La infraestructura ya no es una ventaja competitiva
3
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 Parrilladiego.parrilla@stackops.com
Las empresas empiezan a ‘infectarse’
4
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 Parrilladiego.parrilla@stackops.com
Software to provision virtual machines on standard hardware at massive scale
Software to reliably store billions of objects distributed across standard hardware
OpenStack Compute
OpenStack Object Storage
A community creating open source software to build public and private clouds

¿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 Parrilladiego.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.
10
Diego Parrilladiego.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.
