Integración Continua y Despliegue Continuo. Automatización del proceso de testing, build y despliegue de aplicaciones.
CI/CD (Continuous Integration / Continuous Deployment) es la práctica de automatizar la integración, testing y despliegue de código. CI (Integración Continua): - Merge frecuente de código - Build automático - Tests automatizados - Detección temprana de errores CD (Despliegue Continuo): - Despliegue automático a staging/producción - Rollbacks automáticos - Feature flags para releases graduales Herramientas: GitHub Actions, GitLab CI, Jenkins, CircleCI.
