However, the advantages of SOA, not easy in the beginning reflected. Some enterprises in the initial deployment of SOA, it will reduce efficiency. This is because SOA need to reform the old system, need to sort out business processes, enterprises also need to train staff to enable them to adapt to the new IT systems and operating rules.
Therefore, when companies can some other more simple means, to meet business needs, they will not consider SOA. China Pharmaceutical Group Leiwan Yun, deputy director of the Ministry of Information told reporters that their current approach is through the implementation of ERP, a unified platform for resource management. Based on this platform for business analysis and decision making.
"SOA is too complex to implement, relatively high demands on the system. In some local systems may be loosely coupled with the SOA of this form, but the Group level, we currently do not have such intention." Lei Wanyun said.
Embarrassed 2: There needs to integrate the system less
If China Pharmaceutical Group because it is not driven by business needs, while "SOA" is not cold. Capital Window is then faced with the embarrassment of SOA effects can not be maximized.
Capital Window Zhe Wang, director of management and operation told reporters that the end of 2004, they discovered the concept of SOA, and soon, they encountered the opportunity to implement SOA. So they consider SOA to carry out small-scale trial.
"It was just a chance encounter, the Beijing Municipal Supervision Bureau to do a political fashion style hotline system, which is actually an online platform for the network to report complaints. When we started the traditional way is to do a version, but are not always effective, so when doing transformation, consider that the concept of SOA can not be used. "Zhe Wang said.
But at that time almost no mature SOA solution. Capital Window combing business processes, or through a British company a performance appraisal software, a feature to achieve.
Next is the business model. Capital Window domestic manufacturers have chosen a family to do the job, spent a half months, the flow chart of Capital Window made before, exactly the same tools to copy to the system. System on line in 2006, stability, strong, and now basically have not done too much change, nor any problems.
"But we were smaller, although more than three years on the line, but can integrate some or as little. Therefore, the greatest advantage of SOA, we are here and not fully displayed." Zhe Wang said.
Embarrassment 3: There needs can be more difficult to plan an integrated system
SOA in practice the most embarrassing things than there is demand, there is need to integrate the system, but it stuck in the IT planning. China Petroleum & Chemical Corporation on the face of such embarrassment.
Sinopec's system very large, very complex, change is more, it's useless SOA. But Sinopec also have their own distress.
"The following group of eight 90 units, with oil, refining enterprises, research institutes, construction units, distributed throughout the country, and even spread overseas. From the internal perspective, there are financial, personnel, IT, auditing many sector. precisely because it is too complicated, so do be very careful IT planning, for fear the whole thing thought to have negative consequences for business. "Sinopec deputy chief engineer of the Department of Management Information Systems, said Wu Zhenghong.
In addition, the overall SOA plan to do, but also face the embarrassment of the time. Sinopec, as such a large system, top-down planning at least a year or two. Upon completion of such planning, many businesses have changed. The result took a long time Gaode almost can not planning to use the.
"We track the SOA for a long time, and information to many manufacturers do. But no one can give us a complete answer. SOA practice also need to explore our own. Therefore, the whole IT system, we dare not major, because We have not thoroughly understand the SOA. "Wuzheng Hong reflections.
