Three profiles are used to document SOA architecture. The ‘Service oriented
architecture Modeling Language’ (SoaML) [16] is a standard used to design a SOA
solution that is independent from its implementation. The ‘Modeling and Analysis
of Real-Time and Embedded Systems’ (MARTE) [17] profile supports model-based
description of real time and embedded systems. It provides a set of annotations with
are required to perform performance analysis. BPEL profile [20] is concerned with
modeling an individual process components which will be deployed as automated
processes.
C. NATO Architecture Framework
The NATO Architecture Framework (NAF) [12] supports structured approach
to documenting architectures and manage their complexity. It provides the rules,
guidance, and product descriptions for developing, presenting and communicating
architectures. It facilitates understanding, comparing and integrating the architectures
developed by NATO and Nations.
NAF defines ‘views’ and ‘subviews’ that can be used to communicate the architecture
information to a variety of a stakeholders. A view is defined as a set
of subviews grouped by purpose. A subview is defined as a pattern from which
to develop an individual products. Each product has a defined purpose, audience
and the techniques for its creation and analysis. The system model documented
in NAF subviews is a base for performance model generation. The subviews selected
to document a SOA system architecture are depicted on Fig. 3. Additionally,
mentioned subviews are required for system performance evaluation.
