Cloud computing is the delivery of computing resources as a service over a network. It allows users to access shared computing resources, software, and data on demand. There are three main types of cloud computing: Infrastructure as a Service (IaaS) which provides virtual machines and storage; Platform as a Service (PaaS) which provides development tools; and Software as a Service (SaaS) which provides applications. Cloud computing provides advantages like flexibility, cost savings, and ability to access resources from anywhere.

1. CLOUD COMPUTING

2. CLOUD COMPUTING
Cloud computing is the delivery of computing as a service, whereby
shared resources, software, and information are provided to computers
and other devices as a utility over a network.
It allows the employees to work remotely.
It is a on demand network access.
It helps to share a large pool of information for e.g.(networks,
services, applications, software).
It delivers information's without a direct connection to the
server.

3. PURPOSE OF CLOUD COMPUTING.
It gives large services as compare to other services.
When the demand of the same subject is more there is no
affect on this service while the servers are crash.
It saves money as compare to other computing service's.
Widespread availability irrespective of geographical precincts.
Allow for easy connectivity to servers and information sharing.

4. Applications
and services.
request
Request goes to the server
Reply
Request completed

5. PROCESS OF CLOUD COMPUTING
The request customer directly goes to the central server either
it is programme or videogames.
Central server administers the system, monitoring traffic and
client demands to ensure everything runs smoothly.
Central server follows some rules which is called protocols
and through this it helps to find the demand of customers.
When the server finds the demand of customer applications
then the request is resolve as fast as can.
The main advantage is that in large demands services better
then ordinary services.

7. There are many types of cloud computing but generally there are
three types of cloud computing which are used are in market.
Infrastructure as a service (Iaas).
Platform as a service (Paas).
Software as a service (Saas).

8.  SaaS allows a business potential to reduce it operational costs by
outsourcing hard ware and software maintenance support to the
cloud provider.
 In business model SaaS users are provided access to application
software and databases.
 SaaS is sometimes referred to as “on-demand software” and is
usually priced on a pay-per-use basis.
 SaaS providers generally price applications using a subscription
fee.

9.  Platform as a service (PaaS) is a category of cloud computing
services that provide a computing platform and a solution stack
as a service.
 In this model, the consumer creates the software using tools and
libraries from the provider.
 PaaS facilitates the deployment of applications without the cost of
buying and managing the hardware and software and provisioning
hosting capabilities.
 PaaS offerings may also include facilities for application design,
application development, testing and deployment.

10.  IaaS providers offer computers, as physical or more often as virtual
machines, and other resources.
 IaaS clouds often offer additional resources such as images in a
virtual machine image library, raw (block) and file-based storage,
firewalls, load balancers, IP addresses.
 IaaS cloud providers supply these resources on demand from
their large pools installed in data centers.

12. DEPLOYMENT MODLES
There are three deployment models of cloud computing,
Public
 Hybrid
 Private

13. Public cloud applications, storage, and other resources are made
available to the general public by a service provider.
These services are free or offered on a pay-per-use model.
 Public cloud service providers like AWS etc own and operate the
infrastructure and offer access only via Internet .

14. Hybrid cloud is a composition of two or more clouds (private,
community or public) that remain unique entities but are bound
together.
 Hybrid cloud architecture requires both on-premises resources and
off-site (remote) server-based cloud infrastructure.
Hybrid clouds lack the flexibility, security and certainty of in
house applications.

15. Private cloud is cloud infrastructure operated solely for a single
organization.
Private cloud are managed internally or by a third party and
hosted internally .
 Private cloud project requires a significant level and degree of
engagement to virtualize the business environment.
 IT will require the organization to reevaluate decisions about
existing resources.

17. Cloud computing takes very quickly in the market because of his
properties.
It is a cost effective one. It is also a one reason to take cloud
computing in the market.
It is helpful for small industries business to compete the world.
It has many applications to satisfy the customer
requirement.
