ABSTRACT:
The Software as a Service (SaaS) of the Cloud Computing is the type of software that today is an important means for the development task in business processes, giving positives impacts on customers as well competitive business advantages for providers and developers of services.
For the production or personalization of SaaS effectively, it is important that the providers correctly control the quality of services, such as reuse, composition, adaptability and elasticity of atomic services or microservices as well composite software services.
One of the problems presented in the SaaS is that it does not comply in time and form or does not reach to produce the results desired by the customer in execution time. One of the main causes is the degree of availability that have the atomic services, witch are part of their workflow, to execute correctly.
This paper presents a dynamic orchestration method of services which aims is to verify, in time execution, the actual availability of the atomic services of the workflow that make up the SaaS, and that allows reconstructing it with those atomic services that comply with the availability necessary to achieve the consumer´s requirements in a timely manner. To achieve this, the method identifies atomic services that may present problems due to their degree of availability and replace them with replicas or other candidate atomic services that meet the requirements of the original service, altering the workflow of SaaS to support its successful execution.
The method was implement in Java language and tested in a simulated cloud environment by means WorkflowSim tool resulting in SaaS workflows complying in a timely manner with the consumer´s requirements.
