Cloud computing relies on sharing computing resources over the internet rather than having local servers. It allows users to access applications, servers, and storage from any device. There are three main types of cloud models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides on-demand access to computing resources like storage, networking, and servers. PaaS provides platforms for developing and running applications without managing the underlying infrastructure. SaaS provides access to applications over the internet without installation or maintenance of software.

3. What is Cloud?
• The term Cloud refers to Network or Internet.
• Cloud is something, which is present at remote
location. Cloud can provide services over public
and private networks, i.e., WAN, LAN or VPN.

4. What Is Cloud Computing
• Cloud computing is a type of computing that
relies on sharing computing resources rather
than having local servers or personal devices to
handle applications.
• Cloud computing means "a type of Internet-
based computing," where different services such
as servers, storage and applications are
delivered to an organization's computers and
devices through the Internet.

1. Public Cloud
2. Private Cloud
3. Hybrid Cloud

7. Public CloudPublic Cloud
Public Cloud allows systems and services to be easily
accessible to general public. Company offer cloud
services via Internet.
Features:
a. Flexibility
b. Location Independence
c. Cost Effective
d. Reliability

8. Private CloudPrivate Cloud
Private Cloud allows systems and services to be accessible
within an organization. The Private Cloud is operated only
within a single organization.
Features:
a. High Security and Privacy
b. More Control

9. Hybrid CloudHybrid Cloud
A combination of public cloud storage and private cloud storage
where some critical data resides in the enterprise's private cloud
while other data is stored and accessible from a public cloud storage
provider.
Features:
a. capability
b. Reliability
c. security
d. control

10. Cloud Service ModelsCloud Service Models
There are mainly 3 service models given as:
1. Software as a Service (SaaS)
2. Platform as a Service (PaaS)
3. Infrastructure as a Service (IaaS)

11.  Defined as service-on-demand, where a provider will
license software tailored.
 In the SaaS model, cloud providers install and operate
application software in the cloud and cloud users access
the software from cloud clients. Cloud users do not
manage the cloud infrastructure and platform where the
application runs. This eliminates the need to install and
run the application on the cloud user's own computers,
which simplifies maintenance and support.

12. PaaSPaaS
In the PaaS model, cloud providers deliver a
computing platform typically including operating system,
programming language execution environment, database,
and web server. Application developers can develop and run
their software solutions on a cloud platform without the cost
and complexity of buying and managing the underlying
hardware and software layers.

13. IaaSIaaS
In the most basic cloud-service model, providers of IaaS
offer computers physical or (more often) virtual machines
and other resources. IaaS clouds often offer additional
resources such as a virtual-machine disk image library,
raw (block) and file-based storage, firewalls, load
balancers, IP addresses, virtual local area networks
(VLANs), and software bundles.IaaS-cloud providers
supply these resources on-demand from their large pools
installed in data centers.

16. Cloud StorageCloud Storage
Cloud storage means "the storage of data online in the cloud,"
wherein a company's data is stored in and accessible from
multiple distributed and connected resources that comprise a
cloud.
Cloud storage can provide following benefits
a) accessibility and reliability;
b) rapid deployment;
c) strong protection for data backup, archival and disaster.
