Cloud Computing: DTGOV Web Server Migration and Architecture

This assignment report examines DTGOV's migration of web servers to an IaaS instance in the AWS cloud environment. It explores how the web servers will function, the impact on users, and the benefits of this migration. The report details the types of cloud architectures suitable for DTGOV, including discussions on IaaS, PaaS, and SaaS models. It recommends the SaaS model for DTGOV, emphasizing its advantages in terms of cost reduction, flexibility, and ease of management, particularly for SharePoint services. Furthermore, the report outlines potential problems DTGOV might encounter with the SaaS model, such as security concerns and configuration management, and provides recommendations on how to address these issues to ensure a successful cloud implementation. The report concludes by summarizing the key aspects of cloud computing and its application to DTGOV's web services.

INTRODUCTION
 Cloud computing is a basically terms that involved delivering the
hosted services over the internet. It is on the demand of
availability of computer system resources especially computing
power and data storage without direct active the management
process by users. It is generally used to describe the information
centres that available to many user through internet services.

DISCUSS THAT DTGOV WEB SERVER WORK IN IAAS INSTANCES IN THE
AWS CLOUD
ENVIRONMENT AND HOW IT WILL AFFECT THE USERS OF WEB
SERVICES.
 Amazon web services is started to offer IT services in market in the
form of web services which is also known as cloud computing.
 AWS is highly reliable, scalable and less expensive that's why, DTGOV
uses in their infrastructure platform to provide the services in different
countries
 The organization is mainly used the internet based computing services
which operates large number of remote servers and allows to centralized
the data. An AWS customer can spin up the virtual machine and also
replicate the data in different availability zone to achieve highly reliable
infrastructure that can resistant to failure of individual server.

CLOUD COMPUTING

DESCRIBE THE TYPE OF CLOUD ARCHITECTURE THAT
USEFUL FOR DTGOV USE AS A PART OF WEB SERVER
INFRASTRUCTURE IN CLOUD.
 Cloud Architecture is mainly referred to the different component
in terms of software capabilities, databases and application etc.
 It is defined the appropriate component as well as the relationship
between them.
 Cloud computing architecture is consists of components and
resources which delivered by the server side application through
digital network such as service conceptualizer, resource allocator,
cloud provider and service request controller or examiner etc.

DESCRIBE THE ISSUES AND BENEFITS OF DTGOV CONSUMER,
AND THEIR USERS TO ACHIEVE FROM THE OFFICE 365 AS
THEIR OFFICE AUTOMATION SUITE
 DTGOV operates the decentralization of Ministry that operates IT
operations to the public company. It has an autonomous
management structure with in the significant of flexibility to the
governs that evolves its Information technology enterprise.

BENEFITS
 It has ability to complete all the important task through access of
automation suite and office 365 because it easily solves the
problems in proper manner.
 It is reliable and flexible to share the information through Cloud
automation suite.
 It improves the client retention rates.

ISSUES
 Data has been lost due to errors
 It has generated a management issue in the system.
 It also increases the rep accountability.

DESCRIBE HOW A CLOUD-BASED APPROACH WILL DIFFER
FROM PROVIDING THIS SUITE FROM AN ON-PREMISE DATA
CENTRE.
 Cloud based approach is an advancement of technology in terms
of data storage that help for DTGOV to provide the best services
to the customers.
 Cloud based is much better than the other automation suite
because it is more flexible in terms of security and viability.
 Its time to consider the privacy when they provide the data
services. In terms of performance, it has measured the cloud
provider and their availability, making a plan to response towards
the interruptions.

DIFFERENTIATE BETWEEN THE IAAS, IAAS AND SAAS
MODELS
PaaS
 Pas operates at the lower level of abstraction as compare to SaaS.
 Paas standards for platform as a service.
 This type of model is delivering tools which necessary for the development of application
over the internet.
IaaS
 It is the agile cloud computing model which enables the automated deployment.
 Iaas stands for infrastructure as a service.
 This type of service model in the cloud computing which provide the virtualized
computing resources over internet.

CONT.
SaaS
 Saas is the most common type of cloud services with the greatest
level of abstraction.
 Saas stands for software as a service.
 This model is mainly hosts the software which makes them
available for the clients.

RECOMMEND THE MODEL THAT CONSIDER MOST
APPROPRIATE FOR THIS SERVICE AND DISCUSS HOW MODEL
IS THE MOST APPROPRIATE FOR THE SHAREPOINT SERVICE.
 It has recommended to DTGOV to use the SaaS (Software
as service) because it provides the facility to save time and
also reduce the cost. In this way, it helps to increase the
profitability and flexibility in terms of usefulness.
 Instead of share-point services, it adopts the high quality of
services to transfer data from one place to another. It is
remotely application which hosting or delivering, making
the most appropriate advantages.

THE MOST LIKELY PROBLEMS THAT DTGOV WILL
ENCOUNTER WITH THE MODEL THAT YOU RECOMMEND
 DTGOV is mostly adopting an ineffective strategy and other
problems that encountered by the organisation. It is required
for business to migrate with web server and AWS as a SaaS.
 SaaS Model helps for DTGOV to manage and build the data
without having the extra needs of hardware or setup costs
because it only based on the cloud service provider. It supply
computing power to easily run application in proper manner.
In this way, it has recommended implementing SaaS model for
accessing from any location by using internet connections.

HOW WOULD YOU ADVISE DTGOV TO DEAL WITH
THESE ISSUES
As per recommendation, it has need to determine the issues and
problem that arises in AWS cloud environment. There are
different type of issues generated where SaaS deals with it.
 Security concern
 Deploying at scale
 Configuration management
 Server-less
 Cost management

CONCLUSION
 As per discussion, it concluded that Cloud computing is a
type of delivering services such as storage, databases,
software, analytics and networking etc. It is usually used to
describe the information centres that available to many user
through internet services. It summarised that the DTGOV
webserver in the Iaas instances of AWS cloud environment
and they affect the web services
