Chapter 7 discusses the origins and architecture of cloud computing, tracing its roots back to concepts introduced by John McCarthy in 1961. It outlines various service models, including Software as a Service, Platform as a Service, and Infrastructure as a Service, as well as deployment models like public, private, hybrid, and community clouds. The chapter emphasizes the significant role of data centers in supporting cloud services and compares the evolution of cloud computing to that of electricity in the industrial age.

2. Origin of the Cloud
• In 1961 John McCarty, father of artificial intelligence at the Massachusetts
Institute of Technology, announced the term Time Share Technology for the first
time, which is the essence of what we now call Cloud Computing. However, it
was only until 1999 when Salesforce.com began to deliver business applications
through web page

3. • Currently Google, Amazon, Microsoft and several foreign companies dedicated to
offering a wide range of services related to the cloud, the term Cloud Computing
represents a new model in computing, because the cloud represents the evolution in
technologies in the construction of infrastructure for information technologies.

4. Composition of the Cloud
• INFRASTRUCTURE
• PLATFORM
• SOFTWARE
From the composition of the cloud there are service models, this is possible thanks to
virtualization technologies, as the bandwidth and the millions of servers with great
processing capacity and transfer speed, together with the proliferation and diversification of
electronic devices .

5. • It is a collection of network computerization resources, which clients of the cloud can
access through the network, based on the client-server model.
• The cloud itself is a set of hardware and software, storage, services and interface that
facilitate the entry of information as a service
Definition of the Cloud

6. • MODELS OF SERVICE:
• Software as a Service: The user lacks control over the cloud infrastructure, such as servers,
operating system, storage, even on their own applications, except for the customization
options to which users have access. An example of this is web emails like Gmail and Yahoo.
Cloud Models

7. • MODELS OF SERVICE:
• Platform as a Service: The user is allowed to deploy own applications created using
languages and tools supported by the provider, therefore the user has control over the
applications but not of the entire underlying infrastructure. Normally, the supplier offers tool
kits for the development of applications, distribution channels and payment of the same.
Cloud Models

8. • MODELS OF SERVICE:
• Infrastructure as a Service: The capacity given to the consumer by providing processing,
storage, networks and other computing resources. The consumer does not manage or control
the infrastructure in general but has control over operating systems, deployed applications
and storage; However, the biggest problems that this type of services has, as well as the cloud
in general, is the security and privacy of the information.
Cloud Models

9. • MODELS OF DEPLOYMENT
• Public Cloud: It is operated, managed and hosted by a provider from one or more within data,
the management of security and operations is controlled by the provider of the services as
well as the offer also; This model obeys the standard model of cloud computing.
• Private Cloud: the management and operation as well as the security and supply of storage is
controlled by the organization because it is the one that assembles the infrastructure and
gains all the advantages of virtualization. They are also known as internal cloud, and is similar
to an intranet or private data center, is used in areas where information is strictly confidential
or high context in organizations.
Cloud Models

10. • MODELS OF DEPLOYMENT
• Hybrid Cloud: It is the combination of a public and private cloud where organizations share
information to the public and their employees as the case may be, but the sensitive data is
clearly charged to the private cloud.
• Community Cloud: It is one whose infrastructure is shared by several organizations, and
supports a specific community that has shared characteristics and can be partitioned in such a
way that one part can be public or another private as decided by the participating
organizations of the same.
Cloud Models

11. • They are considered as the factories of the 21st century, it is a phenomenon compared
to that of electricity in such a way that they are made up of powerful industrial
environments.
• They are defined as environments used to house computer systems and associated
components includes redundant power supplies and is used for backup copies,
connections and redundant data communications, environmental controls and security
devices
