Some Aspects of Reliability Estimation of Loosely Coupled Web Services in Clustered Load Balancing Web Server

Background

WS is the platform where one can deploy software modules as service agents. It supports configuration of loosely or tightly coupled software modules for business process. It provides a programmable interface where the integration of different functional logic can be executed (Matthew et al., 2005). The internal configuration files and data structure of WS is omitted from outside world. As such, the consumer simply utilizes the basic operation of WS. The overall service computing that comprises of service delivery, execution and publishing is defined as Service Oriented Computing (SOC). However, based on computational logic, the deployment of SOC primarily follows loosely or tightly coupled WSs. The publicity of WSs is primarily executed through Web Service Description Language (WSDL), that generates necessary executable files in server side for successful establishment of communication among platforms (WSDL, 2016). The XML is used to communicate external remote service. This is carried out along with the Simple Object Access Protocol (SOAP) features (SOAP, 2016). The Universal Description Discovery and Integration (UDDI) is a showcase of service parameters for end users (Peiris et al., 2007). The WSs can communicate in different ways and is discussed elsewhere (Bora et al., 2016).
