Report: DTGOV Webserver Migration to AWS Cloud and Architecture

This report details DTGOV's plan to migrate webservers to an IaaS instance in AWS. It begins with an initial webserver trial, explaining the move's impact on users and benefits like scalability and availability. The report then suggests appropriate cloud architectures, recommending IaaS and SaaS models, and discusses hosting the Office 365 suite in the cloud. It explores the differences between on-premise and cloud-based data centers, recommending SaaS for Microsoft SharePoint 2010 implementation and addressing potential issues like restrictions and data confidentiality. The report suggests solutions such as enhanced enterprise infrastructure and data encryption, and concludes by emphasizing successful deployment through issue analysis and mitigation strategies. References to relevant research are included, and the student's work is presented in a PowerPoint briefing format as requested by the assignment brief.

3 TRIAL OF WEBSERVER
 All the required virtual hardware would be provided by the
AWS.
 The model of cloud computing is utilised.
 The migration to the cloud environment would impact the users
in positive manner.

4 APPROPRIATE CLOUD ARCHITECTURE FOR THE
COMPANY  The cloud architecture that would be most useful for the
company is the IaaS and the SaaS.
 In order to replace the prevailing cloud infrastructure, the
company could utilise the hybrid cloud deployment model

5 HOSTING OFFICE 365 SUITE IN CLOUD
 The employees of the organisation could gain the increased
flexible working environment for working in the cloud.
 There would be significant increase in the productivity
 The major issue that could impact the company is the hesitation
of the employees of the organisation to adopt the modern
technology.

6 DISSIMILARITIES AMONG ON PREMISE AND
CLOUD BASED DATA CENTRE
 There is minimal downtime risk associated with the approach of cloud
storage.
 There is a facility of the increasing the storage space in the cloud as per
the requirement (Prabadevi & Jeyanthi, 2014)
 One more advantage that could be achieved by the organisation would
be features of the automatic backup and the automatic recovery.

7 MICROSOFT SHAREPOINT 2010
IMPLEMENTATION
 The model of the SaaS is recommended for Microsoft sharepoint
2010 implementation.
 IaaS could be utilised for the services that are connected to the
infrastructure
 Paas could be utilised for the service model of the platform
 The service model of the application could be implemented using
the SaaS
Student Number

Student name
8 SUGGESTED MODEL FOR THE MICROSOFT
SHAREPOINT IMPLEMENTATION
 Suggested model is the SaaS cloud that could be utilised for the deployment.
 Accessibility is increased using the SaaS cloud.
 There is no requirement of the software licencing in the SaaS
 The required flexibility is provided in the SaaS

9 PROBLEMS WITH THE SUGGESTED MODEL
 There might be the significant restriction in the SaaS model
(Behal & Kumar, 2014).
 There might the situation of inadequate utilisation of the
Microsoft Sharepoint 2010
 There is no assurance of the data confidentiality
Student Number

Student name
10 SUGGESTION FOR HANDLING ISSUES
 The enhanced Enterprise infrastructure could be utilised for the complete
access of the Microsoft Sharepoint service to users
 Data encryption could be utilised extensively for proper handling of the data
confidentiality issues
 Clear SLA could be done that would enable the complete access to the
Microsoft Sharepoint
