Embedded systems are supporting the trend of moving away from centralised, high-cost products towards low-cost and high-volume products; yet, the non-functional constraints and the device heterogeneity can lead to system complexity. In this regard, Service-Oriented Architecture (SOA) is the best methodology for developing a loosely coupled, dynamic, flexible, distributed, and cost-effective application. SOA relies heavily on services, and the Semantic Web, as the advanced form of the Web, handles the application complexity and heterogeneity with the help of ontology. With an ever-increasing number of similar Web services in UDDI, a functional description of Web services is not sufficient for the discovery process. It is also difficult to rank the similar services based on their functionality. Therefore, the Quality of Service (QoS) description of Web services plays an important role in ranking services within many similar functional services. Context-awareness has been widely studied in embedded and real-time systems and can also play an important role in service ranking as an additional set of criteria. In addition, it can enhance human-computer interaction with the help of ontologies in distributed and heterogeneous environments. In order to address the issues involved in ranking similar services based on the QoS and context-awareness, the authors propose a service discovery framework for distributed embedded real-time systems in this chapter. The proposed framework considers user priorities, QoS, and the context-awareness to enable the user to select the best service among many functional similar services.

Web Services for Remote Portlets (WSRP) provide solutions for implementation of lightweight Service Oriented Architecture (SOA). UDDI extension for WSRP enables the discovery and access to user facing web services provided by business partners while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by web service providers from their own servers. Remote portlet consumers are not required to make any changes in their portals to accommodate updated remote portlets. This approach results in easier team development, upgrades, administration, low cost development and usage of shared resources. Furthermore, with the growing interest in SOA, WSRP should cooperate with service bus (ESB).In this paper, the author examines the technical underpinning of the UDDI extensions for WSRP (user facing remote web services) and their role in service sharing among business partners. The author also briefly outlines the architectural view of using WSRP in enterprise integration tasks and the role Enterprise Service Bus (ESB).

In most cases, portlets are built to be deployed by local portals. This is not practical if the organisation wishes to publish their Web services and expects other business partners to use these services in their portals. UDDI extension for WSRP enables the discovery and access to user facing Web services provided by business partners while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by the Web service providers from their own servers. Remote portlet consumers are not required to make any changes in their portals to accommodate updated remote portlets. This results in easier team development, upgrades, administration, low cost development, and usage of shared resources. In this chapter, we deal with the technical underpinning of the UDDI extensions for WSRP (user facing remote Web services) and their role in service sharing among business partners. We outline the WSDL extensions relevant to the remote portlets and WSRP (WSRP specification version 1, 2003). publishing and binding process in UDDI.

Spark Framework

Urban has developed an elastic and powerful approach to the analysis of massive datasets using Amazon Web Services’ Elastic MapReduce (EMR) and the Spark framework for distributed memory and processing. The goal of the project is to deliver powerful and elastic Spark clusters to researchers and data analysts with as little setup time and effort possible, and at low cost. To do that, at the Urban Institute, we use two critical components: (1) an Amazon Web Services (AWS) CloudFormation script to launch AWS Elastic MapReduce (EMR) clusters (2) a bootstrap script that runs on the Master node of the new cluster to install statistical programs and development environments (RStudio and Jupyter Notebooks). The Urban Institute’s Spark for Social Science Github page holds code used to setup the cluster and tutorials for learning how to program in R and Python.

The goal of distributed heterogeneous information integration is seamless interactions among different business tasks. To achieve the goal, the paper presents a novel middleware framework in service oriented computing (SOC) environment. We analyze the framework in detail and propose three steps for integrating the heterogeneous information resource, including heterogeneous databases. The unified user interface is provided which invoking and binding Web services more dynamically and flexibly in the framework. Especially, we put forward the specific realization process of the core modules of the framework. As an example, we propose the realization of wrapping heterogeneous database as Web services. Finally, we propose the services oriented business integration process and provide the remedial measures for the model of the business process integration. The approach can achieve low cost, flexibility to change and full of system extensibility for distributed heterogeneous information integration.
