INTRODUCTION
Cloud computing is the platform for computing the services, it manages the storage,
database and other services. It is the availability of the system resources; it is the server network
which is connected to the internet (Liu and et.al 2018). Main functionality of this platform to
share data, resources which involves the both physical and virtual server. Following report will
cover the detailed description of the cloud computing along with its utilities and tools. It will also
covers its various types and services and security of the cloud, also discuss the AWS and
Microsoft Azure cloud.
MAIN BODY
Understanding of cloud computing and its type
An on demand delivery platform of the IT resources over the network connectivity. It is
very convenient approach instead of maintaining, buying the server, user can easily access to this
technology services. Organisation of every size uses the CC as for the data backups, disaster
recovery, with this they can easily proceed to innovate faster, it also helps in testing the new
experiences for differentiation the consumer experience. Its types are as follows:
Public cloud: It is referring as the computing services which is mainly provided by the third
party over the public network connectivity. It is available for all the users who wants to utilise it
or buys it (Papadopoulos and et.al 2019). They can be free or can be sold on demand, which
allows the consumer to pay for only CPU cycles and for the bandwidth which they generally
consume. It is convenient option for the businesses, as they do not need to invest on maintenance
of hardware and application because the cloud service giver can maintain all the functionalities
by their own.

Private cloud: It is the cloud environment where the hardware, infrastructure is all accessible by
the single customer. It associates with many benefits as elasticity and scalability it also provides
the easy and accessible services with extra control and security. Most of the organisation uses
private cloud because of its simple mechanism and to completely meet the regulatory
compliances. It is a single tenant infrastructure which means that all resources are accessible to
one individual termed as the isolated access (Lv and Xiu, 2019). They are mainly hosted on
premises in the data centre of consumer.
Figure 2Private cloud
Hybrid cloud: It is the cloud where the application runs on a combo of various environments.
Approaches of the hybrid cloud are widespread because now a days there is no one who
completely depends on the public cloud platform. It linked both public and private cloud in a
5

manner as to sharing the data and resources between the platforms. Its main benefits is as it
cooperates with the remote working as well as improve the security.
Figure 3 Hybrid cloud
Multi cloud: A cloud computing model where the organisation uses the multiple clouds which
can be more than two private and public clouds. It is used by the organisation who do not want to
rely on the single cloud thus they utilise the various resources from the different service
providers in order to get the advantage from every unique services.

Architecture of cloud computing
Architecture for the CC associated with service oriented as well as with event driven
architecture. It is mainly splits into the two categories which are front end and back end.
Front end: This part is mainly utilised by the client which involves the interfaces from the client
side and the required application for the CC platforms. In which the front end includes the web
servers which are google chrome, Firefox (Stergiou and et.al 2018).
Back end: Back end is usually managed by the service providers, they manage all the resources.
It covers the good range of data as storage, virtual machines.
Essential components for CC architectures are as follows:
Client infrastructure: It is the front end element which helps in providing the GUI (graphical
user interface) for the effective interaction with the cloud platform.
Application: As the application are the software or any resources which is required by the client
for accessing.
Service: Cloud service usually manage what kind of the services are required by the client, thus
if user send the request for specific service then it provide with the services.

Figure 5 CC architecture
Cloud computing services
Various services are provided by the CC platform as software as a service(SaaS) which are
mainly web applications, platform as a service (PaaS) which gives the shared platform and
infrastructure as a service (IaaS).
SAAS: It is the services which delivers the applications of the software by using the network
connectivity. Instead of installing or managing the software one can easily access the services via
internet to free from any complex handling of the software and hardware components. It easily
enables the user to utilise the cloud based application by simply accessing the internet (Gao, Wan
and Shen, 2020). SaaS often termed as the wen based application it runs on the provider server
of SaaS. Its main advantage as it is cost efficient as no upfront price for hardware is required it
also provides the effective data security. Its architecture defines as the approach for software
delivery where the vendor can easily hosts the application remotely for the firm before physically
handling it to corporation. Its main examples are google apps, drop box, slack etc.

Figure 6 SAAS
PAAS: In this service third party provides the tools for hardware and software to the end users
over internet connectivity. These tools are required for the development of the applications. As
the provider of the PaaS mainly hosts the services own their infrastructure. It gives the better and
efficient computing platform which mainly consist of the operating system, coding language and
databases (Yoo and Kim, 2018). Example for the PaaS are AWS, windows azure, heroku etc. Its
main advantage as it is time saver as well as cost effective it also offers the mobility and
availability.

Figure 7 PAAS
IAAS: Infrastructure as a service provides the better access to the fundamental computing
services such as physical and the virtual servers over the network connectivity. It is one of the
most popular cloud computing services which offers the essential compute on demand. Its
benefits are to enhance the internet security which means that the IaaS service providers required
to heavily invest on the technologies, it also provides the future proof as to easy access the
hardware components and operating system.

Utility of CC
Agility: Cloud platform provides the better access to the various technologies in order to make
innovation. With this organisation can easily spin up their resources which is required for
computing, securing and databases. As the main use of CC is for the better and convenient
services, but its other goals are to give agility to organisation as to implement the new ideas for
their products and services.
Cost saving: As moving to the cloud platform provides the major cost benefit as it helps in
reducing the maintenance cost for the systems. As by investing on the other physical components
businesses can proceed to use the cloud services. With these businesses do not need to pay for
the expert staff and also energy consumption is also reduced and there is no delay in accessing
the services (Noor and et.al 2018). Cloud computing mainly operates on the web based platform
thus user do not require to keep all the bulky files on their system.
Scalability: cloud platform helps in rapidly increasing or decreasing the power size for the IT
solution. Scalability is the major hallmark for the cloud and the major driver for creating brand
11

popularity of the business. With this organisations can easily scale up their business , as it offers
the greater flexibility to make changes, as instead of buying an expensive upgrades, cloud
platform can done all this by its own.
Reliability: Reliability in the cloud can be measured of the probability where the cloud provides
the services which is designed for. It implies that the services are available at the cloud platform
and easily accessible to the client whenever they made request. Thus cloud computing provides
the reliable security and data storage options. Cloud services provides the better in dependability,
as with the right cloud security monitor, clients can easily access the data and application without
concerning with their physical location or what devices they are operating with.
Cloud security
Generally, the security concern is the major criteria which every organisation consider to
prevent their data from being out or from misuse. There are some cloud security practices which
involves the several points are as follows:
Data encryption: Data is completely encrypted while in transit and in use. It is required for the
clients to manage the control over the security keys and in hardware security. It is the best
approach for keeping the data saves while being transferred or collected in a cloud platform.
Shared authority for security: Usually the cloud service provider manages the security for the
cloud infrastructure and the consumer is responsible for the protecting their data in the cloud
system (Kamal and et.al 2020). But in such it is also important to clearly design the data
ownership among the private as well as in public third access.
Collaborative management: Effective communication between the IT teams, operational and
security teams will make sure the effortless cloud integration which are protected and
sustainable.
Tools for cloud computing
AWS
Amazon web service is the comprehensive cloud platform which is provided by the
Amazon that involves the different cloud computing services as IaaS, PaaS and SaaS. This
platform service offers the tools for the organisation as compute power, storage of the database.
It is one of the first organisation to first launch the pay as you go which helps in providing the

throughput to the users whenever it required. Any size of the organisation are using AWS for
experimenting, innovating and to become more agile.
Working of AWS:
Services of the AWS comes in a different form as from the infrastructural technologies
like computing and storing to the enhanced technologies such as artificial intelligence, internet of
things and other new technologies. it manages all underlying resources, it is also responsible for
the security measures for the entire stack, so the user can easily use it what they required.
Application of the AWS:
Backups and warehousing: One of the convenient use of the AWS as it provides the range of
options for storage and it can be easily accessible to the client (Izrailevsky and Bell, 2018).
Websites: By using this AWS platform companies can easily host or develop their websites on
AWS cloud platform, like other web services.

Azure is the cloud computing service platform which enables the user to easily manage or
access the cloud services that are mainly provided by the Microsoft. Thus these services covers
the resources which are data storage and transformation. It is the great collection of the servers
which mainly runs the complex part of the distributed process (Liu, Buyya and Nadjaran Toosi,
2018). Main benefits of the Microsoft azure is it provides the better and fast services, also
provides the flexibility and disaster recovery. As by using this platform organisation can easily
develop their website and they can easily test it by using its services.
