Arquitetura de microsserviços: quando vale a pena migrar?

Abstract

The continuous growth of complexity in current systems caused, among others, by the exponential reach of the internet, has led the software industry and the academic community to investigate new ways of solving problems that meet the need for systems to operate in a larger context, given the explosion of information and the greater need for integration between systems and services. Traditionally, companies build their systems in a monolithic way and if they later understand that there is a need to "divide" the application, it is used incrementally to separate it, so creating microservices (J. THÖNES, 2015). Microservices is a style and standard of software architecture in which complex systems are broken down into smaller services that work together to form larger services. Microservices are autonomous, independent and independently implantable services. This work aims to assist the architect and / or software developer through a proposal to apply a questionnaire that wants to facilitate decision making regarding the architectural migration of a software project. A bibliographic study was made, where several factors were analyzed and identified in a project, with this, they suggest that an architectural migration to microservices tgat can bring substantial benefits to the project. In this context, architects and / or developers can use the questionnaire proposed by this work as an auxiliary tool in the decision support process for the organization, through a theoretical basis on the main characteristics that motivate architectural migration, such as maintainability, scalability and use different technologies, along with examples mentionaded in the literature that say when to migrate or not.
