This question part is about parallelisation. Suppose the execution of a video rendering job using 2 VM on an IaaS cloud takes 6 hours for a total cost of £4. The job is composed of rendering 100 short videos. Consider what would happen if 4 VMs are used to execute the same job. Answer the following questions (state any assumption you make as part of the answers).
(i) Say if the total cost and the time to complete the job would stay the same, reduce, or increase and by how much. Justify your answer
(ii) Now consider the case of a rendering job with the same characteristics (6 hours, 2 VMs cost of £4) but is instead composed of rendering 2 long videos. What would happen to the time and total cost if 4 VMs are used to run the job? Justify your answers.
