Load Balancing Algorithm

A practical, flexible, versatile, and heterogeneous distributed computing framework is presented that simplifies the creation of small-scale local distributed computing networks for the execution of computationally expensive black-box analyses. The framework is called the Dynamic Service-oriented Optimization Computing Framework (DSOCF), and is designed to parallelize black-box computation to speed up optimization runs. It is developed in Java and leverages the Apache River project, which is a dynamic Service-Oriented Architecture (SOA). A roulette-based real-time load balancing algorithm is implemented that supports multiple users and balances against task priorities, which is superior to the rigid pre-set wall clock limits commonly seen in grid computing. The framework accounts for constraints on resources and incorporates a credit-based system to ensure fair usage and access to computing resources. Experimental testing results are shown to demonstrate the effectiveness of the framework.

Security Standards

Web services and Service oriented architecture are innovative phase of distributed computing, build on top of the distributed computing models. Web services are being used mostly for the integration business components. One of the key concerns in web services and service oriented architecture is implementation of adequate security. Security issues in SOA are still probing and in spite of an increase in web service research and development, many security challenges remain unanswered. This chapter introduces the vulnerabilities, threats associated with web services and addresses WS-Security standards and countermeasures. Web service protocol is designed to provide connectivity. Not any of these standards of web services contain any inbuilt security aspect of their own. Web Services are exposed to attack from common Internet protocols and in addition to new categories of attacks targeting Web Services in particular. Consequently, the aim of this chapter is to provide review of security mechanism in web services.

Aircraft Accident

The performance of airplane in commercial airline environment is determined by, and therefore an indicator of performance measure of, the thermodynamic properties of airplane. The aim of this study was to establish the use of simulators to determine aircraft accident for a flight of airplanes and evaluate the potential of new airspace structure and airport’s runway. This indicates that there is a possibility of obtaining airplane performance from analysis and verification simulating airplane. As compared with AIRBUS Full Flight Simulator, a multiple aircrafts flight simulator that grouping aircrafts simultaneously take off and land was presented, which is basis on a parallel distributed computing in Open Grid Computing Environment (OGCE), and service oriented architecture (SOA) of software in multiple aircraft simulator, the performance of collaborative flight of multiple aircrafts is evaluated.

Heterogeneous Resources

A geospatial portal is a repository of distributed geospatial data, tools and services, and supports the publishing, management, search, use and sharing of the resources. Geospatial portals have been developed as clearinghouses, metadata portals, data warehousing, and recently geospatial portals incorporated the Service Oriented Architecture and distributed computing to make service-oriented portals. In addition to software and computational challenges, ontology and semantics play an increasingly important role in geospatial portals due to the demand of interoperability. The interoperation and communication of data, tools and services become critical when heterogeneous resources are consolidated and exchanged on geospatial portals. This chapter provides an updated overview of geospatial portals followed by detailed discussion on how the ontological and semantic technologies are incorporated into geospatial portals. Three recent research and practice of geospatial portals are briefly introduced as the case studies of service-oriented portals.

Microservice Architecture

A new programming paradigm is considered, not related to objects, but to business processes and their components — business functions, when the layout of applications is carried out by identifying and calling services (special software components with unified interfaces), available on the network to perform the necessary task. This approach is independent of specific programming languages ​​and operating systems, and involves the use of a service-oriented architecture (SOA) of applications built on formalized business processes whose functions are presented as reusable services with transparently described interfaces. The fundamentals of the educational program for the training of specialists are considered who are able to meet the need for effective implementation of new paradigms of distributed computing (on the example of cloud computing, microservice architecture, semantic technologies); for creating an online toolkit that allows end users to dynamically compile application workflows according to their scripts in different subject areas; for filling and merging repositories of web services that can run on different cloud sites in distributed computing environments.

Service-oriented architecture (SOA)[1] is an incessant term to deal with various administrations dependent on solicitations of various clients in various ongoing applications. Still, now, a few people don't have total information about what SOA really has done, they get confounded how SOA identifies with distributed computing. On account of cloud administration usage in SOA need security mindful help creation with finegrained stream control to make sure about web administrations at execution time to share various administrations to various clients in dispersed condition? Routinely various models were acquainted with investigating secure web administrations at execution of various administrations. Because of access control infringement, they will take high execution time and other leader boundaries profoundly, and furthermore they don't control access assurance arrangements in composite administrations, which may deliver bothersome information spillage. To conquer these infringement issues in SOA, we present Integrated Novel Multi-Level Composite Service Model (INMLCSM)[2] to lessen infringement calculation cost dependent on customer authentic and demonstrate customer composite administrations and furthermore perform nearby/distant strategy calculation for highest customers. We acquaint idea of change factor with characterize halfway administrations. Our proposed approach portrays forceful exploratory outcomes.
