Background: Cloud Computing has drawn much attention in the industry due to its costefficient schema along with more prospects, such as elasticity and scalability nature of Cloud Computing. One of the main service models of a Cloud is software as a service, where many web services are published and hosted in the Cloud environment. Many web services offered in a Cloud have similar functionality, with different of characteristics non-functional requirements such as Quality of Service (QoS). In addition, as individual web services are limited in their capability. Therefore, there is a need for composing existing services to create new functionality in the form of composite service to fulfill the requirements of Cloud user for certain processes. Methods: This paper introduces a fuzzy rule approach to compose web service based on QoS from different Cloud Computing providers. The fuzzy rule is generated based on QoS of discovered web service from Cloud in order to compose web services that only match user requirements. The proposed model is based on an agent that is responsible for discovering and composing web service that only stratified user requirements. Results: the experimental result shows that the proposed model is efficient in terms of time and the use of fuzzy rules to compose web services from different Cloud providers under different specifications and configurations of Cloud Computing environment. Conclusion: In this paper, an agent-based model was proposed to compose web services based on fuzzy rule in Cloud environment. The agent is responsible for discovering web services and generating composition plans based on offered QoS for each web service. The agent employs a set of fuzzy rules to carry out an intelligent selection to select the best composition plan that fulfills the requirements of the end user. The model was implemented on CloudSim to ensure the validity of the proposed model and performance time analysis was performed that showed good result in terms of time with regard to the Cloud Computing configuration.

Recovery Approach

A key challenge in B2B and B2C applications involving dynamic composition of workflow activities is to ensure their reliable execution, in view of frequent failures in the internet environment where a composed service is executed. Existing approaches for transactional coordination of composite web services, consider forward and backward recovery alone, in order to maintain consistency in the case of failures. However, while achieving reliable execution, service cancellability is important due to the predominance of long running processes in business applications and frequently changing user requirements and business policies. If the execution of a long running process is not cancelled in the case of a changed requirement, the completion of the process results in wastage of resources and the outcome may no longer be useful. Hence, a transactional coordination framework named as Tx-FAITH is proposed to handle the cancellation recovery under the external interruption and cancellation of transactions. Tx-FAITH considers hierarchically composed web services whose components are recursively nested to form a composition and adapts a coordination approach based on context information. The proposed coordination and recovery approach when tested with 200 simultaneous users and with a database size of 0.35 million records, incurs only 10 seconds to process a request.

As the number of Mobile Web Services (MWS) with different specifications has increased, the task of discovering the relevant ones becomes more challenging in a mobile environment. The challenges include mobile devices constraints and web service descriptions itself. The issues can be considered from the aspect of mobile device’s performance, diversity of available MWS specifications and lack of enriched MWS descriptions. In order to address these issues, this paper presents an enhancement of semantic-based MWS discovery framework for discovering the most relevant MWS that takes into consideration of Non-Functional Properties (NFPs) in web service descriptions. In our work, the matchmaking algorithm with enhanced similarity measure is presented. Semantic MWS profiles are annotated semantically as a WSMO-Lite profile with a REST-based architecture. The experimental validation and statistical analysis demonstrates that the proposed framework can effectively discover relevant MWS according to the various user requirements. It can be concluded that using the proposed framework, there is a significant improvement in the effectiveness of semantic-based discovery for MWS in mobile computing environments.

Over the last few years, e-commerce has exhibited explosive growth due to the ease of availability of the internet. E-commerce is rapidly changing the way in which businesses are interacting with each other as well as with their consumers. In each innovative e-commerce application, web services are being included as an important component. This leads to the availability of a huge number of web services that provide similar functionalities. The main challenge is to select the appropriate web service which fulfills the end user requirements. So, there is a need for a web service selection method that selects the web services not only based on their functionality, but also considers the nonfunctional requirements. This article proposes a method to preprocess web services using the J48 classification technique. After that, a hybrid weight evaluation mechanism is employed to obtain the weight values of each nonfunctional parameter. In the end, the web services that are near to user expectations are selected out using the ranking method.

Food sensory analysis is the terms from the field of Food Technology that has a meaning which means sensory evaluation of food that is conducted by the food sensory evaluators. Currently, food sensory analysis is conductedmanually. It can caus e human errors and consume much ti me. The objective of this research is to build a web based application that is specific for food sensory analysis using PHP programming language. This research followsfour first steps of waterfall software engineering mod el which are user requirements ana lysis (user software and requirements analysis), system design (activity, use cases, architecture, and entity relationship diagram),implementation (software development), and testing (software unit, functionality, validit y, and user acceptance testing). T he software result is well built. It is also acceptable for users and all functionality features can run well after going through those four software testing. The existence of the software brings easiness to deal with the manual food sensory analysis exper iment. It is considered also for the future it has business value by having open source and premium features.

SKK Migas plans to apply end-to-end security based on Web Services Security (WS-Security) for Sistem Operasi Terpadu (SOT). However, there are no prototype or simulation results that can support the plan that has already been communicated to many parties. This paper proposes an experiment that performs PRODML data transfer using WS-Security by altering the WSDL to include encryption and digital signature. The experiment utilizes SoapUI, and successfully loaded PRODML WSDL that had been altered with WSP-Policy based on X.509 to transfer a SOAP message.
