Migrating from monolithic architecture to microservices: A Rapid Review Microservices architecture has become enormously popular because traditional monolithic architectures no longer meet the needs of scalability and rapid development cycle, and the success of some large companies in building and deploying services is a strong motivation for others to consider making the change. However, performing the migration process is not trivial. Most systems acquire too many dependencies between their modules, and thus canu0027t be sensibly broken apart. It is for this reason that studies that provide information associated with the migration process to practitioners are necessary. This study gathers, organizes and analyzes 20 migration techniques proposed in the literature. Results show that most proposals use approaches based on design elements as input; 90% of the proposals were applied to objectoriented software (Java being the predominant programming language); And that the main challenge is to perform the database migration.

MicroValid: A Validation Framework for Automatically Decomposed Microservices In a dynamic world of software development, the architectural styles are continuously evolving, adapting to new technologies and trends. Microservice architecture (MSA) is gaining adoption among industry practitioners due to its advantages compared to the monolithic architecture. Although MSA builds on the core concepts of Service Oriented Architecture (SOA), it pushes for a finer granularity, with stricter boundaries. Due to cost rationale, numerous companies choose to migrate from the monolithic style instead of developing from scratch. Recently, semiautomatic decomposition tools assist the migration process, yet a crucial part is still missing: validation. The current study focuses on providing a validation framework for microservices decomposed from monolithic applications and complete the puzzle of architectural migrations. From previous work we select quality attributes of microservices that may be assessed using static analysis. We then provide an implementation specification of the validation framework. We use five applications to evaluate our approach, and the results show that our solution is scalable while providing insightful measurements of the assessed quality attributes of microservices.
