The document provides a comprehensive overview of cloud computing, including its definition, history, benefits, and various models. It details how cloud computing delivers services over the internet through third-party management and distinguishes between public, private, and hybrid cloud models. Key advantages include cost savings, accessibility, and scalability, while limitations involve dependency on internet connectivity and security concerns.

● Pros and cons of cloud computing

3. What is Cloud?
The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something which is
present at remote location.

4. What is Cloud Computing?
● In Simple term, cloud computing is the delivery of computing services like servers, storage, database,
networking, software, analytics and more-over the internet (cloud)
● Cloud computing consists of hardware and software resources made available on the internet as they
are managed by the third party services. These services typically provides access to advanced software
application, high end networks of the server computers

5. History
● Around 1950 the mainframe computing concept evaluate
● Around 1970 virtual environment concept created
● In 1999, Salesforce.com started delivery of applications to users using simple website
● In 2002 Amazon provide first public cloud AWS (Amazon Web Service) providing services like storage, computation
● In 2009 Google Apps also started to provide cloud computing enterprise application
● In 2009, Microsoft launched Microsoft Azure and companies like Oracle, HP have all joined

6. Cloud Computing Key Players

7. Benefits of Cloud Computing
● Drive down costs
● Accessibility
● Productivity
● Scalability
● Access to automatic updates
● Business Continuity (Backup and Restore)
● Pay structure

8. Examples of cloud computing
Email: Web-based email services like Gmail, yahoo and Hotmail deliver cloud computing service. User can
access their email from any browser or mobile or any portable device
Office productivity Software: Office 365, zoho or Google docs etc. These software allows keep and edit your
documents online
Storage: One Drive, Google Drive, iCloud and Dropbox

9. Common Cloud Characteristics
● On Demand Service
● Broad Network Access
● Multi-Tenancy (Resource Pooling)
● Rapid Elasticity
● Measured Service

10. Cloud Computing Architecture
As the term architecture states, proper designing and planning of something so is the cloud architecture in
cloud computing. It is divided into two parts, the front end, and the back end.
Front end: You can count all the endpoint devices, services, and applications in this category such as web
servers, User Interface or client-side interface, network, mobile, laptops, etc. For example, Google, Firefox,
and Microsoft Edge are all front-end cloud services.
Back end: Everything else that doesn’t come in the front end is categorized in the back end like servers, large
storage devices, management of applications and services, security, etc. For example, Microsoft Azure,
Google Cloud, and Amazon Web Services are all back-end cloud services.

12. Cloud Models
● Deployment Model
● Service Model

13. Deployment Model
A Cloud Deployment model represents a specific type of cloud environment, primarily distinguished by
ownership, size and access
Three deployment models

14. Public Cloud: It is open to public

15. Private Cloud: Which is managed and used internally within organization

16. Hybrid Cloud: Combination of Public and Private Cloud

17. Service Models: There are 3 different approaches to cloud-based services
● Infrastructure as a Service [IAAS]
● Platform as a Service [PAAS]
● Software as a Service [SAAS]

23. Benefits of Cloud Computing
● Reduced Hardware equipment for end-users
● Improved performance
● Instant Software updates
● Accessibility
● Metered Services
● Less Expensive
● Improved Disaster Recovery

24. Limitation of Cloud Computing
● Require Good Internet connectivity
● Security
● Limited control on Infrastructure
