Analysis of Cloud Computing Solutions for DTGOV Webserver Migration

This report analyzes the cloud computing strategy for DTGOV, focusing on migrating web servers to an IaaS instance in AWS. It begins with an initial web server trial, explaining the impact on users and the benefits of the move. The report then explores cloud architectures, including front-end, back-end, and cloud-based delivery models, recommending Iaas services in AWS for cost-effective deployment. The report also assesses office automation using Office 365, outlining benefits and migration issues. Furthermore, it compares cloud models like Iaas, PaaS, and SaaS, recommending SaaS for easy management and scalability. The conclusion emphasizes the importance of effective web servers and recommends appropriate cloud models for DTGOV, offering insights into cloud-based services, and the differences between various cloud models to improve the firm's services.

CONCLUSIONS
Table of Contents

 Cloud computing is termed as on-demand availability of computer system
which is especially used in data storage, data retrieval and various
computing resources without the direct involvement of the user. It allows
the practice of hosting the servers remotely via internet in order to store,
manage and process the data on cloud rather than a local server or
personal computer. This study will be based on the cloud computing
technology of the GTGOV organization who is planning to migrate its web
servers to Iass instance in AWS. This report will provide various
architecture solutions to support the appropriate web services.
INTRODUCTION

Formulation of the Selected web server in DTGOV and effects of these web
services to users
AWS (Amazon web service) is a web service that provides the secure and
resizeable compute capacity in the cloud. It is mainly designed to make
web-scale computing easier for developers. The Amazon web service
interface allows the user to obtain and configure the capacity with
minimal friction (Dastjerdi And et.al., 2016). It also reduces the time
required to boot new server instances and also allow the users to quickly
scale the capacity according to the change in the computing
requirements.
INITIAL WEB-SERVER TRIAL

 This is mainly belongs to Infrastructure as a service which allows on
demand instances. DTGOV migration plan will be benefited to the
company and effects the users in various ways such as :
 It provides secured infrastructure to users and also helps in securing the
private information of the users.
 It may negatively affects the users as the attackers can easily gain the
access to control panel and demand money.
 AWS environment reduce the potential impact of a cyber attacks
Con..

 Cloud computing architecture refers to components and subcomponents
required for cloud computing (Garcia Lopez and et.al., 2015). These
typically consists of platforms such as front-end, back-end, cloud based
delivery and network such components are described below:
 Front end platform Consists of fat client, thin client and mobile devices.
Such clients interact with cloud data storage via application, browser or
virtual session.
Types of cloud architectures and replications of the
current web server used in GTGOV

Cont..
 Back-end platform Includes the server and storage of the database which
may consists of cloud based delivery. It allows the users to write service
side code and other services.
 Cloud based delivery and a network includes various models such as
Software as a service, Platform as a service, infrastructure as a service etc.
 GTGOV current web services need to be replaced with Iaas Services in
AWS environment because it provides cost effective and scalable
deployment of the apps (Quilachamin, Alonso and Ra-Tapia, 2018). it
provides the developers to create customised apps and advances easy
migration to hybrid model.

Determine the best way for office automation customers and Benefits along
with issues related to the migration of the web service towards Office 365
Office automation refers varied computer machinery and software which
is used to digitally create, collect store and manipulate the Office
information needed for accomplishing for basic tasks. Various benefits
involved in GTGOV related to the office automation are as follows:
It improves the productivity and optimise existing office procedure
It saves the time, money and human efforts.
OFFICE 365

 Issues related with the migration of Office automation suite 365 are as
follows:
 Increased operational cost
 Decreased diversity of hardware platforms.
 Customised requirements
Cont.

Difference between cloud based approach and on-
premise data centre
 On premises refers to private data centres that companies generally house
their own facilities and maintains the web services. It is used to run
private clouds which generally contains virtualised compute resources in
as a public clouds. On the other hand GTGOV wants to expand its
business operations so they need to develop the effective cloud based
services. So cloud computing highly encrypted data .
 It allows the capacity to easily scale up and down the web services. It
allows the used based prices to GTGOV. It also provides the automated
data backups and recovery.

Considerable web services for GTGOV
Saas is considerably the best solution for the problem of GTGOV as it can
be easily managed from the central location and hosted on the remote
server. Various situations in which Saas will be most beneficial for the
GTGOV are as follows:
 This can provide easy access for both web and mobile access.
 GTGOV will be beneficial in launching e-commerce with the help of such
model.
 It also reduces the time consumption on installing, managing and
upgrading the software
SHARE POINT

 Iaas: Infrastructure as a service allow GTGOV to buy compute
environment, storage disks, operating system etc from the cloud service
provider. It easily allows for the automated deployment of storage,
networking, server and processing power.
 Saas: In Software as a service, most of the services are generally managed
by service provider. It utilises the internet to deliver the applications to its
users which are generally maintained by third party vendor
 Paas: Platform as a service helps GTGOV in controlling the database and
which are provided as a managed services via service providers.It allows
the businesses to design and create applications in order to provide
proper platform for software creation.
