DTGOV MIGRATION STRATEGIES
• Describing a trial phase for webserver
• Migrating the server to office 365 suite
• Microsoft share point deployment into cloud based server
• Developing a virtual hardware with the use of AWS
• The major benefits that are obtained with implementation of
cloud
• The main benefits obtained by DTGOV by migrating to cloud

INITIAL WEBSERVER TRIAL
• In this stage the proper utilisation for cloud model is being implemented
• In order to have a proper webserver it is important to include a virtual hardware
• The virtual hardware used here is AWS
• Benefit of AWS is that it provides better security and can be implemented with low cost
• Ensures proper privacy towards the data centres

IMPORTANCE OF AWS
• AWS provides all necessary towards the business
• AWS offers secured storage and will ensure that DTGOV has stored all data efficiently
• In addition to this AWS offers virtual hardware for ensuring proper working of the cloud storage
• AWS ensure highest security and an efficient way of managing the data
• AWS also ensures that storage capabilities are increased

REASON BEHIND MIGRATING TO CLOUD
SERVER
• The main benefits obtained with migrating to cloud includes:
• Better scalability
• Ensures great mobility
• Proper control over document
• Better connectivity is provided
• Easy recovery from disaster

BENEFITS OFFERED
WITH CLOUD SERVER
• Once the migration is
completed it becomes easy to
access the assets
• Ensures proper deployment of
data, applications and digital
assets over cloud platform

TYPES OF CLOUD ARCHITECTURES
• There are basically three types of architecture provided by
cloud.
• This are IaaS , SaaS and PaaS.
• DTGOV aims at implementing cloud computing with the use of
SaaS and IaaS.
• IaaS provides a better virtualized computing resources
• SaaS offers better flexibility towards the cloud server
• DTGOV aims at deploying a hybrid cloud that will overcome the
flaws of present architecture
• The hybrid cloud model will ensure better scalability and
accessibility towards the users

OFFICE 365- MIGRATION AND CLOUD
DATA CENTRES
• Reason behind migrating to office 365 is that it offers
better flexibility
• Provides a better and flexible environment towards
the company and its customers.
• In addition to this the organization will also include
on premise data centre for ensuring better
accessibility
• Benefits offered with cloud data centres are easy
data recover, easy sharing, automaton and saves
huge amount of cost

SHAREPOINT
• The cloud architecture that is chosen for deploying Microsoft SharePoint in cloud is SaaS
• In addition to this IaaS is being used for providing infrastructure associated service
• Application model within the cloud is installed by SaaS.

IAAS, SAAS AND PAAS
• The major difference between IaaS , SaaS and PaaS are described below:
• SaaS: operates widely on functional environment provided
• This offers effective function for third part vendor
• PaaS: platform as a services
• This provides an effective platform for ensuring better facilities towards
the users.
• IaaS: infrastructure as a services
• Provides a virtualized computing resources
• Helps the business at time of expanding the business.

SELECTED MODEL FOR MICROSOFT
SHAREPOINT
• SaaS will provide better way of deploying the SharePoint
• Thus it is recommended too use SaaS architecture
• There is no need of software licensing in SaaS
• Eensures better flexibility towards the users
• Benefits offered with SaaS are: offers easy up gradation towards the system, easy customization is provided, saves huge
amount of cost

DRAWBACK OF SUGGESTED MODEL FOR
SHAREPOINT
• It becomes difficult to maintain the confidentiality of data stored within cloud
• SaaS limits the access provide towards the users
• SaaS is basically a hybrid IT infrastructure that leads to several challenges
• Time required to deploy is huge
STUDENT ID:
STUDENT NAME:

STRATEGY TO OVERCOME THE
CHALLENGES FACED WITH SAAS
• Data encryption within the cloud will ensure proper confidentiality towards the data
maintained
• Proper contract needs to be prepared so that user can have proper access on data
• Enhancing the infrastructure will ensure better benefits towards the users.
