Cloud computing

INTRODUCTION
As more and more businesses and service providers are going online and digital, the proper management of the
web servers and data servers is turning out of the challenge. The proper selection of a web services and
online service provider is a major factor that is required to be managed and carrying out of operations in an
effective way. DTGOV is a public firm that works with different IT organisations within the country. It works
with the ministry of Social protection and govern the proper planning of services offered by the firm. Details
of the technical infrastructure of the web service provider and its operation environment is provided with
the goals to move on cloud based services offered by Amazon Web server (AWS). The business goals and
strategy, cloud architecture and use of Microsoft Office 365 with the share points have been discussed.

Initial Web server trial:

1 How DTGOV work in IaaS instance that will operated in IaaS platform of AWS
DTGOV will look after the proper planning of IaaS platform services in AWS by the means of Elastic Computing service or EC2. This
is a flexible approach that will help in tracking down the data that is been processed by the firm and provide suitable report
for the organisation.
 This will also provide the automated service of data handling measures of organisation. The moving of the server under IaaS
will help the selected enterprise to carry out their data management operations on the server in an effective way. It will
improve elasticity to handle large amount of data and ensures suitable resource allocation.
 The service users will be deeply benefited by this approach as it will provide them with real time information of the data that
is been tracked down and benefit them to keep a back up and report any sort of technical glitches and restriction faced by
the firm.
 Also, the cloud environment will improve the flexibility or ease of accessibility measures which will help in gaining the data or
information managed by DTGOV from anywhere and anytime. This will lead to development of an open source and fast
accessible data infrastructure.
 Other than this, the moving of these web server services in the IaaS platform of AWS will help in increasing the handling of
large quantity data.

2 Types of Cloud architectures and its usefulness of the Cloud structure that is been deployed.
There are basically 4 types of cloud architecture that will help in carrying out of the services and cloud related facilities. The basic
classification is:
 IaaS (Infrastructure as service) : It is basic service of cloud computing and forms the building block of cloud related services.
It includes the components like network lines and computers that will also look after the proper planning of the data storage
measures. It has the highest level of operational flexibility.
 PaaS (Platform as service) : It causes the user to reduce their dependency on the H/W and S/W based services which will
help in deploying the services that will help in proper planning of the services. This will improve their ability to carry out
resource procurement, software maintenance, processing capacity planning.
 SaaS (Software as service) : This cloud based services will provide a complete package of service that will help in improving
the quality of software and maintain the establishment of operations which will help in installing a web based model and
including the patch files within the system that will provide a hiogh quality services and setting up of the email based services
with clustered OS.
 RaaS (Recovery as Service) : This is a trial service which provides the facility to store and backing up the data and storing it
for the recovery of data loss due to disaster or other factors. This service can be used by DTGOV in future to process and
recover a wide variety of file of different extension.

Office 365

Benefits and issues faced by DTGOV customers and their users to moving on Office 365 automation suite
The Office 365 automation suite is one of the most interactive online cloud based service which will help an enterprise like
DTGOV and its users a facility to have a faster accessibility of the automated data that will include the usage of emails,
documents, spreadsheets and other online facilities. The major benefit and issues related to office automation suite is as
follows:
Advantages of Office 365 Automation:
 Flexibility of access: Office 365 Automation suite provides the facility of carrying out of the office document and accessibility
of the users emails and other files at anyplace, anytime, through online basis. This can increase the remote
accessibility of the users of DTGOV.
 Provides collaboration: Office 365 Automation suite provides the facility of creating the collaboration of various system.
Besides this, it will help in proper planning of the getting the real time and multi version combination of the documents on
different systems and accessing the files directly rather than as attachments as DTGOV.
 Always updated: As the Office 365 Automation suite is online, it gets updates directly and always provide the latest version
of programs to the users. It saves the time of reinstalling software's and prevent outdated services.
 Data backup and security: Office 365 Automation suite is used to provide the facility of encrypting and write-protect the
files to prevent their alteration. Besides this, it will prevent the threat of data loss due to any disaster or other factor.
Disadvantages of Office 365 Automation suite:
 Required high speed data transmission: Low speed internet will cause the user to lose the access of its files. The
requirement of speed internet will make it limited to be used by selective users.
 Subscription based: the Office 365 Automation suite is subscription based and requires a significant amount of money to be
spend to keep the work in progress. This can only be used by limited, Large enterprises.

How cloud services differ from on-site data centre
cloud services data centre on-site data centre
The servers in the cloud service data center will include the
integrated fault tolerant servers to store data.
This are based on a co dependent system which means that if
one server fails, the other shut downs.
It is monitored and controlled using automation tools. It includes the manual monitoring and data flow control.
The cost is based on per logical usage. It includes the physical machines.
Fixed at a designed server. Can be accesses through any VM.

Sharepoint

1 Difference between IaaS, PaaS and SaaS
IaaS PaaS SaaS
The applications and files are been
managed by the service users on their
personal level
This includes the management of
applications, software's and files with helps
of service provider.
In this system the data is effectively
managed by a remote service provider.
It has the OS on local device and run time
that provide the online visualization.
All the components are managed by remote
service provider and local owner in
collaboration.
Completely managed by remote service
provider.
Flexibility to change the configuration as
per the needs and requirement
The hardware can be altered but software
can be modified much.
Hardware and software, both can't be
modified.
Low cost Moderate cost Highly costly

2 Recommend the best suitable model for the incorporation of SharePoint services
 As per the assessment carried, For the operations of DTGOV using the SharePoint 2010, the incorporation of IaaS model will
be the best suitable and most appropriate.
 The initial level of moving to cloud service required the adaption of most basic model with higher level of flexibility to move
around the server types.
 This will improve the quality of web services offered to the users of the chosen firm and allow the organization to carry out
the operations will
 Help in setting up of the operations related to the usage of SharePoint 2010 services within organization.

3 Most likely problem faced by DTGOV and how it will deal with it
DTGOV will require looking after the issues like initial acceptance of the Cloud computing and automation. Besides this, the set up
expense is the another major issue faced by the firm. DTGOV will look after the measures like proper financial measures and
providing suitable training top the employees regarding cloud computing to deal with these measures.

CONCLUSION
On the basis of the operations which will help in carrying out of the cloud computing operations which will help in carrying out of
the activities which will help in improving the performance of DTGOV. This will help in improving the services with proper
automation and usage of Cloud computing tools.
