Four key points of SOA Implementation

Global planning

There are many technical factors in the implementation of SOA. As a user, you need to select appropriate tools and professional technical talents. As a user, to implement SOA, you must first make a comprehensive assessment of your system, understand how much your existing system can use, how much you need to transform, and what new systems you need, how can your system meet your needs in the future, and how much capital you may invest in the new system. In short, there must be an overall plan, which is also the most fundamental step for implementing SOA. Secondly, select appropriate tools and technologies. The system, the platform, and the system to be transformed need to be implemented step by step. In this process, the products selected must be different. Finally, it is the development process. Development is also a process of learning and practice for most users.

　　Requirements to be calculated

The method for evaluating an SOA project is different from that for evaluating a traditional software project. SOA shows its advantages in the enterprise through various channels. SOA optimizes business processes through shared services and makes comprehensive innovation possible. Its "value opportunities" far exceed traditional software projects. To build powerful business instances, implementing business innovation through SOA is an important watershed. It must be recognized that early investments in building SOA projects will produce significant benefits that will become increasingly apparent over time.

Bea believes that the specific implementation progress and capital investment of SOA depend on the accumulation of IT applications by enterprises and on the target layer of SOA implementation. To help enterprises understand these situations, Bea provides the "SOA preparation status evaluation tool"-a web-based online tool, it helps CIOs plan SOA component adoption and benchmark testing to determine how to migrate most effectively to a more adaptive it design and infrastructure. After you use the beasoa preparation status evaluation tool to find your specific needs, you can start your SOA journey.

　　Select products and solutions with caution

Bea believes that users should consider the platform selection, implementation methods and approaches, and supplier selection when selecting SOA products and technologies. When selecting a software platform, you must first consider the openness and standard support of the platform. In terms of implementation methods and approaches, BEA has summarized the Six-segment methodology based on previous successful experiences and divided the factors that affect the successful implementation of SOA into six aspects: business strategies and processes, infrastructure, construction modules, projects and applications, costs and benefits, and planning and management. When implementing SOA, CIOs should consider these six factors comprehensively. The implementation of SOA involves the adjustment and change of the entire enterprise's IT systems and business processes, which is inseparable from the corresponding consulting and professional services. Therefore, when selecting a supplier, we must first check whether its products meet the actual needs of the enterprise, whether there are many successful application cases, and how the existing customers evaluate it. Secondly, we also need to carefully examine the professional service capabilities of suppliers, whether they can help users analyze the enterprise's it status quo, and put forward constructive comments.

Bea believes that for enterprises, adopting SOA will not increase the complexity of managing IT systems. Bea strives to protect mainstream middleware technologies, such as J2EE and CORBA, and has accumulated a lot of practical operation experience to protect enterprises' IT investment in the past.

　　To stand and run fast

An enterprise deploys an SOA platform just like a city for city planning. During this planning and construction process, unreasonable streets need to be rebuilt and packaged, there are always old residential areas that need to be demolished, demolished and rebuilt, and new buildings need to be constantly built to better meet the pace of a city's advancement. The same applies to SOA for enterprises. systems that are too outdated need to be retried. systems that can continue to be applied need to be packaged and improved, while some new systems need to be re-planned. At the same time, after the establishment of the SOA platform, it is easier to implement the planning of a new system. Moreover, even today, even if a system built on the SOA platform is applied to enterprises continuously, the system may be unreasonable and need to be adjusted again.

It is impossible to complete the implementation of SOA within one day or make a decision today. At present, many users have radical ideas, which is unrealistic. SOA implementation starts at the department level. The soul of SOA is that it allows users to build a loosely coupled platform, which is also the key for SOA to attract users. However, SOA will not be implemented overnight. SOA planning, implementation, and service are a process.
