O my Lord! Expand for me my breast [with assurance] and ease for me my task and untie the knot from my tongue that they may understand my speech. (Ta-Ha:25-28)

Virtualization

▪ Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources.

Benefits of IaaS

VoIP (Voice over Internet Protocol)

▪ Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

Conclusion

A centralized security solution is more suitable for cloud-based services because it never requires the intervention of end users. However, the end user can protect the network by means of hardware and software based solutions, which are already implemented by their respective networks. With the centralized approach, the management of VM-VoIP services and the configuration of the cloud services for threats will be easy for the administrator. Moreover, the SLA-based agreement will also help cloud service providers prioritize the traffic. This proposed solution is good enough small number of VoIP users. However, to utilize VM-VoIP in a bigger environment with best of QoS services, security shield should be isolated from VM-VoIP.
