3. 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?

4. • “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)

5. 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

6. 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.
More Cloudy definitions:
Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)

8. 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.

– 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
clouds

29.  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.
