Según el White Paper «Skies Are Becoming More Clear for Open Cloud» de IDC (noviembre 2012), el software abierto se está orientando hacia el sector privado y juega un papel esencial en el desarrollo de la nube pública, que ya domina. Las cuatro razones que IDC atribuye a esta presencia no difieren mucho de las que desde hace tiempo, potencian el uso de este tipo de soluciones en el entorno empresarial:
- Costes. Utilizar software libre permite a proveedores la creación de modelos de negocio capaces de dar respuesta a requerimientos específicos. Un coste menor a la hora de operar se debe a la capacidad del proveedor de gestionar por sí mismo la infraestructura e implementar soluciones que se adapten a sus necesidades.
- Personalización. El software libre permite aumentar la personalización de los servicios y la creación de servicios únicos. IDC recuerda en este sentido que los servicios de software en la nube son el núcleo y la propiedad intelectual del negocio de un proveedor de cloud.
- Máxima transparencia. Acceder al código fuente permite a proveedores cloud entender y depurar el software en caso de necesidad. Permite también entender cómo trabaja el software, ajustar su funcionamiento y resolver los problemas si los hubiera.
- Modelo de desarrollo colaborativo. Una de las bondades de la comunidad Linux es precisamente su condición de comunidad. Un modelo colaborativo permite construir software muy deprisa y la forma de agilizar los procesos de búsqueda de soluciones complejas. Esto incide directamente en los consumidores y proveedores, que se beneficiarán de este alto ritmo de desarrollo.
Bien es cierto que el informe de IDC está patrocinado por The Linux Foundation, pero dada la penetración de las soluciones open source en las cloud públicas, podemos darle un voto de confianza. Podéis descargar el info documento de IDC__Open_Source_Cloud_System_Software desde este enlace.
Me resulta llamativa la gráfica sobre la evolución del porcentaje de servidores cloud sobre servidores virtualizados o físicos en infraestructuras de cloud privadas. Si la predicción de IDC acierta, para 2014 confluirán las tres infraestructuras para, a partir de ese momento, empezar el despegue de la primera sobre el resto:

Respecto al estado de arte del software libre para la gestión de cloud incluyo la infografía publicada en Zenoss publicada en octubre de 2012. Los datos los obtuvieron de más de 100.000 encuestas entre gestores de infraestructuras de IT respecto al despliegue de soluciones open para cloud, sus ventajas e inconvenientes y el uso futuro que se le prevé. El informe resultante de la encuesta puede ser descargado en este enlace (requiere registro).
Las conclusiones del informe se reflejan en la siguiente infografía (podéis hacer click en ella para descargarla en PDF):
Estado de Open Source Cloud 2012. Hacer click para descargar PDF
Aspectos más destacados de la encuesta:
Respecto a la madurez de las soluciones open
- el 82,8% de los encuestados dijo que no está utilizando una nube de código abierto
- las razones para ello eran: Madurez (38,4%), falta de apoyo (30,7%) y la seguridad (28,7%)
OpenStack domina planes de adopción, pero CloudStack y Eucalyptus suben
- de aquellos que están considerando implementar una nube abierta el 63,2% busca en OpenStack, el 47% está mirando CloudStack, y el 23,5% Eucalyptus.
El futuro Open Cloud es brillante
- 57% de los encuestados dijeron que están pensando en implementar una nube de código abierto en el futuro, el 41,2% de ellos esperan hacerlo en 1 – 2 años
- Los 3 primeros aspectos de una solución Open Source Cloud considerados más importantes por los encuestados son la eficiencia y el rendimiento de la tecnología de virtualización (75,1%), el uso del proyecto de una licencia abierta (52,1%), y la calidad del ecosistema basado en la comunidad (64,3%).
