Webserver Migration Plan for DTGOV

This presentation provides a detailed plan for migrating the webserver of DTGOV, a public organization, to different topologies in three data centers. It covers the trial phase, cloud architecture, and the shift to Office 365. The benefits and issues of the migration are discussed, along with a recommended model for Microsoft SharePoint 2010. The presentation aims to help users understand the migration plan and make informed decisions.

WEBSERVER
MIGRATION PLAN
(DTGOV)
CLOUD COMPUTING

UNDERSTANDING DTGOV
• DTGOV is a public organization conducted by the social
security ministry.
• The organization provides IT operations to various
users.
• DTGOV targets to migrate to different topologies, to
the three data centres.
• Proper assessment of the migration plan is essential,
due to long time duration.

MIGRATION PLAN
• Webserver trail initialization.
• Deployment of Microsoft SharePoint 2010
to the Cloud (as Office Automation Suite).
• Migration to Office 365 suite.

1. 1) WEBSERVER TRIAL PHASE
• Implementation of cloud model to initiate
proper utilization.
• Introduction of virtual hardware for proper
allocation of webserver.
• Initializing the usage in AWS.
• AWS’s benefit for greater security and low-
cost implementation plan, to the respective
organization.

AWS
• Storage of data and its safety is
maintained in AWS cloud platform,
without any limitation to the data size.
• Increased effectiveness, availability and
scalability.

1.2) POSSIBLE CLOUD
ARCHITECTURE FOR
WEBSERVER MIGRATION
IaaS on Hybrid Cloud (using Burst In and Burst
Out technique):
The hybrid architecture of Cloud Bursting
allows organizations to increase capacities as
required.
Enhancement of cost-effectiveness and
performance consistency.
Self-service functionality, on-demand scale,
flexibility, fault-tolerance and automation
supporting human errors, lead to cost savings.

2) SHIFT TO OFFICE 365
• Office 365 can record, stored and back up
massive amount of user data over cloud.
• Customizable office suites.
• Portability of usage from any device.
• Better flexibility, services, sharing,
recovery and other features.

2.1) BENEFITS OF MIGRATION
TO OFFICE 365
• Flexibility of access
• Improvement in team collaboration
• Threat Intelligence
• Regular and automatic updates
• Mobile device management
• Advancement in security
• Flexibility in plans

2.1) ISSUES OF MIGRATION TO
OFFICE 365
• Absence of Internet connection can affect the
continuation of services.
• Issues to compatibility may occur during on-
premises device and system usage.
• Absence of data ownership.

2.1) CONTRAST OF CLOUD-
BASED APPROACH TO ON-
PREMISE DATA CENTRE
• Features of providing increased storage
space (Kumarasamy et al., 2016).
• Data backup and recovery methods are
easy and automatic.
• Downtime risk is close to ‘Null’ in cloud
based approach (Rittinghouse &
Ransome, 2016).

3) INTRODUCING MICROSOFT
SHAREPOINT 2010
• An intuitive document management and
collaboration platform.
• Management of documents, archives,
reports and any content, to any business
industry.
• Compliance to web standards like WCAG
2.0 AA, XHTML and others.

3.1) RECOMMENDED MODEL FOR
MICROSOFT SHAREPOINT 2010
EVALUATION
• SaaS is the most recommendable option, among other
migrating medias of IaaS, PaaS and SaaS.
• SaaS provides non-customizable cloud hosted software
services. They relate to infrastructure-based services (Kavis,
2014).
• PaaS provides customizable cloud hosting services over on-
premises application. They relate to platform-based service
models (Alam,Pandey & Rautaray,2015).
• IaaS provides a platform to host on-premises cloud services
(installed within a server) (Sadiku, Musa & Momoh, 2014).

3.1) BENEFITS TO THE
RECOMMENDED MODEL
• Increased Accessibility
• No need of software licensing.
• Increased flexibility with enhanced services.
• Supports customization, and saves extra-
costs.

3.2) ISSUES TO THE
RECOMMENDED MODEL
• Stable and continuous internet connection.
• Inadequate utilization of Microsoft
SharePoint 2010.
• Issues to data confidentiality.
• Significant restrictions (like, User access) of
SaaS model (Motavaselalhagh, Esfahani &
Arabnia,2015).

3.2) RECOMMENDATION FOR
MITIGATING ISSUES
• Implementation of Data Encryption methods, will
support handling and resolve the confidentiality
issues.
• Enhancement in Enterprise infrastructure would
initiate and maintain restrictions (Microsoft
SharePoint 2010).
• Proper accessibility can be maintained by clear
and concise contract (SLA) allocation between the
organization (end-user) and the service providers.
