Migración de un módulo de una aplicación Monolítica a Microservicios siguiendo el enfoque DevOps y de CICD. Caso de estudio FestumApp y su despliegue en Azure

Abstract

Abstract: FestumApp, an application for managing social events in Latin America, has limitations due to its monolithic architecture that make it difficult to scale, integrate changes, and support continuous deployments. To improve this, it proposes migrating functions to a microservices architecture using DevOps, CI/CD, and deploying on Azure. Domain-Driven Design was applied, identifying six bounded contexts and developing two microservices: Event Management and Ticket Management. Clean Architecture, NestJS, Prisma ORM, and PostgreSQL were used, along with asynchronous communication via NATS to decouple components. Continuous delivery was automated with Azure DevOps by building Docker images, publishing them to Azure Container Registry, and deploying them to Azure Kubernetes Service. The proposal was validated through load tests, showing improved load handling and costs of USD 1.15 per 100,000 requests, with a monthly projection of USD 45.08. The security evaluation indicated controls in four of five critical layers, confirming the viability and sustainability of the migration in a cloud-native environment.
