This document provides an overview of cloud computing concepts including definitions, characteristics, service models, deployment models and examples. It defines cloud computing according to NIST as a model for enabling network access to configurable computing resources that can be provisioned with minimal management effort. The key characteristics are on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. The common service models are SaaS, PaaS and IaaS. Deployment models include private, public and hybrid clouds. Examples of applications and potential benefits are also provided.

3. Cloud is a Strategy
ü Cloud is not a technology
ü Organizations are using the Cloud to develop and deploy
applications to support the business and open up new innovative
opportunities and new revenue streams
ü Companies:
ü are asking for what types of cloud computing models are best
suited to solve their business problems
ü are using the Cloud to make the business faster and to build new
business models
Understanding the essentials of
Cloud Computing

4. There are several Cloud definitions provided by NIST, Gartner
and Technology Vendors.
“Cloud computing is a model for enabling ubiquitous, 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.This cloud model is
composed of five essential characteristics, three service models, and four deployment
models “ NIST definition - http://csrc.nist.gov/publications/nistpubs/800-145/SP800-145.pdf
Cloud definition

5. On-demand self-service. A consumer can unilaterally provision computing capabilities,
such as server time and network storage, as needed automatically without requiring human
interaction with service providers.
Broad network access. Capabilities are available over the network and accessed through
standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g.,
mobile phones, tablets, laptops, and workstations).
Resource pooling. The provider’s computing resources are pooled to serve multiple
consumers using a multi-tenant model, with different physical and virtual resources
dynamically assigned and reassigned according to consumer demand.
Rapid elasticity. Capabilities can be elastically provisioned and released, in some cases
automatically, to scale rapidly outward and inward commensurate with demand.
Measured service. Cloud systems automatically control and optimize resource use by
leveraging a metering capability at some level of abstraction appropriate to the type of
service (e.g., storage, processing, bandwidth, and active user accounts).
Cloud characteristics

6. Software as a Service (SaaS). The capability provided to the consumer is to use the
provider’s applications running on a cloud infrastructure.The applications are accessible from
various client devices through either a thin client interface, such as a web browser (e.g., web-
based email), or a program interface.
Platform as a Service (PaaS).The capability provided to the consumer is to deploy onto
the cloud infrastructure consumer-created or acquired applications created using
programming languages, libraries, services, and tools supported by the provider.
Infrastructure as a Service (IaaS). The capability provided to the consumer is to
provision processing, storage, networks, and other fundamental computing resources where
the consumer is able to deploy and run arbitrary software, which can include operating
systems and applications.
Cloud service models

7. Private cloud. The cloud infrastructure is provisioned for exclusive use by a single
organization comprising multiple consumers (e.g., business units). It may be owned, managed,
and operated by the organization, a third party, or some combination of them, and it may
exist on or off premises.
Community cloud. The cloud infrastructure is provisioned for exclusive use by a specific
community of consumers from organizations that have shared concerns (e.g., mission,
security requirements, policy, and compliance considerations). It may be owned, managed,
and operated by one or more of the organizations in the community, a third party, or some
combination of them, and it may exist on or off premises.
Public cloud. The cloud infrastructure is provisioned for open use by the general public. It
may be owned, managed, and operated by a business, academic, or government organization,
or some combination of them. It exists on the premises of the cloud provider.
Hybrid cloud. The cloud infrastructure is a composition of two or more distinct cloud
infrastructures (private, community, or public) that remain unique entities, but are bound
together by standardized or proprietary technology that enables data and application
portability.
Cloud deployment models
CSP = Cloud Service Provider
CSB = Cloud Service Broker
ISV = Independent Software vendor
“The ITValue Chain is changing dramatically, there are 3 mains actors coming.
TechnologyVendors providing technology to realize cloud services, Cloud Service Providers
with mission to realize Cloud Services and Cloud Service Brokers with the mission to
aggregate, integrate and enable cloud services to end users.”

9. Cloud dematerialization example
New Cloud Applications are coming to allow de-materializzation of business process using
Tablets and new mobile devices. Digital signature available using anyTablet can be integrated
by web-services with applications like ECM or Document Management.This will allow
organizations to reduce costs in printing, paper and to become more productive and green.

10. Video in the Cloud: enables new business models
Working in mobility using any device
internationalization of business!
Remote-care,Video-Data-Sheet,
Traning online, Meeting online, ..
Video Communication in the Cloud as a service allows organizations to join collaborative meeting using any
device from any location , introducing new way to do business. For example a smartphone can be used as a
video camera to do “remote monitoring” or a PC to do remote healthcare.Any Company can have a
personal video store to be used like a CompanyYou-Tube for Communication or to share any kind of
information (video data sheets, training on-demand, executive communications, ..).

11. Cloud Collaboration
web-conferencing
audio-conferencing
Sync Share
Unified Communication
Cloud is enabling new collaboration tools.Web-conferencing is used in order to share a content like a
presentation or any document. Unified Communication as a Service is going to be the new IP-PBX in the
Cloud Era. Sync and Share Applications are coming to manage the BYOD paradigm (BringYour Own Device)
allowing to employees to use personal and business applications using any device.Video Communication has
the goal to emulate the personal presence, and someVendor call it:“PersonalTele-presence”.

12. Social is the new Normal!
Social Networks are dramatically changing the way people interact and also they are introducing new way to
implement lead generation in Marketing Processes. We see two areas impacting in the Business:
1. Social Intranet , the corporate Intranets are introducing Social tools to improve the internal collaborations,
reducing the number of emails
2. Social Portals to engage with customers and partners in a different way more productive and innovative,
introducing alsoWeb 2.0 tools like chat, wiki pages and forums. Social Networks like Linkedin and
Facebook are going to be used like channels to setup lead generations processes in multi-channel
marketing strategies.

Cloud Architecture example
This is an example of a real project where
the CIO and General manager wanted a
flexible and scalable architecture in order
to introduce Unified Communication and
Collaboration services over a Public Cloud
Infrastructure.

Cloud moves Capex to Opex
A Cloud Project has impact also in the cash flow, reducing Capex investments and moving costs to Opex.
In this way a CIO or Business Decision Maker can scale faster from few resources to an Enterprise class
environment in a very simple and fast way, reducing risks and time to market.
In this way any you improve the “business agility” of your Company.
