Processes for Enterprise Application Architecture Management

Abstract

Over the past few decades, the way in which enterprises have performed their business and organizational changes at the level of information systems has for the most part been incomplete and / or unsystematic. Fundamental IT innovations have therefore coincided with the development of heterogeneous application landscapes which are more or less inconsistent with the business and / or process architecture. Explicit management of the application architecture, which forms the interface between the business and the technical view on the information system, is necessary to recreate and preserve consistency. Based on a requirements analysis for enterprise application architecture management and a discussion of related work from literature and practice, this paper proposes processes that are based on three case studies. The proposed processes are evaluated in respect of the specified requirements. Requirements management C-I Architecture development C-II C-IV Architecture conformity check Architecture communication C-III Define IT strategy C-I.1 Record operational requirements C-I.2 Communicate architecture artifacts C-IV.1 Check architecture conformity of projects Use existing architecture artifacts C-II.1 R5 R10 R5, R6 R5, R10 Identify need for action for the architecture C-I.3 R8 Evaluate need for action C-I.4 R4, R6 R5 Develop/adapt architecture artifacts C-II.2

Automation Processes for Enterprise Architecture Management

“…Therefore, this work provides a more detailed process and discusses implementation issues of automated EA maintenance. The work of Hafner and Winter [24] proposes a process for application architecture management. In their work, they take the application architecture management processes from three different companies and compare them with their requirements for managing application architecture.…”

Portability in the Enterprise Applications

“…Resource like text, JSON, XML of different representations is used by REST. Among that, JSON is the most popular one [9]. Node JS: Node.js is a runtime environment that permits writing back end applications in JavaScript.…”

Enterprise architecture governance

“…One of the consequences of the traditional approach to host all kinds of architecture management in the IS/IT domain is that EA management processes resemble existing IS/IT architecture management processes [8,9]. In advanced cases, in addition to architecture development processes, processes for the communication of architecture models, for the management of architecture skills, and for the enforcement of architectural guidelines and designs are implemented.…”
