Work Background

MobitraxxSystem Architect Team Lead

Jun. 2023Florianópolis, Santa Catarina, Brazil · Remote(PART-TIME) The process of reimagining a monolithic system into a serverless microservices architecture is a complex undertaking that requires careful planning and execution. In this regard, we present a three-phase approach that we have implemented successfully in our organization. In the first phase, we migrated legacy monolithic systems, including Tomcat Apps, and Databases from Kinghost to AWS Elastic Beanstalk. To prevent downtime, we implemented observability and auto-recovering load balancers. The migration of the 200GB production DB was achieved through AWS DMS service, from a Mysql 8 to AWS Maria DB. We improved our processes by implementing GITHUB pipelines for versioning and deployment and setting up a QA environment for thorough end-to-end tests and homologation. These changes helped us achieve greater efficiency and success in our work." In the second phase, we adopted an event-driven architecture and developed microservices. These microservices were deployed into a low-cost GCP serverless environment. We leveraged cutting-edge technologies such as Quarkus Framework, Java 11/17, Google Cloud Function, Pub/Sub, Logs, and Business Metrics, and integrated Incident Alarms with Slack and OpsGenie. In the third phase, we are rewriting the Mobitraxx Android mobile apps using the React Native framework. This framework was chosen for its ability to deliver high-quality, cross-platform mobile apps with ease. Overall, our approach has yielded significant benefits, including improved scalability, reduced costs, and increased agility. This approach is recommended for organizations seeking to modernize their monolithic systems and adopt a serverless microservices architecture.
