Monolithic to Microservices Migration Strategy in Public Safety Secretariat of Mato Grosso

摘要

This paper presents the migration strategy that is being used by Public Safety Secretariat of Mato Grosso (SESP-MT) to convert its legacy systems that are monoliths to a microservice oriented architecture. Despite the standards already defined for a microservice project, it is difficult to find successful processes and practical experiences reports in gradual migration from a monolith to a microservice architecture, especially regard to the legacy database split and separation. Our research group obtained successful results applying the database sharing strategies and migration process described in this paper through a period of monolith and microservice coexistence. This is the contribution of this paper.
