Query: Does Migrate a Monolithic System to Microservices Decrease the Technical
  Debt?   Background. The migration from monolithic systems to microservices involves
deep refactoring of the systems. Therefore, the migration usually has a big
economic impact and companies tend to postpone several activities during this
process, mainly to speed-up the migration itself, but also because of the need
to release new features. Objective. We monitored the Technical Debt of a small
and medium enterprise while migrating a legacy monolithic system to an
ecosystem of microservices to analyze changes in the code technical debt before
and after the migration to microservices. Method. We conducted a case study
analyzing more than four years of the history of a big project (280K Lines of
Code) where two teams extracted five business processes from the monolithic
system as microservices, by first analyzing the Technical Debt with SonarQube
and then performing a qualitative study with the developers to understand the
perceived quality of the system and the motivation for eventually postponed
activities. Result. The development of microservices helps to reduce the
Technical Debt in the long run. Despite an initial spike in the Technical Debt,
due to the development of the new microservice, after a relatively short
period, the Technical Debt tends to grow slower than in the monolithic system.
