Question

Different industry analysts are forecasting that Apple will replace Intel for ARM-based processors in
their Mac computers running macOS by 2020. Arguably, virtualisation can help Apple to ease the
transition.
a. Name the 5 Levels of Virtualisation
b. Choose one level from the five above which can enable macOS applications in this transition,
justifying your choice via its possible advantage(s) and disadvantage(s).

Answer 1

(a) Five Levels of Virtualization are:

(i) Hardware Virtualization.

(ii) Application Virtualization.

(iii) Storage Virtualization.

(iv) Desktop Virtualization and

(v) Network Virtualization.

(b) Among the five levels hardware virtualization can enable macOS applications in this transition. The advantages are:

(i) In this type of virtualization the virtual machine manager calls the hypervisor. The hypervisor consolidates the created virtual machines and operating systems to a physical server. This provides efficient operation.

(ii) The resources are utilized properly.

(iii) It provides CPU virtualization which can enable macOS applications in this transition.

There are some disadvantages of this approach like:

(i) The implementation is complex.

(ii) This approach is costly.

Hope this helps.
