Cloud Computing: Technology and its Mechanisms Report

This report provides a comprehensive overview of cloud computing, detailing its infrastructure, logical network perimeters, and virtual servers. It explores cloud storage devices, levels, and technical interfaces, along with cloud usage monitor mechanisms, including monitoring, resource, and polling agents. The report also covers resource replication and ready-made environments, such as Platform-as-a-Service (PaaS). A case study of DTGOV organization highlights the practical application of these concepts, including the use of routers, DMZ zones, and firewalls. The report emphasizes the virtualization of cloud storage devices and their pay-per-use mechanisms. It concludes with references to relevant research papers and resources.

Cloud infrastructure mechanism
Cloud infrastructure is a foundation of
building blocks of different environments,
such as logical network perimeter, cloud
usage monitor, read-made environment,
virtual servers, resources replication, and
cloud storage devices (Schouten, 2014).

student name and number 4
Logical network perimeter
It is a isolated network environment that is
establishing a virtual network boundaries
Different purposes of logical network
1. it isolate IT resources from non-user in a
cloud
2. it isolate IT resources from non-authorize
users in a cloud (Dinh, Lee, Niyato, & Wang,
2013).
3. it isolate IT resources, such as bandwidth
for cloud consumers.

student name and number 6
Case study (DTGOV)
There are some critical requirements of
DTGOV organization to manage their
resources in proper way, which are as:
Routers for connecting extranet to internet
DMZ zone for creating virtual network
hosting for proxy servers of company (Garg,
Versteeg, & Buyya, 2013).
Firewalls to provide monitoring, controlling,
isolation of traffic, and filter network traffic.

Victual Servers
Virtual servers provide virtualization to
emulates a physical server s issues
It is used to resource sharing by cloud
providers (Krutz, & Vines, 2010).

Cloud Storage Devices Mechanism
Cloud base environment are having specific
storage devices (Mahalle, Yong, Tao, & Shen,
2018).
These devices have facility to be virtualized
 it has pay-per-use mechanism in which user
can pay and get fix-increment capacity in his
storage (Rittinghouse, & Ransome, 2016).

student name and number 11
Cloud storage level
Files
Blocks
Datasets
Objects

student name and number 12
Technical Interfaces to Storage
Network storage interface
Object storage interface
Database storage interface
1. relational data storage
2. Non-relational data storage

Cloud Usage Monitor Mechanism
Cloud computing has a software to manage
the processing and usages of IT resources
It maintain a record in metric, such as usage
time, amount of data, and many others

student name and number 15
Format of agents
Monitoring agent – it measure network traffic
and analysing data flows
Resource agent – it manages IT resources,
such as initiating, vertical scaling, resuming
services
Polling agent – it monitor uptime and
downtime of IT resources (Sen, 2014).

student name and number 16
Resource replication and 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).
