Introduction
Cloud infrastructure is a complete solution of
all the problems. It provides all the solutions,
which are related to the organization's
operations (Schouten, 2014).
Cloud infrastructure mechanism provides
different services, such as data storage,
software development kit, and many others.

Logical network perimeter
Virtual private network provides a different
network environment to the organization for
security purpose
Different purposes of logical network
1. it secure their IT-sources from unauthorized
access
2. It provides secure access t internal and external
sources (Dinh, Lee, Niyato, & Wang, 2013).
3. It isolate IT resources of an organization, such
as servers, data storage and bandwidth for cloud
consumers.

Case study (DTGOV)
DTGOV requires many resources to manage
their operations which are as mention below:
1. Routers : it connects external network from
internal network and forward data packets to the
desired node (Garg, Versteeg, & Buyya, 2013).
2. DMZ : it is a secure zone for creating virtual
network hosting for proxy servers of company.
3. Firewalls : it is used to provide , controlling,
isolation of traffic, monitoring and filter network
traffic.

Victual Servers
Virtual servers provide virtualization to
emulates a physical server s issues
It is a best way to remove physical server
problem for an organization (Krutz, & Vines,
2010).
Cloud-based server is provide it for resources
sharing in between different clients

Cloud-Storage Devices Mechanism
Data storage is an important service of
cloud(Mahalle, Yong, Tao, & Shen, 2018).
 it provide a virtual storage to save and
secure data.
These devices have facility to be virtualized
This services is based on the pay-per-use
mechnishm (Rittinghouse, & Ransome, 2016).

Technical Interfaces
Network storage interface: provides virtual
data storage
Object storage interface: provide instance of
stored data
Database storage interface
1. Relational data storage
2. Non-relational data storage

Cloud Usage-monitor Mechanism
Software is used to manage all the
processing and usages of different sources of
cloud
It has a record of all the activities in the
cloud, such as usage time, amount of data,
and many others
Provide a analysis report to monitor
suspicious activities in the network

Format of agents
Monitoring agent – this agent is used for
monitoring different activities (Sen, 2014).
Resource agent – all the IT resources are
managed by resource agent such as initiating,
vertical scaling, resuming services
Polling agent – this agent is responsible for
uptime and downtime of IT resources

student name and number 15
Resource replication & Ready-made environment
It is a concept that makes multiple instances
of the same IT resources
Platform-as-a-Service (PaaS)- it is a platform
that have all the IT resources, which are
required by the user, such as software
development kit (Zhang, Wuwong, Li, &
Zhang, 2010).
