Derivation of Process-Oriented Logical Architectures: An Elicitation Approach for Cloud Design

Using the NIST Reference Model for Refining Logical Architectures

“…A logical architecture can be considered a view of a system composed of a set of problem-specific abstractions supporting functional requirements [11,12]. The logical architecture acts as a common abstraction of the system, providing a representation to facilitate its comprehension by all stakeholders regardless their background.…”

“…The logical architecture acts as a common abstraction of the system, providing a representation to facilitate its comprehension by all stakeholders regardless their background. The requirements for process-level can be also represented in a logical architecture [11]. The process-level architecture represents the fundamental organization of service development, service creation, and service distribution in the relevant enterprise context.…”

“…Process architecture is an arrangement of the activities and their interfaces in the process. It takes into account some non-functional requirements, such as performance and availability, and it can be represented with components, connectors, systems, components and connectors, ports, roles, representations and rep-maps, as well as Architectural Elements (AEs) [11].…”

“…Other researches use NIST CCRA to analyse, improve, and design Cloud architectures. Few works [11,12,13] apply this model to define cloud-based infrastructures and services.…”

“…This approach enables us to analyse which logical architecture AEs comply with the reference model, to discover requirements for supporting Cloud, and to design Cloud architectures to support Cloud-based solutions and services for specific contexts. Our approach uses the NIST CCRA as reference model [11]. The use of the NIST CCRA enables the identification and correction of semantic incoherencies, and the identification and definition of Cloud requirements.…”
