Service Oriented Architecture (SOA) is an architectural model that provides a methodology and a working framework based on services. It can be very aligned with the business hence SOA is used interchangeably for business and for IT. SOA is a good paradigm which will enable new business challenges and to become more competitive in a faster manner. Furthermore, this architecture model will provide flexibility and agility, to respond to change quickly, cheaply and effectively.
The Server Labs recommends a tactical and iterative approach to the SOA implementation, as well as for the governance, and never to launch them in a big bang. The approach should start with a preliminarily analysis and sponsorship committee creation at management level followed by a selected pilot project, to proof that SOA is the right approach for the enterprise (in some cases, it may not be adequate). This pilot and the services just created will act as a baseline on top of which to define and develop the enterprise architecture in an iterative and incremental manner. This is why agile methodologies are appropriate for SOA. According to this approach, The Server Labs provides the following SOA services:

THE SERVER LABS´s SOA Centre of Excellence is our SOA specific competence centre to offer our clients expert advice during the launch of the SOA initiative, and during the implementation of projects under the SOA paradigm. The Centre of excellence is one of the first groups to be appointed at the beginning of the SOA efforts, together with the sponsorship committee. If your organisation lacks the resources and/or experience to put together such group, we provide our Centre of Excellence as a service. Our architects will apply their integration experience, software engineering skills and agile methodologies expertise to help and/or lead during the planning, analysis, design, development and governance of the SOA initiative. The objective is to maximise the ROI and the total value for the project. We will make sure that the integration project is aligned with the requirements specified by the enterprise architecture department. Being architects, we will obviously make sure that all architectural best practices and methodologies for SOA are enforced throughout the life cycle of the project.
SOA Methodologies
Current methodologies (e.g. Object-Oriented Analysis and Design (OOAD) or Business Process Modelling (BPM)) are not sufficient neither optimised for SOA. A new methodology has been created: Service-Oriented Analysis and Design (SOAD).
Similarly, for an SOA project to work out, it is very important to use a proper life cycle in the organisation. Waterfall is not that good for SOA, but a more agile methodology is required. The Server Labs is skilled and experienced in Agile methodologies and techniques for software development projects. |
