Virtualization, IT Infrastructure, and Cloud Security Issues

This report provides an overview of various virtualization techniques, including application, network, storage, and desktop virtualization. It discusses the roles and responsibilities of an IT infrastructure manager, covering aspects like establishing standards, staff management, vendor management, strategy, and monitoring. The report also explores IT infrastructure solutions for dynamic scaling of applications, emphasizing the role of cloud computing. Furthermore, it addresses critical cloud computing security issues such as distributed-denial-of-service attacks, shared cloud services vulnerabilities, employee negligence, data loss, phishing attacks, and system vulnerabilities. Desklib offers similar solved assignments and past papers for students.

Application Virtualization: The application virtualization is also known as the process virtualization. The application virtualization is achieved through some kind of software processes
which helps to encapsulates the testing program from the operating systems at the time of execution of the software.
Network Virtualization: The network virtualization is very much important concept in aspects of cloud computing. In this case the network virtualization can be demonstrated as the com-
bining process of the hardware and software resources.
Storage Virtualization: The storage virtualization is considered as the process of logical presentation of the physical storage resources to a host computer. The main idea of the storage vir-
tualization is treating all types of storage media as a single storage pool within enterprises.
Desktop Virtualization: The Desktop virtualization considered as the technique of isolation of the logical operation system instance from clients who generally access this OS. There are
many different conceptual model regarding virtualization of the network.
IT infrastructure solution for dynamic
scaling of applications :
The scalability is the factor of system which
indicates that every application or the infra-
structure within a system is capable of han-
dling the increased load when there is a high
amount of pressure. It has been assessed that
to ensure a perfect scalability the cloud com-
puting plays a major role as the web applica-
tions of virtual machine, front end load bal-
ance, service monitor system and provisional
system is required.
Cloud Computing Security Issues:
1. Distributed-Denial-of-Service Attacks
2. Shared Cloud Computing Services
3. Employee Negligence
4. Data Loss and Inadequate Data Backups
5. Phishing and Social Engineering Attacks
6. System Vulnerabilities

sponsibilities of an IT infrastructure manager:
