WHAT IS CLOUD?
"The cloud" refers to servers that are accessed
over the Internet, and the software and
databases that run on those servers. Cloud
servers are located in data centers all over the
world. By using cloud computing, users and
companies don't have to manage physical servers
themselves or run software applications on their
own machines.

CLOUD COMPUTING
◦ A simple definition of cloud computing involves
delivering different types of services over the
Internet. From software and analytics to secure
and safe data storage and networking resources,
everything can be delivered via the cloud.
◦ Cloud Computing provides us a means by which
we can access the applications as utilities, over
the internet. It allows us to create, configure,
and customize the business applications online.

CHARACTERISTICS OF CLOUD COMPUTING
The characteristics of Cloud
Computing are:
1.Great Availability of
Resources
2.On-demand Self-service
3.Easy Maintenance
4.Large Network Access
5.Availability
6.Automatic System
7.Economical
8.Security
9.Pay as you go

Characteristics of Cloud Computing
• On-Demand Self-Service: It is one of the
important and valuable features of Cloud
Computing as the user can continuously
monitor the server uptime, capabilities, and
allotted network storage.
• Large Network Access: The user can access the
data of the cloud or upload the data to the
cloud from anywhere just with the help of a
device and an internet connection. These
capabilities are available all over the network
and accessed with the help of internet.
• Availability: The capabilities of the Cloud can
be modified as per the use and can be
extended a lot. It analyzes the storage usage
and allows the user to buy extra Cloud
storage if needed for a very small amount.

◦ Resource pooling: Multiple tenants can share the
same space, and resources can be assigned, re-
assigned, and distributed as needed.
◦ Rapid elasticity: Cloud can grow and shrink as much
as possible without affecting any of its users or
their information. For example, if your business is
experiencing peak traffic, the cloud can expand to
accommodate all the new requests.
◦ Economical: It is the one-time investment as the
company (host) has to buy the storage and a small
part of it can be provided to the many companies
which save the host from monthly or yearly costs.
◦ Security: Cloud Security, is one of the best
features of cloud computing. It creates a snapshot
of the data stored so that the data may not get
lost even if one of the servers gets damaged.

There are mainly 3 types of cloud
computing:
1.Public cloud
2.Private cloud
3.Hybrid cloud

Types of Cloud Computing
1.Public Cloud : Public cloud services are best for development systems and
web servers. Your cloud computing provider will give you a slice of their
digital space that they must share with other tenants.
2.Private Cloud : Private cloud platforms are typically built in-house, and
they belong to you and your business. They can also be configured in
a third-party data center and still provide an advanced level of privacy.
3.Hybrid Clouds : Hybrid cloud are the best of both worlds. If you are using
a hybrid cloud, you can control an internal database and use the public cloud
when needed. There might be times when you will need to move data and
applications from the private cloud to the public cloud, such as scheduled
maintenance, blackouts, and natural disasters

◦ SaaS stands for Software as a Service,
provides a facility to the user to use
the software from anywhere with the
help of an internet connection. It is also
known as software on demand. The
remote access is possible because of
service providers, host applications and
their associated data at their location.
There are various benefits of the SaaS
as it is economical and only the user has
to pay for some of the basic costs such
as licensing fees, installation costs,
maintenance fees, and support fees.
Some of the examples of SaaS are
Yahoo! Mail, Hotmail, and Gmail.

◦ PaaS stands for Platform as a
Service. This helps the user by
providing the facility to make,
publish, and customize the software
in the hosted environment. An
internet connection helps to do it. It
also has several benefits such as it
has lower costs and only the user has
to pay for the essential things. The
host of a PaaS has the hardware and
software of its own. This frees the
user from installing the hardware and
software to execute a new application

◦ IaaS stands for Infrastructure as a Service.
With the help of IAAS, the user can use IT
hardware and software just by paying the
basic price of it. The companies that use
IaaS are IBM, Google, and Amazon. With
the help of visualization, the host can
manage and create the infrastructure
resources at the cloud. For small start-ups
and firms, the IaaS has the major
advantage as it benefits them with the
infrastructure rather than spending a large
amount of money on hardware and
infrastructure. The reason for choosing IaaS
is that it is easier, faster, and cost-
efficient which reduces the burden of the
organizations.

Speed: Most cloud computing services are provided self service and on
demand, so even vast amounts of computing resources can be provisioned in
minutes, typically with just a few mouse clicks, giving businesses a lot of
flexibility and taking the pressure off capacity planning.
Performance: The biggest cloud computing services run on a worldwide
network of secure datacenters, which are regularly upgraded to the latest
generation of fast and efficient computing hardware.
Productivity: Cloud computing removes the need for many of these tasks, so
IT teams can spend time on achieving more important business goals. Cloud
computing removes the need for many of these tasks.
Cost: Cloud computing eliminates the capital expense of buying hardware and
software and setting up and running on-site datacenters—the racks of
servers, the round-the-clock electricity for power and cooling, the IT experts
for managing the infrastructure. It adds up fast.

Security: Many cloud providers offer a broad set of policies,
technologies and controls that strengthen your security posture
overall, helping protect your data, apps and infrastructure from
potential threats.
Global scale: The benefits of cloud computing services include the
ability to scale elastically. In cloud speak, that means delivering the
right amount of IT resources—for example, more or less computing
power, storage, bandwidth—right when it is needed and from the
right geographic location.
Reliability: Cloud computing makes data backup, disaster recovery and
business continuity easier and less expensive because data can be
mirrored at multiple redundant sites on the cloud provider’s network.

Cloud security is a set of control-based
safeguards and technology protection
designed to protect resources stored
online from leakage, theft, or data loss.
DIFFERENT TYPES OF SECURITIES
PROVIDED BY CLOUD COMPUTING:
•Data center security
•Access control
•Threat prevention
•Threat detection
•Threat mitigation
•Redundancy
•Legal compliance
•Cloud security policy

Cloud service providers use a set of different
combinations to protect the data.
1. Firewalls protect the perimeter of your network
security
2. Disaster recovery is key to security since it helps
you recover data that are lost or stolen.
3. Threat intelligence spots security threats and
ranks them in order of importance. This feature
helps you protect mission-critical assets from
threats.
4. Data masking encrypts identifiable information,
such as names. This maintains data integrity by
keeping important information private.

The various applications of cloud
computing are:
1. Storing files online.
2.Recover data .
3.File converters.
4.Anti-virus applications.
5.Ecommerce applications.
6.Backup and recovery.
7.Video editing and streaming.
