DTGOV Web Server: Cloud Computing, Migration and Architecture Report

This report examines the cloud computing strategy for DTGOV's web server, encompassing the initial trial using Amazon Web Services (AWS), the subsequent migration to Microsoft Office 365, and the deployment of Microsoft SharePoint. The report highlights the use of a hybrid cloud model with SaaS and IaaS architectures, emphasizing the benefits of AWS such as enhanced security, scalability, and functionality. The advantages of migrating to Office 365, including improved flexibility and data accessibility, are also discussed. The analysis further explores the architecture of SharePoint, recommending SaaS deployment for optimal efficiency while acknowledging potential drawbacks like slower speed and connection issues. The report concludes with recommendations for better encryption, infrastructure maintenance, and a step-wise development approach to ensure successful cloud implementation. References from relevant academic sources support the analysis.

DGTOV WEB SERVER

About the presentation
• First part : Initial trial of webserver
• Second part: Migration to Office 365 suite
• Third Part: Microsoft SharePoint deployment

Cloud computing

1. Initial trial webserver
• Includes deployment of cloud computing model
• Virtual hardware is provided by Amazon web server
• Architecture provided by AWS is a combination of three forms and hence is known as hybrid cloud
• Migration will ensure better profits towards the organization
• Better accessibility, scalability and effectiveness is observed

Amazon webserver

Cloud Architecture for DTGOV
• Cloud architecture used by DTGOV are SaaS and IaaS
• With the use of hybrid cloud model DTGOV will replace the existing issues
• Benefits offered with AWS includes better security and scalability
• AWS also ensures better functionality

Migration advantages
• Ensures better deployment of IT infrastructure
• The organization will be able to access all assets once deployment is done
• Services will be accessed by user at any point of time without any problem

2. Office 365
• This provides better flexibility
• Better profit will be obtained with the deployment of office 365 in system
• Provides a better access towards the data

On premise data centres
• Stores data that can be accessed by the users at any time
• This is a private data centre
• Data will be accessed by people associated with the organization
• Data centre ensures authenticate person are allowed to access the data

Advantages of cloud data centre
• Easy data recovery from disaster
• Easy access towards the data
• Ensures sharing of data effectively
• Better security is provided towards the organization

3. Microsoft Share point
• The cloud architecture used for deploying share point are IaaS and SaaS.
• However the recommended and most suitable one is SaaS
• SaaS ensures better efficiency towards the software
• There is no need of software license for SaaS
• Better flexibility is provided

SharePoint

Cloud architectures

SaaS architecture issues
• Slower speed as compared to other architecture
• Connection issue occurs
• Lacks to provide confidentiality
• Limited access is provided to customers

Recommendation
• Better encryption needs to be developed
• Enhances the way infrastructure is maintained
• Organization needs to focus on step wise development for better result
• Each step needs to be monitored effectively
