Cloud Computing Report: Infrastructure, Services, and Usage Mechanisms

This report provides a comprehensive introduction to cloud computing, exploring its foundational aspects and various service models. It begins by defining cloud infrastructure as a complete solution for organizational operations, detailing services like data storage and software development kits. The report then delves into the logical network perimeter, emphasizing its role in securing IT resources and providing secure access. A case study on DTGOV illustrates practical applications, highlighting the use of routers, DMZ, and firewalls. The discussion extends to virtual servers and cloud storage devices, explaining their virtualization capabilities and pay-per-use mechanisms. Technical interfaces, including network, object, and database storage interfaces, are also examined. Furthermore, the report covers cloud usage-monitor mechanisms, discussing monitoring and resource agents, along with resource replication and the Platform-as-a-Service (PaaS) model. The content is supported by multiple references to enhance understanding.

Cloud Computing

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).

Objects
Files
Datasets
Blocks

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

student name and number 14
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).
