Standardized, mainstream technologies, that are familiar to CSPs, developers and administrators, are the key to acceptance, ease-of-use and matching competence at all levels, as Petri Jarre and Roland Meyer of OSS Business Line at Nokia Siemens Networks explain.
‘We use Java for our Open EMS Suite because it is so open and allows for a range of developer competencies. It is also highly portable and not tied to any proprietary operating system or any specific environment, so in principle you can run the software on anything from a mainframe to a laptop’ says Petri Jarre, Product manager of Open EMS Suite. ‘And, because it is so commonly used in the open source market there are many reusable components and functionalities that can speed up the development process. It’s also surrounded by a vast and lively ecosystem which can take software development into different areas, make it better or shorten your time-to-market.’
Java has a clean structure with agreed interfaces and tools which guide the developer. It means that it’s almost always guaranteed that software will run true first time.
Just as Java is now standardized and mainstream these days, so too is Linux, the low cost of ownership operating system that Open EMS Suite run it on. It means that it is commonly used and is familiar to CSPs and the administrators at customer sites. This familiarity extends to the Java technologies and the Oracle databases used too.
‘From a middleware point of view this is ideal’ says Roland Meyer Senior Specialist, Software Architecture ‘Because of the huge systems that we support, we need software that is established and relational databases like Oracle that can scale and offer performance. An example of how these technologies come together is our portal. Based on an open source framework, integrated to the Java Enterprise Edition, it is very easy to add content because the framework is commonly used and supports the development of web-based user interfaces. If you want to bring additional content to the OES main screen, for example a new Performance Management report say, it is easily accomplished by developing portlets using these common technologies.’
To sum up, Nokia Siemens Networks aims to reduce risk and speed time-to-market by using proven architecture and mainstream IT technologies. Server side functionality based on J2EE with development tools (SDK) based on Eclipse the leading open source Integrated Development Environment. Programming interfaces are based on standard technologies, Java/EJB, XML and SQL, while the GUIs support both Java rich clients and web. The benefits are enormous. These technologies are already known to IT and software professionals allowing a short learning curve. They are supported by multiple vendors and provide freedom in the choice of underlying middleware, operating system and hardware.
