Cloud Computing: Infrastructure, Network Perimeter, Case Study, Virtual Servers, Storage Devices, Interfaces, Usage Monitoring

This presentation provides an overview of cloud computing infrastructure, including logical network perimeter, case study, virtual servers, cloud storage devices, technical interfaces, and cloud usage monitoring. It discusses the foundation of cloud infrastructure and its building blocks, such as logical network perimeter and virtual servers. It also explores the mechanism of cloud storage devices and the different levels of cloud storage. Additionally, it covers the technical interfaces to storage and the monitoring mechanism in cloud computing. The presentation includes a case study on DTGOV organization and their requirements for managing resources. Overall, it offers insights into the disruptive technology of cloud computing.

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.

Logical network perimeter (2)

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).
