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

Coste por uso


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

SaaS, PaaS, IaaS ?!!? Los “xaaS”

Cloud Computing (Taxonomía)

http://cloudtaxonomy.opencrowd.com/taxonomy/


Las empresas hacia el cloud computing

Las empresas dispondrán de una infraestructura dedicada para algunos propósitos y consumirán servicios On Demand obtenidos de la nube para otros.


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.


¿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.

•Extends network to the VM

•Consistent services

•Coordinated, coherent management

VMotion•VMotion may move VMs across

physical ports—policy must follow

• Impossible to view or apply policy to locally switched traffic

•Cannot correlate traffic on physical links—from multiple VMs

I/O Consolidation with FCoE


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...


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...


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...


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.


Unified Fabric – simplifies infrastructure using industry standards.

Embedded Management – one management domain simplifies management framework.

Large Memory Footprint – unique memory architecture allows for faster performance and lower costs for large RAM servers.

Virtualization Adapter – improves performance and reduces NIC infrastructure.

Service Profiles – allows for stateless computing, mobility, rapid provisioning and rapid recovery.
