Initial Webserver Trial
The Cloud Computing Concepts
Concept Development of AWS
 Provides infrastructure services that includes computing power, networking, databases and storage options
 Facilitates a platform for every single use case (Oberhauser, 2014)
 Deep embedded features that help in the growth of business purpose
 Recognizable security features within the cloud platform
 Ensuring deep visibility into governance and compliance

Initial Webserver Trial
The Cloud Computing offered features by AWS:
 The AWS Cloud environment would support the IaaS instance for serving the webservers of DTGOV
 The AWS community would offer flexibility to build and support the application services (Usmonov et al., 2017)
 The AWS community would also provide mobile based solutions, website support, backup of business data and recovery feature
 The AWS cloud would offer analytics, database, application, global compute, storage and deployment services

Initial Webserver Trial
The business features offered by AWS:
 Offer high scalable services for business varying in sizes
 Commitment free and cost-effective services
 Reliable services and reliable connections (Sarabi et al., 2015)
 Customizable and flexible services

Initial Webserver Trial
Types of Cloud Architectures useful for DTGOV:
 Load Balancing
 Amazon Cloud-Front
 Elastic Load Balancer (Villamizar et al., 2016)
 Security Management
 Amazon RDS
(Fig 2: Representation of AWS Architecture)

Initial Webserver Trial
The migration of present DTGOV infrastructure to AWS cloud would incur the following steps:
 Future business planning and preparation for migration
 Discovery of Portfolio and planning
 Designing of planning strategy (García-Galán et al., 2016)
 Migration and Validation of application
 Operation after deployment

Office 365
The benefits of moving to Office 365 for the users of DTGOV are:
 Scalability of business services
 Work from anywhere
 Easy collaborative services (Lacity & Reynolds, 2014)
 Real-time updates and reduces spend capital
 Elimination of hardware and reduction of energy costs
(Fig 4: Video Calling services on Office 365)

Office 365
The other benefits of moving to Office 365 for the users of DTGOV are:
 Highly secure services
 Advanced security features (van Angeren, Jansen & Brinkkemper, 2014)
 Enhanced capabilities for storing emails
 More user connectivity
(Fig 5: Unlimited user connectivity on Office 365)

Office 365
The issues of moving to Office 365 for the users of DTGOV are:
 Difficulty in migrating to the cloud platform
 Office 365 is not fully web based platform
 Complications in receiving support
 Bandwidth related complications
 Problems with overlapping of application

Implementation of a Cloud Approach
The implications of a cloud based approach from implementing the Office 365 suite is:
 Continuity of Business Operations
 Efficiency in collaboration (Rittinghouse & Ransome, 2016)
 Flexibility within the practices of work
 Access towards automatic updates
 Scalable services

Differences between IaaS, PaaS and SaaS
The differences between IaaS, PaaS and SaaS are:
IaaS – They provide automated deployment of computing, storage and different other kind of networking services. A virtual
data center can be created and equipped with resource capabilities.
PaaS – This cloud service operates at lower level in comparison to SaaS. They also provide a platform that could be created
and launched (Kavis, 2014).
SaaS – They provide services at greatest level of abstraction. The cloud services enables users to connect and make use of
cloud based applications.

Examples of IaaS, PaaS and SaaS cloud-based Services
Type of Platform Common Examples
SaaS Dropbox, Google based applications, Salesforce, Cisco WebEx, GoToMeeting and
Concur
PaaS AWS Elastic Beanstalk, Heroku, Force.com, Windows Azure, OpenShift, Apache
Stratos and Google App Engine
IaaS Cisco Metapod, Google Compute Engine (GCE), DigitalOcean, Amazon Web Services
(AWS), Rackspace and Linode

Recommendation of a Cloud Service Model
Based on consideration over the three cloud service model, the IaaS is considered as the most preferable model. The
inclusion of IaaS services within the SharePoint service is important because:
 The different resources are distributed as a form of service
 Offers expanding and scaling of service (Sether, 2016)
 Supports multiple users on a single hardware piece, anytime and anywhere
 Offers service even in server downtime
 Pay only for services that are needed
(Fig 9: The business offerings of IaaS services)
(Source: Sether, 2016)

Recommendation for the use of IaaS in SharePoint Service
The use of IaaS model would be appropriate for the SharePoint service because:
 Provides backup and disaster recovery mechanisms
 Hybrid Deployment, Provides Internet facing portal deployment and deployment on SharePoint Intranet (Toroman, 2018)
(Fig 10: The IaaS services in SharePoint)
(Source: Toroman, 2018)

Problems with IaaS Cloud Service Model
The problems that are mostly been faced within the IaaS model are:
 Data security and privacy
 Compliance with legal and regulatory
 Responsiveness and control (Ahmed & Hossain, 2014)
 Lack of leading practice experience and benchmarking
 Lack of interoperability
 Resistance from IT personnel based in datacentre
 Ambiguity based on tracking and communicating
 Threat over reliability on a single provider of IT service
(Fig 11: The cloud challenges of IaaS services)
(Source: Ahmed & Hossain, 2014)

Recommendation for DTGOV to implement IaaS
The recommendation for DTGOV to implement IaaS within their business model are:
 Effective security framework should be implemented. This includes, audit and compliance, application level security,
data backup and recovery facilities and legal implications
 The firm should estimate the ROI with the implementation of IaaS services
 The cloud vendors should create different effective strategies based on value proposition
 Case studies of IaaS cloud adoption by consumers should be provided to enterprises
