Cloud computing refers to using computing resources that are delivered as a service over the Internet. It allows users to access applications, databases, and storage from anywhere as long as they have an Internet connection. There are different types of cloud deployment models including public, private, hybrid, and community clouds. Cloud services can be delivered through infrastructure as a service, platform as a service, or software as a service models. Cloud storage specifically refers to storing data and files on servers maintained by a cloud computing provider that users can access through the public Internet or private network connection.
3. The cloud refers to application,
services and data storage on
the internet.
“Cloud Computing” simply
means the use of computing
resources as a service
through internet.
With this, users can access database resources
via internet from anywhere, for as long as they
need, without worrying about any maintenance
or management of actual resources.
4. Cloud computing is both,
combination of software and
hardware based computing
resources delivered as a
networked service.
These applications and
resources can be accessed
using a simple front end
interface such as web-
browser.
Thus enabling users to access
resources from any client
device including notebooks,
desktops and mobile devices.
7. Cloud architecture is the way technology
components combine to build a cloud, in
which resources are pooled through
virtualization technology and shared across a
network.
8. The cloud computing architecture comprises two
fundamental components, i.e. frontend and
backend.
Frontend works as a client in such architecture
and communicates with the backend via a
network or internet. In the cloud computing
architecture, the client-side or frontend is visible
to the end-user. The frontend sends queries to
the backend via the middleware.
The backend protects the data and respond to
the queries asked by the frontend. The backend
is a bigger part of the whole cloud computing
architecture as shown:

10. There are certain services and models
working behind the scene making the cloud
computing feasible and accessible to end
users. Following are the working models of
cloud computing:
1. Deployment Models
2. Service Models
11. Deployment models define the type of access
to the cloud, i.e how the cloud is located?
Cloud can have any of the four types of
access:
1. Public
2. Private
3. Hybrid
4. Community
12.
13. • Allows system and services to be easily
accessible to general public.
• It may be less secure because of itf
openness, eg., e-mail.
Public
• Allows systems and services to be
accessible exclusively for
organization’s benefit.
• Offers increased security because of its
private nature.
Private
14. • Mixture of public and private cloud.
• However, the critical activities are
performed using private cloud and
non critical activities, using public
cloud.
Hybrid
• Allows systems and services to be
accessible by group of organizations.
• It may be owned ,managed and
operated by one or more org. in the
community.

19. The three Cloud Service Models are as
follows:
1. Infrastructure as a Service (IaaS)
2. Platform as a Service (PaaS)
3. Software as a Service (SaaS)
23. Cloud storage is a cloud computing model that enables storing
data and files on the internet through a cloud computing provider
that you access either through the public internet or a dedicated
private network connection.
The provider securely stores, manages, and maintains the storage
servers, infrastructure, and network to ensure you have access to
the data when you need it at virtually unlimited scale, and with
elastic capacity. Cloud storage removes the need to buy and
manage your own data storage infrastructure, giving you agility,
scalability, and durability, with any time, anywhere data access.
24. Cloud storage is delivered by a cloud services provider that
owns and operates data storage capacity by maintaining
large datacenters in multiple locations around the world.
Cloud storage providers manage capacity, security, and
durability to make data accessible to your applications over
the internet in a pay-as-you-go model.
Typically, you connect to the storage cloud either through
the internet or through a dedicated private connection, using
a web portal, website, or a mobile app.
When customers purchase cloud storage from a service
provider, they turn over most aspects of the data storage to
the vendor, including capacity, security, data availability,
storage servers and computing resources, and network data
delivery.
25. Cloud Storage
• Create an Account User
name and password.
• Content lives with the
account in the cloud.
• Log onto any computer
with Wi-Fi to find your
content.
26. Download a cloud based app to on your
computer.
The app lives on your computer.
Saves files to the app.
When connected to internet it will sync with
the cloud.
The cloud can be accessed from any Internet
Connection.
27. There are three main cloud storage types:
1. Object storage,
2. File storage,
3. Block storage.
Each offers its own advantages and has it
own use cases.
