DTGOV: Analysis of Cloud Architectures and Office Automation Solutions

This report examines DTGOV's cloud migration strategy, focusing on migrating web servers to an IaaS instance within AWS. It details the benefits of AWS, various cloud architectures (single server, single site, load balancer, three-tier architectures), and the migration process. The report also explores DTGOV's implementation of Office 365 for office automation, highlighting its importance, benefits, and potential issues. It compares cloud-based approaches with Office 365, detailing the differences between IaaS, PaaS, and SaaS, and recommends IaaS for DTGOV's SharePoint 2010 services. The report concludes by addressing potential problems with IaaS and their solutions, along with a comprehensive list of references.

Selected DTGOV Webservers working in an
IaaS instance in AWS Cloud Environment
DTGOV wants to migrate few of their webservers to an
IaaS instance within AWS for testing their strategy.
They have understood that they require a complete
migration plan at first, however now they want to
determine the type of architecture that is needed for
supporting the web servers.
IaaS is the form of cloud computing, which provides
virtual computing resources on the Internet. It is a
main category for cloud services similar to SaaS and
PaaS (Hashem et al., 2015).

Affect of AWS Cloud Environment on
Users
The users of AWS cloud environment gets several features
after it is being used as a webserver and these are as
follows:
 Provides services of infrastructure of networking,
storage options, computing power as well as databases.
 The users of DTGOV even will be facilitating for all the
single use cases.
 Since the security is high, there would be a major
growth in business and compliance.

AWS Web Server for DTGOV
There are few important concepts of cloud computing that are
required to be considered while migrating to IaaS. One of the most
significant application of IaaS is AWS Cloud Environment
(Fernando, Loke & Rahayu, 2013).
AWS cloud platform provides some of the most important features
and characteristics and the major benefits are as follows:
 Extremely high security.
 Cost effective and hence affordable by all.

Benefits of AWS Contd..
The other advantages that DTGV might get from AWS
platform are as follows:
 Easy in utilization.
 Provides high speed as well as agility.
 No limit for capacity.
 Extremely reliable.

Types of Cloud Architectures Useful for DTGOV
There are some of the major and the most significant types of cloud
architectures that would be useful for DTGOV. They are as follows:
 Single Server.
 Single Site.
 Load Balancer.
 Non Redundant Three Tier Architectures.
 Redundant Three Tier Architectures.

Process of Migration of current
Infrastructure to AWS Cloud
The migration of the current infrastructure to AWS
cloud environment can be completed in few steps:
 Purpose to move to the cloud.
 Planning and assessment.
 Assessment of Compliance and Security.
 Assessment of technical and functions.
 Training of Staff.
 Selection of right partners.
 Maintenance after moving.

Office 365 as Office Automation
The staff of DTGOV want to provide all the customers
with a core ability of accessing office automation
system.
It is needed for better execution of business processes
and better management of information and data
(Rittinghouse & Ransome, 2016).
The office automation system would be helpful to
optimize as well as automate existing office
processes.

Importance of Office Automation
The office automation or Office 365 would be bringing
some of the major benefits in DTGOV for their
customers and staff.
There is a significant importance of this type of
automation. The emails, word processing as well as
spreadsheet capabilities would be easily and promptly
managed after involvement of Office 365.
They can even access files while working at a remote
site within the field.

Benefits from moving to Office 365
The major benefits that the users and customers would be getting from moving
to office 365 are as follows:
 The tasks would be completely faster.
 Helps in eliminating the requirement for excessive involvement of staff.
 It provides less storage for storing the data (Garg, Versteeg & Buyya, 2013).
 The several people could upgrade the data simultaneously regarding the
changes in schedule.
(Source: Dinh et al., 2013)

Issues faced while moving to Office
Automation
In spite of having major benefits, few issues could also
be faced while moving to Office automation.
 Extremely Expensive.
 Process of involving Office 365 can be quite lengthy.
 Adjustment to this office automation system is
extremely difficult.
 Lack of access control.

Cloud Based Approach for DTGOV
The cloud based approach refers to the type of
approach towards applications, resources and services
that are made available to the users on demand
through the Internet connection from the cloud
computing servers.
This type of approach is responsible for increasing the
overall capacity, enhancement of functionalities and
even adding the additional services on demand
without even having a potentially expensive
infrastructure costs.
