La infraestructura ya no es una ventaja competitiva  La infraestructura ya no es necesaria  Se buscan formas pago por su uso  Las formas de pago deben ser de alta granularidad  Debe ser muy elástica, ¡igual tenemos éxito!  Así aparece la Infraestructura como Servicio Diego Parrilla diego.parrilla@stackops.com 3

Las empresas empiezan a ‘infectarse’ Tecnologías que usan IaaS y no ‘hierro’ Procesos de gestión adaptadas al IaaS: metodologías ágiles. La aplicación prevalece sobre la infraestructura Ingenieros con perfiles nuevos e ideas diferentes (Devops) Diego Parrilla diego.parrilla@stackops.com 4

 SysAdmins Python developers Java developers FrontEnd developers (ExtJS) Diego Parrilla diego.parrilla@stackops.com

¿Qué es un DevOp? Conjunto de principios, métodos y prácticas para la colaboración e integración entre desarrolladores y operaciones. Combinación de ‘developer’ y ‘operations’ Operaciones programadas usando este tipo de plataformas y herramientas. De operaciones reactivas, a unas más ágiles y automatizadas. Meta: producir software y/o servicios más rápida y eficientemente. Diego Parrilla 9 diego.parrilla@stackops.com

Diseño de soluciones Los desarrolladores ganan poder en el diseño de las soluciones. La aplicación dicta sus propias necesidades de recursos. Desarrollo ‘pasa el marrón’ a Operaciones. Operaciones se defiende poniendo barreras. Actitud defensiva. Para evitarlo el ecosistema de la app debe gestionarse por software. Diego Parrilla 10 diego.parrilla@stackops.com

Mantenimiento automatizado Aparecen nuevas herramientas que automatizan tareas cotidianas de los SysAdmins Herramientas que se programan como si fuera un Framework más:  Chef,  Puppet,  Fabric… Sistemas que se gestionan como servicios mediante APIS.
