Chapter 5 – The Architecture View

Abstract

This chapter examines distributed systems from the architectural viewpoint and the way in which architectural aspects affect the behavior of the resulting systems and applications. The main focus is on the structure and architecture of distributed applications, including the functional split of business logic across components, the connectivity between the components, and the storage of application state.

Content includes layered and hierarchical design, architectural models for distributed applications, coupling between components, stateful versus stateless design, middleware, virtual machines, software libraries, replication of services, and system models of collective resources and computation resource provision.

Well-known software architecture models that are discussed include client-server, peer-to-peer, three-tier, multitier, and distributed objects.

Key Words

• Architecture, Complexity in distributed systems, Layered architectures, Heterogeneity,Component coupling, Two-tier applications, Three-tier applications, Client-server,
• Peer-to-peer,
• Distributed objects, Middleware,
• Collective computing resources,Software libraries, Refactoring,Static and dynamic linking, Virtual machines, Static and dynamic configuration, Nonfunctional requirements, Service replication,Transparency.

A novel consumer-centric card management architecture and potential security issues

Abstract

Multi-application smart card technology has gained momentum due to the Near Field Communication (NFC) and smart phone revolution. Enabling multiple applications from different application providers on a single smart card is not a new concept. Multi-application smart cards have been around since the late 1990s; however, uptake was severely limited. NFC has recently reinvigorated the multi-application initiative and this time around a number of innovative deployment models are proposed. Such models include Trusted Service Manager (TSM), User Centric Smart Card Ownership Model (UCOM) and GlobalPlatform Consumer-Centric Model (GP-CCM). In this paper, we discuss two of the most widely accepted and deployed smart card management architectures in the smart card industry: GlobalPlatform and Multos. We explain how these architectures do not fully comply with the UCOM and GP-CCM. We then describe our novel flexible consumer-centric card management architecture designed specifically for the UCOM and GP-CCM frameworks, along with ways of integrating the TSM model into the proposed card management architecture. Finally, we discuss four new security issues inherent to any architecture in this context along with the countermeasures for our proposed architecture.

A systematic mapping study on the combination of software architecture and agile development

Abstract

Context

Combining software architecture and agile development has received significant attention in recent years. However, there exists no comprehensive overview of the state of research on the architecture-agility combination.

Objective

This work aims to analyze the combination of architecture and agile methods for the purpose of exploration and analysis with respect to architecting activities and approaches, agile methods and practices, costs, benefits, challenges, factors, tools, and lessons learned concerning the combination.

Method

A systematic mapping study (SMS) was conducted, covering the literature on the architecture-agility combination published between February 2001 and January 2014.

Results

Fifty-four studies were finally included in this SMS. Some of the highlights: (1) a significant difference exists in the proportion of various architecting activities, agile methods, and agile practices employed in the combination. (2) none of the architecting approaches has been widely used in the combination. (3) there is a lack of description and analysis regarding the costs and failure stories of the combination. (4) twenty challenges, twenty-nine factors, and twenty-five lessons learned were identified.

Conclusions

The results of this SMS help the software engineering community to reflect on the past thirteen years of research and practice on the architecture-agility combination with a number of implications.

Keywords

• Software architecture, Agile development, Architecting approach
