Detailed Report: DTGOV Webserver Migration Strategy and Architecture

This report details DTGOV's plan to migrate webservers to an IaaS instance in AWS. The initial webserver trial explores the use of a cloud computing model with virtual hardware provided by AWS, focusing on increased scalability, availability, and effectiveness for users. The report recommends IaaS and SaaS as useful cloud architectures, specifically highlighting a hybrid cloud deployment model. It then examines the migration to Office 365 Suite, emphasizing productivity boosts and potential user adjustments. A comparison between cloud-based and on-premise data centers is provided, stressing the advantages of cloud-based approaches, such as reduced downtime and automated data backup. The deployment of Microsoft Share Point 2010 to the cloud is discussed, with SaaS recommended as the most appropriate model due to software access and remote flexibility. The report also addresses potential problems with the SaaS model, such as data confidentiality and limited user access, offering recommendations like data encryption and clear contracts to mitigate these issues. The conclusion summarizes the initial webserver trial assessment, the Office 365 migration outcomes, and the identified model for Microsoft Share Point 2010 deployment.

WEB SERVER
MIGRATION
DTGOV

INTRODUCTION:
• Initial trial of Webserver
• Migration to Office 365 Suite
• Deployment of Microsoft Share Point 2010 to Cloud

INITIAL WEB SERVER TRIAL:
• Cloud Computing Model is used.
• Virtual Hardware will be provided by AWS.
• Migration will affect the users in positive way.
• Users will be benefitted due to increased scalability, availability
and effectiveness.

USEFUL CLOUD ARCHITECTURE
FOR DTGOV:
• Useful cloud architectures for the DTGOV are IaaS and SaaS.
• Hybrid Cloud Deployment model (Manvi & Shyam, 2014) is used for replacing current DTGOV
infrastructure.

MIGRATION TO OFFICE 365 SUITE:
• Office 365 Suite will provide flexible working environment to the customers.
• Productivity will be boosted.
• Customers can be uncomfortable with new office suites.

DIFFERENCE BETWEEN CLOUD BASED
APPROACH AND ON PREMISE DATA
CENTRE:
• Downtime risk is nearly zero in cloud based approach (Sadiku, Musa & Momoh,
2014).
• Capacity can be easily upgraded if required.
• Automatic data backup and recovery will be achieved (Copeland et al., 2015).

DEPLOYMENT OF MICROSOFT SHARE POINT 2010
TO CLOUD:
• PaaS or SaaS models has been considered for deploying Microsoft Share Point (Fox, Patterson &
Joseph, 2014).
• IaaS provides infrastructure related service.
• PaaS provides platform service model.
• SaaS provides application service model installed within the server (Glazunova et al., 2017).

RECOMMENDED MODEL FOR SHAREPOINT
SERVICE:
• SaaS is recommended as most appropriate model (Kavis, 2014).
• Application software can be accessed through SaaS (Puthal et al., 2015).
• Software licencing is not required in SaaS.
• Provides remote flexibility to the users.

PROBLEMS WITH THE RECOMMENDED
MODEL:
• Microsoft Share Point 2010 can not be controlled at its full potential.
• Data confidentiality is not ensured in the SaaS model.
• User access can be limited within SaaS model.

RECOMMENDATION FOR DEALING WITH
THE ISSUES:
• Data encryption can be used to deal with data confidentially issue.
• Clear contract can be done which provides full accessibility of Microsoft Share Point.
• Better Enterprise Infrastructure that provides full access of Microsoft Share Point to the users.

CONCLUSION:
• Initial webserver trial is done and outcomes has been assessed.
• Office 365 migrated to the cloud and benefits and issues regarding it identified.
• Microsoft Share Point 2010 deployed to the cloud and appropriate model for the software has been identified.
