Abstract-Nowadays the access to a cloud computing environment is provided on-demand offering transparent services to customers. Although the cloud allows an abstraction of the behavior of the service providers in the infrastructure (involving logical and physical resources), it remains a challenge to fully comply with the Service Level Agreements (SLAs), because, depending on the service demand and system configuration, the providers may not be able to meet the requirements of the customers. There is a need for mechanisms that take account of load balancing algorithms to provide an efficient load distribution with the available resources. However, the studies in the literature do not effectively address the problem of the availability of resources to meet customers' requirements with analysis restricted to a limited set of objectives. This paper proposes algorithms to address the need for optimization when handling computational resources during the execution time. The methods optimize the efficient use of the resources available in the infrastructure aiming to comply with the service level agreements defined between client and provider.

“…In [4] it is mentioned that, rather than starting with a complete business process definition, the composition system could start with a basic set of requirements and in the first step build the whole process, whereas many approaches (i.e. [6]) require a well-defined business process to compose a complex service.…”

Abstract. In this paper a holistic approach to automated service composition in Service Oriented Architecture is presented. The model described allows to specify both functional and non-functional requirements for the complex service. In order to do so a decomposition of the complex service composition process into three stages is proposed, in which a structure, a scenario and an execution plan of a complex service is built. It is believed that service composition tool based on the proposed model will be able to create complex services satisfying efficiently both functional and nonfunctional requirements.

SUMMARYService-based approach has been successfully applied to distributed environments, modelling them as pieces of functionality that exchange information by means of messages in order to achieve a common goal. The advantages of this approach can be also be applied to distributed real-time systems, increasing their flexibility and allowing the creation of new brand applications from existing services in the system. If this is an online process, then time-bounded composition algorithms are needed to not jeopardize the performance of the whole system. Different composition algorithms are studied and proposed, two of them optimal and another two based on heuristics. This paper presents an analytical solution that selects, depending on the structure of the application and on the load of the whole system, the most suitable composition algorithm to be executed in order to obtain a composed application in bounded time.
