Many have suggested using Domain-Driven Design (DDD) to help define the functional scope of microservices. But how to apply this idea in practice is not clear to everyone. DDD is a domain modeling technique created in the early 2000s. Microservices is an architecture style that became popular in 2015 as means to break software solutions into a set of independently deployed services. In this full-day tutorial we’ll cover basic DDD concepts and discuss why and how DDD can help to create microservices with better availability, scalability, reliability, and modifiability. Using examples, we’ll navigate from a domain model created using DDD to the design of both synchronous (REST-based) and asynchronous (reactive) microservices. We’ll explore five different microservice design scenarios around DDD aggregates, bounded contexts (BC), domain events and other strategies for inter-BC interaction.
许多人建议使用领域驱动设计(Domain-Driven Design, DDD)来帮助定义微服务的功能范围。但是,如何在实践中应用这一思想,并不是每个人都清楚。DDD是21世纪初创建的一种领域建模技术。微服务是一种架构风格,在2015年开始流行,它将软件解决方案分解为一组独立部署的服务。在这个全天的教程中,我们将介绍基本的DDD概念,并讨论DDD为什么以及如何帮助创建具有更好可用性、可伸缩性、可靠性和可修改性的微服务。通过示例,我们将从使用DDD创建的域模型导航到同步(基于rest)和异步(响应式)微服务的设计。我们将探讨围绕DDD聚合、边界上下文(BC)、域事件和其他BC间交互策略的五种不同的微服务设计场景。

Internet of Things (IoT) systems are complex and multifaceted, and the design of their architectures needs to consider many aspects at a time. Design decisions concern, for instance, the modeling of software components and their interconnections, as well as where to deploy the components within the available hardware infrastructure in the Edge-Cloud continuum. A relevant and challenging task, in this context, is to identify optimal deployment models due to all the different aspects involved, such as extra-functional requirements of the system, heterogeneity of the hardware resources concerning their processing and storage capabilities, and constraints like legal issues and operational cost limits. To gain insights about the deployment decisions concerning IoT systems in practice, and the factors that influence those decisions, we report about an industrial survey we conducted with 66 IoT architects from 18 countries across the world. Each participant filled in a questionnaire that comprises 15 questions. By analyzing the collected data, we have two main findings: (i) architects rely on the Cloud more than the Edge for deploying the software components of IoT systems, in the majority of the IoT application domains; and (ii) the main factors driving deployment decisions are four: reliability, performance, security, and cost.
物联网(IoT)系统是复杂且多方面的,其架构设计需要同时考虑许多方面。例如,设计决策涉及软件组件及其互连的建模,以及在Edge-Cloud连续体中的可用硬件基础设施中部署组件的位置。在此上下文中,一个相关且具有挑战性的任务是根据所涉及的所有不同方面确定最佳部署模型,例如系统的额外功能需求、涉及其处理和存储能力的硬件资源的异构性,以及法律问题和操作成本限制等约束。为了深入了解物联网系统在实践中的部署决策,以及影响这些决策的因素,我们报告了我们对来自全球18个国家的66位物联网架构师进行的一项工业调查。每位参与者填写了一份包含15个问题的问卷。通过分析收集到的数据,我们有两个主要发现:(i)在大多数物联网应用领域,架构师更依赖于云而不是边缘来部署物联网系统的软件组件;驱动部署决策的主要因素有四个:可靠性、性能、安全性和成本。

The Electronic Health Record (EHR) is a digital document that stores sensitive patient information. In this regard, there are novel techniques and methods for satisfying security in EHR in specific domains (such as authentication, networking, cryptography, among others). Nevertheless, there is not enough evidence on quality instruments composed of cross-cutting security metrics obtained from academic as well as grey literature. This article proposes a quality instrument that measures the satisfaction degree of security in EHRs. The instrument is composed of five security approaches and nineteen security metrics collected and characterized from the academic and grey literature. We evaluated the effectiveness of the quality instrument in a case study with 20 healthcare actors in Chile. The results suggest that the metric is quite effective, but it depends on the degree of security training of the clinical staff. The findings of this study support the idea that our quality instrument can be considered as a starting point to evaluate the quality of EHRs.
电子健康记录(EHR)是存储敏感患者信息的数字文档。在这方面,有一些新的技术和方法可以在特定领域(如身份验证、网络、加密等)满足电子病历的安全性。然而,从学术和灰色文献中获得的由横切安全度量组成的质量工具没有足够的证据。本文提出了一种测量电子病历安全满意度的质量工具。该工具由五种安全方法和十九种安全指标组成,这些指标是从学术和灰色文献中收集和表征的。我们在对智利20个医疗保健机构的案例研究中评估了质量工具的有效性。结果表明,该指标是相当有效的,但它取决于临床工作人员的安全培训程度。本研究的结果支持我们的质量仪器可以作为评估电子病历质量的起点。

Software reuse is a software engineering technique that fosters productivity and quality by encouraging the reuse of existing software artifacts. Despite advantages, we have identified that software engineers must cope with independent and isolated reuse activities. This isolation can hinder the success of an effective reuse activity. In this paper, we discuss how an integrated support for reuse would benefit this activity. Based on a previous approach for developing directed System of Systems (SoS), and on a systematic mapping about integration of reuse environments, we have identified that SoS and Service Oriented Architecture could be employed together for leveraging reuse, and this has motivated us to design and develop a new directed SoS, named SoS-Reuse. As validation, SoS-Reuse has been qualitatively assessed with software architects. Therefore, we claim that our SoS proposal could be used as a stepping stone to improve the reuse activity and for creating similar SoS for other domains.
软件重用是一种软件工程技术,通过鼓励现有软件工件的重用来提高生产力和质量。尽管有优势,我们已经确定软件工程师必须处理独立和隔离的重用活动。这种隔离会阻碍有效重用活动的成功。在本文中,我们将讨论对重用的集成支持如何使该活动受益。基于先前用于开发定向系统的系统(SoS)的方法,以及关于重用环境集成的系统映射,我们已经确定了SoS和面向服务的体系结构可以一起用于利用重用,这促使我们设计和开发新的定向SoS,命名为SoS-重用。作为验证,软件架构师已经对soa -重用进行了定性评估。因此,我们声称我们的SoS建议可以用作改进重用活动和为其他领域创建类似的SoS的垫脚石。

Continuous security patch delivery and risk management for medical devices 医疗设备的持续安全补丁交付和风险管理
Pub Date : 2020-03-01 DOI: 10.1109/ICSA-C50368.2020.00043
H. V. Stockhausen, M. Rose
This paper is a case study describing our practical experience in the area of cybersecurity for medical devices. We describe how Siemens Healthineers uses a continuous security patch delivery model in a regulated market across 15+ business lines which cover our huge portfolio of imaging modalities, laboratory and point-of-care instruments. The case study addresses how we have implemented a continuous security patch delivery strategy. The strategy embraces a systematic way of product-specific vulnerability evaluations based on design knowledge and operator-oriented risk communication which are the novel aspects of this work. Focusing on the ‘real’ cybersecurity risks in the early phase of the continuous delivery process leads to reduced cost for post-market management of medical devices. The paper also describes how this dynamic, continuous and highly automated approach is intended to satisfy the current and future demands of the National Telecommunications and Information Administration (NTIA) the existing FDA post-market guidance and the upcoming revision of the FDA pre-market guidance on cybersecurity to provide operators with a “software bill of material” (SBOM).
本文是一个案例研究,描述了我们在医疗设备网络安全领域的实践经验。我们介绍了西门子健康工程师如何在15多个业务线的监管市场中使用持续的安全补丁交付模式,这些业务线涵盖了我们庞大的成像模式、实验室和护理点仪器产品组合。案例研究讨论了我们如何实现持续的安全补丁交付策略。该策略包含了一种基于设计知识和面向操作人员的风险沟通的系统的特定产品脆弱性评估方法,这是本工作的新颖方面。在持续交付过程的早期阶段关注“真正的”网络安全风险,可以降低医疗器械上市后管理的成本。该文件还描述了这种动态、持续和高度自动化的方法如何满足国家电信和信息管理局(NTIA)现有的FDA上市后指南和即将修订的FDA上市前网络安全指南的当前和未来需求,以向运营商提供“软件材料清单”(SBOM)。

Blockchain technology has been applied in several areas, ranging from financial to health. Although this technology offers benefits, for instance the immutability, anonymity, and decentralization of information, its use presents some problems, been the scalability in terms of storage size one of them. This paper presents a scalable architecture for sharing electronic health records using a multi-channel hyperledger blockchain. The architecture uses one blockchain to record patient visits and one blockchain for each health institution to record links that point to Electronic Health Records (EHRs) stored in external systems. Among the main conclusions, the final results highlight the scalability of the proposed architecture, when compared to the related work models in the heterogeneous network.
区块链技术已应用于从金融到健康等多个领域。尽管这种技术提供了一些好处,例如信息的不变性、匿名性和去中心化,但它的使用也带来了一些问题,其中之一就是存储大小方面的可伸缩性。本文提出了一种可扩展的架构,用于使用多通道超级账本区块链共享电子健康记录。该架构使用一个区块链来记录患者就诊情况,每个医疗机构使用一个区块链来记录指向存储在外部系统中的电子健康记录(EHRs)的链接。在主要结论中,与异构网络中的相关工作模型相比,最后的结果突出了所提出的体系结构的可扩展性。

HLA typing testing has a crucial role in identifying compatibility between organ donors and recipients. These evaluations need to be performed by specialized laboratories that, in general, have modern equipment but do not have an effective management system that controls the entire process. The HLA typing process is complex and extensive, involving diverse teams and sectors of the laboratory, with an intense exchange of information. Data processing is extremely important and requires strict control to ensure the traceability and reliability of results. This paper presents a case study of the development of an information system for managing an HLA typing laboratory. Moreover, A detailed study of the information flow of the HLA typing process is presented, as well as an implementation of a customizable control system for laboratory processes management. It is expected that from the use of this software in the HLA-UERJ laboratory, it can be disseminated in other public laboratories in the state of Rio de Janeiro.
HLA分型测试在确定器官供体和受体之间的相容性方面起着至关重要的作用。这些评价需要由专门的实验室进行,这些实验室一般具有现代化的设备,但没有控制整个过程的有效管理系统。HLA分型过程复杂而广泛,涉及实验室的不同团队和部门,信息交流频繁。数据处理非常重要,需要严格控制,以确保结果的可追溯性和可靠性。本文介绍了HLA分型实验室管理信息系统的开发实例。此外,详细研究了HLA分型过程的信息流,并实现了一个可定制的实验室过程管理控制系统。预期通过在HLA-UERJ实验室使用这一软件,它可以在里约热内卢州的其他公共实验室中传播。

Multi-tenant Quality Attributes to Manage Tenants in SaaS Applications SaaS应用中管理租户的多租户质量属性

A Software-as-a-Service offering provides ready to use solutions for its tenants. Tenants having different quality requirements are deployed on separate dedicated instances. The concerns related to generating variable quality responses using single instance are not explicitly handled in current design approaches. A lack of standardized tactics and design guidelines also make it difficult for an architect to embed these multi-tenant design decisions at the early stage. In this work, we highlight a few domain-independent architectural concerns that can be used to manage multiple heterogeneous tenants on a shared application instance. We derive some quality requirements that are significant in the multi-tenant scenario, related tactics, measurements and analyze the impact on other software product quality attributes.
软件即服务产品为其租户提供即用解决方案。具有不同质量要求的租户部署在单独的专用实例上。在当前的设计方法中,与使用单个实例生成可变质量响应相关的问题没有得到明确的处理。缺乏标准化的策略和设计指南也使得架构师很难在早期阶段嵌入这些多租户设计决策。在这项工作中,我们重点介绍了一些与领域无关的体系结构问题,它们可用于管理共享应用程序实例上的多个异构租户。我们得出了一些在多租户场景中很重要的质量需求、相关的策略、度量和分析对其他软件产品质量属性的影响。

We derive some quality requirements that are significant in the multi-tenant scenario, related tactics, measurements and analyze the impact on other software product quality attributes.","PeriodicalId":202587,"journal":{"name":"2020 IEEE International Conference on Software Architecture Companion (ICSA-C)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123023596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern companies need to revisit and constantly improve their business practices in order to remain profitable in the light of the global competition. Digital Ecosystems (DE) have emerged as an innovative approach to business because they transcend traditional collaborative environments towards an interactive digital environment with the intensive participation of diverse external actors. However, adjusting the existing business processes to the digital environment is not simple, especially taking into account the culture of the DE actors and the characteristics of such environment. The same issue applies when the ecosystem is focused on software development as investigated in a Software Ecosystem (SECO). In this context, this study aims to understand how the management of traditional business processes can be applied into DE or SECO management. To this end, a systematic mapping study regarding business process management in DE and SECO is presented. This study is important since it helps researchers and practitioners to understand how these processes can provide inputs for modeling relationships among the DE actors, besides providing support to ecosystem managers. The study confirms that the use of business process management techniques or methods as a support for DE or SECO managers or developers is an emergent field.
现代企业需要重新审视并不断改进其商业实践,以便在全球竞争中保持盈利。数字生态系统(DE)已经成为一种创新的商业方法,因为它们超越了传统的协作环境,转向了具有多种外部参与者密集参与的交互式数字环境。然而,将现有业务流程调整到数字环境并不简单,特别是要考虑到DE参与者的文化和这种环境的特征。同样的问题也适用于在软件生态系统(SECO)中研究的专注于软件开发的生态系统。在此背景下,本研究旨在了解传统业务流程的管理如何应用于DE或SECO管理。为此,本文对DE和SECO的业务流程管理进行了系统的映射研究。这项研究很重要,因为它有助于研究人员和实践者了解这些过程如何为DE参与者之间的关系建模提供输入,以及为生态系统管理者提供支持。该研究证实,使用业务流程管理技术或方法作为DE或SECO管理人员或开发人员的支持是一个新兴领域。
