Towards Services-Based Enterprise Architecture for Cloud Computing-Opened Information Systems

Abstract

With the development of cloud computing technologies and the multiplication of enterprise architecture reference frameworks, the industrials are encouraged to take into account the new concepts of cloud service in the evolution of their information system strategies. The present paper starts by presenting background concepts and the state of the art of the enterprise architecture, in order to propose a maturity model that helps enterprises to build and evaluate a functional component of their Information System architecture and allow them to qualify its externalization to the Cloud Computing as well as its monitoring.

Examination of explicit definitions of enterprise architecture

“…“ The EA is a base of strategic information asset, which defines the mission , the information needed to carry out the mission , the technology required to perform the mission , and the transition process of the implementation of new technologies in response to the evolving of the mission. ” 61…”

Pemodelan Sistem Informasi Order Fullfillment Pada Perusahaan Diesel Menggunakan Enterprise Architecture Planning Archimate

“…Dalam hal ini, perusahaan terdiri dari beberapa divisi yang harus dikelola oleh aturan yang jelas, dan tentu saja akan membutuhkan sistem informasi yang terintegrasi. Untuk mengembangkannya, perusahaan dapat menggunakan pendekatan perencanaan arsitektur [16]. Salah satu dasar perencanaan enterprise architechture adalah mengatasi integrasi di seluruh perusahaan, melalui prinsip metode yang digunakan untuk memetakan struktur organisasi, proses bisnis, aliran informasi, sistem informasi dan infrastruktur [17][18].…”

Maturity Model for Cloud Computing Transformation Assessing an Information System s Functional Block Maturity

“…Information Systems Urbanism (ISU) or Enterprise Architecture (EA) is a concept inspired from town planning and used in Information Systems [4]. It refers to the IS architecture which allow a company to develop an evolution plan of it's IS in short, medium and long term.…”

“…Figure 3 provides an overview on the position of the proposed model. This model is a maturity assessment and decision support tool for the opening of enterprise IS on cloud computing [4].…”

“…These tools are based on the assessment of the functional component maturity. This model will also be useful to anticipate the construction of IS evolution plan by studying the possible improvement scenarios especially the outsourcing to the cloud computing [4]. This paper presents a decision support model based on the maturity of an informational component (functional block of an IS architecture).…”
