Introduction:
Cloud computing is one of the popular systems in the cloud platforms
network. There are many data moving operations, and applied enterprises are
there, cloud computing systems are one of them. DAS means The Department of
Administrative Services, which is provided with some works to the Australian
Government. These services are included in the human resources, payroll,
contract management, procurement, and personnel management. For this
service, DAS provides all departmental data. Basically, for this reason, the
government policies have changed, and this Administrative service department
moved a different approached called "Shared Services" (Ali, Khan & Vasilakos,
2015). The meaning of this service approach is DAS will identify a new type of
service for the WofG means the whole of Government. These applications are
very much suitable for H.R., including performance management. The application
Resources are provided to cloud database systems in the U.S. (California). This
database is replicated and also spread in different locations like Ireland, Dublin
(Ghazizadeh et al. , 2014). All data are configuring correctly, and this data mainly
uploaded, maintained and also processed in the application provider processing
center. This center is located in Bangalore, India. Every day in 12 AEST DAS
uploaded their employee data and first this data transferred in Bangalore after
that this data loaded and delivered secondarily in U.S., California. Human
Resources information and performance management source are always
accessible by the employees. They are still able to use the agency identification
card via DAS internet. Every agency's working directory creates an internal
identity, and this is used for the authorization and authentications internally.
Some characteristics are directly related to the cloud computing are client server
model, grid computing, fog computing, peer to peer, utility computing
(Aljawarneh, Alawneh & Jaradat, 2017). Virtualization is the most enabling
technology of cloud computing. Cloud computing architecture are depending on
some service models like SaaS , PaaS, IaaS. Virtual machines, load balancers,
networking storages are came under the IaaS. Similarly PaaS are related to the
webserver, development tools and database. Mainly it is the platform of the
cloud computing. Lastly email, communication, games, CRM are related to the
SaaS. Basically this models are arranged in a layers of cloud computing. The
architecture mainly systemized by some model architectures and mechanism.
Some benefits are cloud computing are speed, integration, business planning,
choice, low cost and elasticity.

Explain issues
1. The Cloud-based service provides support for its users in different Australian
government firms. However, due to the change in new government policies in
Australia, the Cloud-based system of DAS will be more centralized and hence
provide access to the database to its various kinds of users (Berger et al., 2015).
2. . Due to the implementation of other government policies, the central
database of the company will be located in California, and the additional support,
maintenance, and processing center will be located in Bangalore
3. In modern databases, the concept of a data breach is perhaps one of the
most severe threats, where some unethical personal known as hackers tries to
gain access of these data such as own mail address and personal credit card
numbers of the employees which are further used by the hackers for their gain.
