VIRTUALISATION AND CLOUD COMPUTING3IntroductionBefore discussing the benefits and issues that are related to the IaaS (Infrastructure as a Service) cloud, it is important to know the basics of IaaS and what are the key roles of IaaS and how it is useful for other types of infrastructures such as PaaS and SaaS. PaaS and SaaS are hosted on top of the IaaS which directly says that, if there are any breaches in IaaS, it will directly impact both PaaS and SaaS [CITATION Vee15 \l 16393 ].IaaS provides a set of resources such as storage, networks, servers, roll back virtual machines with which one can allow to run various application instances which will be available used to all the users who are connected to the internet. Once the platform is installed, users can freely install any application within the allocated resources that are made available to them. With IaaS, users have better control over security when compared to the other models till there are any loopholes in the virtual machine monitor. In this model, network and storage is generally controlled by the cloud service providers [CITATION Vee15 \l 16393 ].1 (a) The type of security to be deployed to protect this mission critical database once itis moved to an IaaS instance in a public cloud.Since the data will be shared on cloud, virtualization plays important role because virtualization will allow the users to share, create copies, migrate the data and roll back to thevirtual machines if necessary that will allow to run multiple application instances. Hence, virtual machine security will become more important such as physical machine security. Unlike to physical servers, VMs have boundaries which are physical and virtual.Security that has to deployed are:Usage of privileged access workstations [CITATION Sec17 \l 16393 ].Usage of multi-factor authentication system
