A Quality Model for Evaluation and Selection of Software Services in Cloud

This paper presents the issues on the formation of the innovation policy of a road transport enterprise. The innovation policy is a key factor in the construction of a general strategy of the enterprise, i.e. the basic foundation for the subsequent development of the process and network strategy, marketing and financial policy. Considerable attention is paid to the identification and ranking of the key problems faced by the Russian road transport enterprises in modern conditions. The paper presents a comprehensive assessment of the innovative capacity of the road transport enterprise by grade method, integral method and in graph form. The measures to improve the organizational support of the innovation activities are determined. The cloud computing has technologically advanced as a unique paradigm where all resources are provided as a service through network based systems in many organizations and application domains. The major and crucial benefit of cloud computing is effective use of resources and business dynamism expected at an organization. The cloud-computing environment is an integration of necessary infrastructure including network resources, internet, appropriate hardware and software technologies used for availing different resources as services. The major three important service models are 1) Infrastructure as a Service (IaaS), 2) Platform as a Service (PaaS), and 3) Software as a Service (SaaS). Among all three services, the enhancement of the present research is on the SaaS, as it is most widely used and reused for providing the best possible benefits to cloud service users with practically no cost. The resources within the cloud computing are used on- demand, extended indeterminately and attained services at any time by the service users. The term ‘pay-per-use’ is more attracting the services users to use several services available in the cloud. When it comes to use the software as a service, there are different issues such as how to select the best software service product, how to evaluate the software product, which tools will be appropriate for evaluation, how to deploy the software service product etc. To address these issues in the present research the primary objective is to provide simple mechanism to select the possible software service from the group of software services, to investigate and describe main quality attributes of software as well as service and to look at the main metrics for each measurable attribute of a Software Service. To achieve these objectives the proposed research work is carried out in two aspects as follows: first one is for evaluating software service quality from the service provider’s perspective i.e. Software as a Service (SaaS) in the Cloud Quality, named as SaaS Cloud Qual and the second one is for selecting software service from the group of services in the cloud from the service user’s perspective i.e. Software as a Service (SaaS) in the Cloud Clustering Approach(grouping of software services) named as SaaS Cloud Cluster
