Efectos De La Cultura DevOps
La adopción de la cultura DevOps, herramientas y practicas ágiles de ingeniería tienen, por sobre todas las cosas, el lindo efecto de incrementar la colaboración entre los roles de desarrollo y operaciones.
Uno de los principales problemas del pasado (pero también hoy en día en algunas realidades) es que el equipo de desarrollo no estaba interesado en la operación y el mantenimiento de un sistema una vez que se entregó al equipo de operaciones, mientras que este último no estaba realmente consciente de los objetivos de negocio, y por lo tanto, reacios a satisfacer las necesidades operativas del sistema (también denominados “caprichos de los desarrolladores”)
