Virtualization
Virtualization in cloud endorses the partition of single server into multiple servers.
Virtualization in the cloud server can be defined as the masking of the server resources. Virtual
server runs in its own operating system and applications. The virtualization in the cloud
computing provides a way for saving the cost and increase the utilization of the single server.
There are different types of virtualizations like para-virtualization, full virtualization. The
selection of the type of virtualization is dependent on the requirements.
There are different cloud servers provides the virtualization facility. Two of the main
stream cloud service provider offers virtualization are- Amazon cloud and IBM cloud.
Virtualization in AWS
There are two types of virtualization provided by Amazon AWS. These are- Pare virtual
and hardware virtual machine. Each of the virtualization technique has its own advantage and
disadvantage. AWS uses bare metal or Xen hypervisor for the virtualization. The working of the
virtual machine is carried out on the top of the hypervisor (Dalton et al. 2018). The scheduling
and partitioning of the memory is done by the hypervisor but it cannot control networking and
extreme storage and other input output functions.
Hardware virtual machines are fully virtualized. In this case, the virtual machines running
on the top of the hypervisor is independent of the other applications or the client running on the
same system. The lighter form of virtualization is called Para virtualization. In this environment,
some of the modifications are needed in the guest system before it starts working (Ibrahim,
Hamlyn-Harris and Grundy, 2016). On the other hand, in the full virtualization, there is no need
for the modifications in the guest system. Full virtualization provided by Amazon can be
