Definition of Cloud Computing
According to Hashem et al. (2015), cloud computing is basically a type of outsourcing
with computer programs. With the use of cloud computing, the applications and the software are
accessed from wherever the user wants that is usually hosted by some outside party. The
computer programs are outsourced by implementing cloud computing. While using the cloud
computing, the user do not have to worry about the storage systems, the power of the system and
simply get the final result. The computing services are delivered by the technique of cloud
computing. The services that are provided are storage, software, databases, servers, and
networking over Internet. The companies who offers computing services are known as cloud
providers and charge a particular amount for the service they are providing, which is mainly
based on usage.
Types of cloud services
There are three types of cloud services. The types of cloud services are:
IaaS (Infrastructure as a Service): This is known as the best practice of all the services
of cloud computing. The IT infrastructure can be rent with the IaaS service of cloud
(Abdelwahab et al. 2014). The infrastructures that are provided generally has the servers and the
virtual machines, operating systems, networks, and storage from cloud provider on the basis of
the pay.
PaaS (Platform as a Service): This service is provided with the supply of environment
that is on demand so that all the processes including development, test, delivering the project,

and also managing the applications of software. PaaS makes the task easier for all the developers
so that there is worrying about managing and setting of the infrastructure.
SaaS (Software as a Service): SaaS is generally a method that is used to deliver the
application of software over internet, deliver of the application is on demand based on
subscription (Zhang et al. 2014).With the help of SaaS, the providers of cloud manages and hosts
the application software, and also underlines the infrastructure, and handle the maintenance such
as security patching, software upgrades and many more. The application is connected by user
over internet and via web browser on tablet, phone, and on PC.
Types of Cloud Deployments
There are basically three types of cloud deployments: public cloud deployment, private
cloud, and hybrid cloud
Public Cloud Deployment: The public cloud is generally owned and are operated by a
cloud provider who operates as a third party. The service provider helps to deliver the resources
like storage as well as servers via the Internet (Truong and Dustdar 2015). An example of cloud
provider is Microsoft Azure. With the help of public cloud, cloud provider manages the software,
hardware and all the supporting infrastructures.
Private Cloud Deployment: The private cloud that is included in cloud computing
resources are mainly used by organization or businesses. The private cloud is generally located
on the datacenter of the company (Chang, Kuo and Ramachandran 2016). Some of the
companies work on private cloud and take services from other service provider. The private
cloud is considered as one of the services that provides the infrastructure of the private network.

Hybrid Cloud Deployment: The hybrid cloud is a combination of both the private cloud
and the private cloud that are tied together with the help of technology so that they can allow
other applications and data to share in between them. With allowing of applications and data to
transmit freely in between the public and the private cloud, the hybrid system serves as a flexible
system.
Need of Cloud Computing
All the online services that are done such as sending an email, editing a document,
watching movies r televisions, playing games, listening music or some other tasks, are done with
the help of cloud computing. Cloud computing always works behind the screen while dealing
with all the activities that takes place (Fernández et al. 2014). The services that are provided by
cloud computing are not very much old but most of the organizations from small to large global
corporations, non-profit organizations, government agencies, uses the technology of cloud
computing. The advantages of cloud computing are:
1) New applications and services can be created;
2) Store the data, recover, and backup of data can be obtained;
3) Cloud computing hosts blogs and websites;
4) They help to deliver the software as on demand;
5) They also helps to analyze the data patterns so that predictions can be made.
Advantages of Cloud Computing
The advantages of cloud computing is as follows:

1) Lessen the cost: The capital expenses that are included in buying, implementing, and
marinating software and hardware are much more and cloud computing helps to eliminate those
extra expenses (Chen et al. 2015). The cloud computing helps to rack server, helps to save the
electricity, and faster cooling of the system. It makes the system faster.
2) Increases the speed: The services that are provided by cloud computing is generally a
self service and when demanded, the resources of computing are provisioned within some time.
The speed of the works generally speeds up with flexibility and provides capacity planning.
3) Global Scale: The benefits that are provided by services of cloud computing mainly
includes the ability for measure the elasticity. The right quantity of resources in IT sector such as
computing the power, bandwidth, and storage are provided by cloud computing.
4) Productivity: Generally a lot of headache is included with the hardware setup and the
software patching that are included system. Those set up are also time consuming. The aim of
cloud computing helps to remove all the basis needs that are served by all the tasks, so that the
organizations or businesses can meet their goals.
5) Performance: The most important service that is provided by the cloud computing is to
keep the data secure and the datacenters are automatically upgraded from the older version to the
latest generation making the system faster and computer efficient. The network latency is
generally reduced by the services that are provided by cloud computing.
Disadvantages of Cloud computing
The disadvantages of Cloud computing are as follows:

6DIGITAL MARKETING TECHNOLOGY
1) Usability: The user using the services of cloud computing should use the system
carefully (Katyal and Mishra 2014). The user should carefully drag and drop all the documents to
move from one place to another place. Copying and pasting is not allowed in Cloud computing.
2) Bandwidth: Specific bandwidths are allowed by some particular services of cloud
storage. Additional charges are charged with the business uses the surpass badwidth that is
allotted to them.
3) Accessibility: The great disadvantage of cloud computing is that if the internet
connection is not provided, the user cannot access the data stored in cloud.
4) Data security: The security of data is the most vital part while dealing with data. The
privacy and the safety of the data that are stored should be maintained. There is also a possibility
that the data is not secured and there is a chance of insecurity of data.
