Diferentes ofertas de servicios existentes y los proveedores, la arquitectura

conceptual, sus desafíos y riesgos, criterios de adopción, y beneficios.

Este tema pretende responder preguntas como:

1. Cuáles son los principales desafíos que las empresas tienen con sus

aplicaciones y que les hacen considerar adoptar Cloud Computing?

2. Cuáles son las ofertas actuales de proveedores de Cloud Computing?

3. Cómo están los planes de aceptación de las diferentes ofertas de Cloud

Computing en los Clientes?

4. Cuáles son los riesgos que las empresas ven para adoptar Cloud Computing?

5. Qué criterios se pueden utilizar para evaluar proveedores de Cloud

Computing?

6. Qué beneficios se pueden esperar para la empresa usando Cloud Computing?

7. Cómo hacer un Caso de negocio de valor para la empresa?

8. Es una estrategia viable y que está para quedarse y brindar beneficios

empresariales o es una “moda” pasajera que los proveedores de tecnología

inventaron para seguir vendiendo?

• “Comes from the early days of the Internet where we drew the network as a cloud… we didn’t care where the messages went… the cloud hid it from us” – Kevin Marks, Google

• First cloud around networking (TCP/IP abstraction)

• Second cloud around documents (WWW data abstraction)

• The emerging cloud abstracts infrastructure complexities of servers, applications, data, and heterogeneous platforms

– (“muck” as Amazon’s CEO Jeff Bezos calls it)

Cloud Computing = an emerging IT development, deployment and delivery model, enabling real-time delivery of products, services and solutions over the Internet (i.e., enabling cloud services)

IDC, 2008

Cloud Computing = computing as a style of computing in which scalable and elastic (massively scalable) IT-enabled capabilities are delivered as a service to external customers using Internet technologies.

Gartner Group, 2009 (updated)Cloud computing = a pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption.

Forrester, 2009

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

NIST Cloud Research Team, 2009

Cloud computing is using the internet to access someone else’s software running on someone else’s hardware in someone else’s data center while paying only for what you use.

Software as a service (SaaS): Software deployed as a hosted service and accessed over the Internet.

Platform as a service (PaaS): Platforms that can be used to deploy applications provided by customers or partners of the PaaS provider.

Infrastructure as a service (IaaS): Computing infrastructure, such as servers, storage, and network, delivered as a cloud service, typically through virtualization.

Anything as a service (XaaS): Acronym used to express that anything can be delivered as a service.

• Private cloud (internal)

– enterprise owned or leased

• Community cloud

– shared infrastructure for specific community

• Public cloud (external)

– Sold to the public, mega-scale infrastructure

• Hybrid cloud– composition of two or more

Reduced Total Cost of Ownership: Cloud technology is paid incrementally, saving organizations money.

Increased Scalability and Reliability: leverage the massive international infrastructure of the cloud provider. This brings benefits of backup, reduced latency, fault tolerance and the ability to support peak demands.

Highly Automated : No longer do IT personnel need to worry about keeping software up to date.

Flexibility: Cloud computing offers much more flexibility than past computing methods.

Allows IT to Shift Focus: No longer having to worry about constant server updates and other computing issues, government organizations will be free to concentrate on innovation.

Two Scenarios:- On Premise- Cloud Computing

For each scenario:

Benefits- Savings on upgrades & hardware renewal- Savings on servers administration- Reduced time to market

Costs- OPEX

- Hardware- Software

- Operational costs due to Cloud Computing- Security- Monitoring- Compliance- Operational efficiency

Leveraging Cloud Computing needs someArchitecture definitions: Public or Private

Cloud for “virtual-tructure”? What PlatformComputing will your Applications

Architecture Team will use?

A Clear definition of platform, services and value proposition is

key

What expectations should I have and what

commitment I can do for my Company if using Cloud Computing?

Remember to use Cloud Governance and complete your Business Case before adopting

Cloud Computing

When I deploy an Application I need to

decide Where (hardware) and What (software) I will use…

How to convince my Company to use Cloud Computing?
