1ARCHITECTURE PLAN TO USE SERVICE ORIENTED ARCHITECTUREArchitecture plan to use service oriented architecture:In order to have a clear view about the service-oriented architecture and plan accordingly, itis effective to divide the infrastructure in terms of layers that helps to analyze the architecturalprocess more intuitively and accurately (Erl, Marson & Stoffers, 2017). The layers can bedivided broadly into three categories:Operational layer Enterprise layer Services layer According to the authors, it is important to review each layer wisely as certain decisionregarding design and architectural plan has to be made at every layer the design goes through.Operational layer:This layer usually deals with application that is custom built. These applications are alsoknown by legacy system existing in practice (Serrano, Hernantes & Gallardo, 2014).Applications, built with CRM and ERP package are also managed in this layer. The layer alsoincludes implementation techniques of object-oriented system and applications that providebusiness intelligence. According to the authors, this particular layer plays crucial role in thearchitectural planning as it helps to integrate the existing systems with service-orientedtechniques.Enterprise layer:
2ARCHITECTURE PLAN TO USE SERVICE ORIENTED ARCHITECTUREThis layer consists of tools that can be used to realize the functionality and maintain thequality of the deployed service. These tools are managed using well-tailored governance policiesthat are specially designed for custom needs. This layer is responsible for better management ofthe System Level Architecture, which in turn ensures the better adoptability of the serviceoriented architecture for the organization (Erl, 2015). The typical technologies that are used at this layer are container-based which includesapplication servers, which helps to manage the components specially designed for service-oriented architecture as suggested by the author.Services layer:The layer consists of services that are chosen by the organization and funding related tothose services is included in this layer. The services may be static waiting for invocation or theycan be identified with proper techniques (Hurber et al., 2014). As the authors suggested, this layer is effective to ensure the quality of services for theoverall system. The mechanism through which enterprise level components are managed belongsto this layer. Detailed approach for architecture modeling:The design of service-oriented architecture can be classified into three key aspects calledidentification, specification and realization of services (Biehl et al., 2014). Identification of services:To implement the architecture that is service based, identification of the services is of prime importance The process is executed by combining the top-down, bottom-up, and middle-
