    Towards SLA-Driven API Gateways
    Gámez-Díaz, Antonio; Fernández, Pablo; Ruiz-Cortés, Antonio. Actas de las XI Jornadas de Ciencia e Ingeniería de Servicios (JCIS 2015), 2015-09-15.
    As APIs are becoming popular to build Service-Based Applications (SBA), API Gateways are being increasingly used to facilitate API features management. They offer API management functionalities such as pricing plans support, user authentication, API versioning or response caching. Some parts of the information that an API Gateway needs are already included into a Service Level Agreement (SLA), that providers use to describe the rights and the obligations of involved parties in the service. Unfortunately, current API Gateways do not use any SLA representation model nor SLA underlying technology, thereby missing potential opportunities. In this paper we analyze the state of the art to justify the current situation and we identify some research challenges so as to achieve SLA-Driven API Gateways.

    Towards SLA modeling for RESTful APIs
    Gámez-Díaz, Antonio; Fernández, Pablo; Ruiz-Cortés, Antonio. Actas de las XIII Jornadas de Ciencia e Ingeniería de Servicios (JCIS 2017), 2017-07-19.
    The term of API Economy is becoming increasingly used to describe the change of vision in how APIs can add value to the organizations. Furthermore, a greater automation of RESTful APIs management can suppose a competitive advantage for the company. New proposals are emerging in order to automatize some API governance tasks and increase the ease of use (e.g. generation of code and documentation). Despite that, the non-functional aspects are often addressed in a highly specific manner or even there not exists any solution for an automatic governance. Nevertheless, these properties are already defined in natural language at the Service Level Agreement (SLA) that both customer and provided have established. In this paper, we carry out a study on the *aaS industry and analyze the current both API modeling and SLA modeling proposals in order to identify the open challenges for an automatic RESTful API governance.

    Fostering SLA-Driven API Specifications
    Gámez-Díaz, Antonio; Fernández, Pablo; Ruiz-Cortés, Antonio. Actas de las XIV Jornadas de Ciencia e Ingeniería de Servicios (JCIS 2018), 2018-09-17.
    Software architecture tendencies are shifting to a microser- vice paradigm. In this context, RESTful APIs are being established the standard of integration. API designer often identifies two key issues to be competitive in such growing market. On the one hand, the generation of accurate documentation of the behavior and capabilities of the API to promote its usage; on the other hand, the design of a pricing plan that fits into the potential API user’s needs. Besides the increasing number of API modeling alternatives is emerging, there is a lack of proposals on the definition of flexible pricing plans usually contained in the Service Level Agreements (SLAs). In this paper we propose two different modeling techniques for the de- scription of SLA in a RESTful API context: iAgree and SLA4OAI.
