Cloud Computing (Definiciones)
Wikipedia:
“Cloud computing es un paradigma que permite ofrecer servicios de computación a través de Internet”
ServePath:
“The use of a 3rd party service to perform computing needs on a publicly accessible IP basis. Cloud computing services are usually performed in consolidated Data Centers to keep costs low while improving overall utilization”
Elementos habituales en todas las definiciones:
Acceso a través de Internet (la “nube”)
Virtualización
Escalabilidad

Cloud Computing: Conceptos
Definimos a “Cloud Computing” como un estilo de computación donde los recursos de IT son:
Brindados a los clientes como un servicio utilizando tecnologías de Internet.Masivamente escalables.De alcance global.Distribuibles dinámicamente, “a demanda” en cantidad y calidad medibles.Asignados Just in TimeServicios a múltiples clientes que comparten los mismo recursos. (Multi-Tenant)Se paga solo por el servicio que se utiliza.
La virtualización es el fundamento para avanzar hacia los servicios del cloud computing

SaaS (Software as a Service): Significa una sola instancia de un software o aplicación que corre en la infraestructura del proveedor y sirve a múltiples organizaciones de clientes. Ejemplo: Salesforce.com
PaaS (Plataform as a Service): Es la encapsulación y la abstracción de un ambiente de desarrollo. Ejemplo: Amazon EC2
IaaS (Infraestructura as a Service): Es un medio de entrega de almacenamiento y capacidades de cómputo como servicios estandarizados en la red. Ejemplo: rackspacecloud.com

Virtualización
La Virtualización consiste en la abstracción de los recursos físicos existentes en un equipo informático para poder correr sobre el mismo equipos virtuales.
Cada uno de estos equipos virtuales ve un servidor completo, interactuando con el mismo a través de la tecnología de virtualización.
Business and Technology Working as One
¿Qué se puede virtualizar?
Servidores (VMs, la nueva unidad atómica en el DC)
Networking. (Switches, Load Balancers)
Seguridad. (Firewall)
Almacenamiento. (Storage)
Escritorios de usuarios. (Virtual Desktop)
Aplicaciones. (Ej: Paquete Office)

Beneficios de la virtualización
Reduccion de los esfuerzos de administración:
Menores costos operacionales
Menos servers para administrar.
Rapid deployment
Ahora 1-6 Semanas (Compra, setup, software, test).
Con la virtualización se puede reducir a horas.
Reducción en los costos de infraestructura y servidores.
Mejora en la utilización de los recursos.
Incrementa y mejora la disponibilidad.
Herramientas para mejorar la seguridad.

Next Generation Data Center
A medida que la infraestructura IT se vuelve mas compleja, los requisitos de IT cambian de gerenciar operaciones técnicas a operaciones de servicios. Esto plantea la necesidad de transformación del DC.
Cuatro fuerzas evolutivas
Están dando forma al NGDCLa nueva generación de Data Centers
será…..
• Una infraestructura provisionada dinámicamente por medio del uso de capacidades automatizadas soportando el proceso de negocio de la compañía.
• Servicios de tecnología construidos sobre infraestructura virtual.
• Procesos estandarizados.
• Arquitecturas tecnológicas que permitan consolidar recursos de IT.

Top of Rack (ToR)• Typically 1-RU servers
• 1-2 GE LOMs
• Mostly 1, sometimes 2 ToR switches
• Copper cabling stays within rack
• Low copper density in ToR
• Higher chance of East-West traffic hitting aggregation layer
• Drives higher STP logical port count for aggregation layer
• Denser server count
Data Center Access Layer Options
Middle of Row (MoR) (or End of Row)• May be 1-RU or multi-RU servers
• Multiple GE or 10GE NICs
• Horizontal copper cabling for servers
• High copper cable density in MoR
• Larger portion of East-West traffic stays in access
• Larger subnets less address waste
• Keeps agg. STP logical port count low(more EtherChannels, fewer trunk ports)
• Lower # of network devices to manage

Business and Technology Working as One
NON-Unified Fabric – Phase 0
A Segregated LAN and SAN…
In existing architectures, LAN and SAN connectivity is segregated directly from the Servers, where NICs and HBAs connect into Ethernet switches and Fibre Channel Fabrics. This may result in excess of 8+ cables to/from each physical server
In Ethernet, redundancy relies upon technologies such as Spanning Tree Protocol to provide a loop-free topology...
Business and Technology Working as One
Unified Fabric – Phase 1
A Unified Fabric in the Access…
The Nexus 5000 allows for the consolidation of Ethernet and Fibre Channel to be carried across the same physical piece of cable - Ethernet
Leveraging standards-based FCoE, the Nexus 5000 is able to provide direct FCoE connectivity from the Server through a Converged Network Adapter (CNA) to the Nexus 5000.
The Nexus 5000 is then able to perform Ethernet switching for regular Ethernet frames, and Fibre Channel forwarding for FC frames...
Business and Technology Working as One
Unified Fabric – Phase 2
Unified Fabric in the Data Center
Once FCoE-enabled modules become available on the Nexus 7000 or the MDS 9500 series platforms, multi-hop FCoE topologies may be possible by retaining FCF capabilities across the different platforms
Additionally, with the introduction of direct FCoE
attached targets, these may also be directly
connected to any of these FCoE-enabled devices...
Business and Technology Working as One
Key Benefits of Unified Fabric
Reduce overall DC power consumption by up to 8%. Extend the lifecycle of current data center.
Wire hosts once to connect to any network - SAN, LAN, HPC. Faster rollout of new apps and services.
Every host will be able to mount any storage target. Drive storage consolidation and improve utilization.
Rack, Row, and X-Data Center VM portability become possible.
