3. Definition
Cloud computing is the on-demand availability of computer system resources,
especially data storage and computing power, without direct active management
By the user.
Storing the data in some physical locations (data centers), and accessing it from
any point of the world through the internet.

4. The idea of cloud computing came from several people. Professor Jhon McCarthy of MIT and
Dr. J. C. R. Licklider, director at the U.S. Department of Defense Advanced Research Project
Agency (ARPA), are generally given credit for developing the concept. In 1961, McCarthy
proposed selling computing resources (such as data processing) and software as a service
through a public utility, similar to how water, sewer, and electrical power are made available to
the public. This idea was based on hosting services and software on a mainframe computer. In
an April 25, 1963, memo, “Members and Affiliates of the Intergalactic Computer
Network,”Dr.Licklider proposed interconnecting programs and data to share resources. In 1968,
the ARPA Program Plan No.723, Resource Sharing Computer Network, was initiated to engineer
a solution of sharing networked resources. It then developed into the Advance Research
Projects Agency Network which later become the internet.
History
5. • Buy physical servers.
• Keeping the peak traffic in mind
buy more servers.
• Monitoring and Maintenance of
your servers.
• This setup is expensive.
• Takes lot of time to provision.
• Can’t access from other location.
• Risk od data loss.
• Wastage of time.
• Pay whether use it or not.
• Rent virtual servers
• No need. Automatically scale
up & scale down as per traffic
• Taken care by cloud provider.
• Cheapest.
• On-demand .
• Access from any place in
world.
• Data will never loss.
• Save your time.
• Pay only for what you use.
Before cloud vs after cloud
6. Many cloud service providers (CSPs) and products are available. CSPs use a variety of approaches and systems to
build their cloud systems, such as servers using distributive processing methods with data farms for storage or
mainframes running OSs as virtual machines. The following are some CSPs and cloud applications:
• Salesforce: offers a variety of cloud services, including automation and CRM, cloud application development,
was site marketing .
• IBM Cloud: provides cloud development and mobile applications for several platforms.
• CISCO Cloud: has cloud application for a wide assortment of businesses, ranging from enterprise and mid-size
businesses to resellers of cloud services.
• Google cloud storage: offers virtual machines with tools for analyzing large data sets.
• Amazon: offers a web service run from the cloud that allows scalability.
• Microsoft Azure: it provides a range of cloud services, including compute, analytics, storage and networking.
Cloud vendors
7. SAAS
• Fullform of Saas isSoftware as a service.
• Also known as on demand software.
• It is a software delivery model in which software and its associated data arc hosted
centrally and accessed using a thin dint , usually a web browser over the internet.
• SAAS is a method for delivering software that provides remote access to software as a
web based service. The software service can be purchased with a monthly fee and pay as
you go.
Cloud Deployment Models
8. PAAS
• Paas fullform is platform as a service.
• It is a cloud service where customer gets set of application and product development tool hosted
on the providers infrastructure.
• Consumer doesnot control, run or manage the underlying cloud infrastructure, including servers,
OS, storage, security, devices, network but has control over deployed application and possibly
also configurations of the hosting environment.
Cloud Deployment Models
9. IAAS
• IAAS fullform is Infrastructure as a service.
• It is a service/model in which you as a customer, pay for the resources (such as computepower, memory,
storage, bandwidth, security devices, load balancer etc) kept at the providers facility or wherever the
provider keeps it hardware.
Cloud Deployment Models
10. Cloud deployment servers
• Public cloud: different organisations shares the same hardware,
storage and network device.
• Private cloud: typically infrastructure used by a single organisation.
• Hybrid cloud: an organisation makes use of interconnected private
and public cloud infrastructure.
• Community cloud: this model supports multiple organisations sharing
computing resources.
11. Back-up & restore data
Improved collaboration
Excellent accessibility
Low maintenance cost
Mobility
Unlimited storage capacity
Internet connectivity
Vendor lockin
Limited control
