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.
(Source: Dinh et al., 2013)

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.
(Source: Hashizume et al., 2013)

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.

Cloud Based Approach differ from
Office 365 Suite in DTGOV
The implementation of a cloud based approach is
quite different from the implementation of Office 365
suite in DTGOV.
The cloud based approach is being utilized for
mitigating the risks and complexities of the data
migration and hence removing the several concerns
like regulatory requirements, effective data
governance, application as well as infrastructure
security and many more (Carlin & Curran, 2013).

Cloud Based Approach with Office 365 Suite
When the IT department of DTGOV has properly addressed the various
risk factors, they can easily move on to the plan the best cloud migration
approach for meeting the organizational requirements and objectives.
The main approaches of cloud based approach with office 365 suite are
as follows:
 Lift and Shift.
 Refactor and Rearchitect.
 Shelve and Spend.
(Source: Carlin & Curran, 2013)

Difference or Implication of Cloud Based
Approach from Providing the Suite from an On
Premises Data Centre
The major implications of any cloud based approach
before deploying the office automation system of
Office 365 suite are as follows:
 It will be providing proper continuity of the business
operations (Hashizume et al., 2013).
 The departmental collaboration becomes extremely
efficient and effective.
 The flexibility in work practice is the next major
benefit.

Implications Contd..
The other implications are as follows:
 Provides significant access to the automatic updates
and upgrades.
 The services are both scalable and effective.
 Cost effectiveness is yet anther important
implication here (Carlin & Curran, 2013).

Differences between IaaS, PaaS and
SaaS
DTGOV is considering whether to utilize PaaS or SaaS for
providing few important services to the customers.
They have also deployed Microsoft SharePoint 2010 from
the data centre as the major documentation and
collaboration tool (Xiao, Song & Chen, 2013).
They have also moved the SharePoint 2010 instance to
the cloud for making it more available to more customers.
There are several differences between IaaS, PaaS and
SaaS.

Differences Contd.
 IaaS: This particular architecture model provides
automatic implementation of storage, computing and
even various types of networking services. It is
responsible for providing a virtual infrastructure.
 PaaS: This This particular architecture model operates at
the lowest level while compared to the other models. A
virtual platform is being provided here (Manvi & Shyam,
2014).
 SaaS: It is responsible for providing services at the highest
level of abstraction and thus services are made easier.

Recommended Model for DTGOV
The recommended and suggested model for DTGOV organization is
IaaS or infrastructure as a service.
It would be extremely appropriate for the SharePoint 2010 services.
The virtualized platforms are used like servers, networks, storage and
operating systems. The cloud servers are being provided to DTGOV
through API and the clients have entire control on the infrastructure.
(Source: Xiao, Song & Chen, 2013)

Problems with IaaS with their
Solutions
DTGOV might face some of the most significant issues
while implementing it to the business.
The major issues and their solutions are as follows:
 Insider Threats: This can be removed by antivirus
software (Rittinghouse & Ransome, 2016).
 Escaping Virtual Machines: Implementation of
SELinux can be effective for it.
