Technical Experiences on a Microservices-oriented Transformation using Open Source Software

Adopting emerging computing paradigms such as cloud applications include challenges associated to transform legacy software to essential characteristics of the mentioned computing model, e.g. on-demand self-service, broad network access, resource pooling, rapid elasticity and measured services. This paper presents a summary of technical experiences on applying one of the most popular approaches to address transformation of legacy software to cloud-native applications: a microservice-oriented architecture with connections to legacy systems through anti-corruption layers. Several technical considerations are presented, focusing on Open Source Software to include particular features on modern development practices as well as solving issues related to the cloud-native transformation.
