At your internship job, a senior programmer, Kamal, comments that Cloud computing was invented because of online shopping activities like Cyber Monday in the US, during which Amazon does over $3B in online sales, and Single Day in China, during which Alibaba does over $14B in online sales. a) Beri satu alasan dan terangkan kenapa ulasan beliau (Kamal) ini mungkin tidak benar. Give one reason and explain why his (Kamal) comments might be false. (2 markah/marks/C4) b) Berikan satu sebab dan terangkan kenapa ulasan (Kamal) ini mungkin benar. Give one reason and explain why his (Kamal) comments might be true. (2 markah/marks/C4) c) Tugas Kamal ialah untuk menukar aplikasi web dalaman kepada suatu aplikasi Awan yang elastik. Reka bentuk aplikasi web Kamal mempunyai satu mesin pengimbang beban di laluan rangkaian setiap http request sejurus sebelum mesin pelayan web yang beliau rancang untuk menyewa secara dinamik. Ali, seorang pelajar MMU yang melakukan satu temuramah pada hari semakan reka bentuk Kamal, mengulas bahawa mesin pengimbang beban ini mungkin tidak diperlukan. Berikan sekurang-kurangnya satu alasan ulasan Ali itu betul dan terangkan secara ringkas bagaimana mesin pengimbang beban ini mungkin boleh dihapuskan (iaitu, bagaimana pengimbangan beban boleh dicapai tanpa mesin). Kamal's job is to convert an in-house web application into an elastic Cloud application. Kamal's design has a load balancer machine on the network path of each http request immediately before the web server machines he plans to dynamically rent. Ali, a Mu student interviewing the day of Kamal's design review, comments that this load balancer machine might not be needed. Give at least one reason that Ali correct and briefly explain how this load balancer machine might be eliminated (that is, how load balancing could be accomplished without the machine). (4 markah/marks/C4) d) Ali juga menyebut bahawa jika Kamal ingin memiliki suatu aplikasi Awan mudah, maka aplikasi webnya mungkin mempunyai masalah untuk melaksanakan pangkalan data backend. Berikan sekurang-kurangnya satu alasan bahawa pangkalan data backend mungkin menjadi satu bahagian yang sukar dari aplikasi Awan elastik Kamal. Ali also mentions that if Kamal wants to have a simple Cloud application, then his web application might have problems implementing its backend database. Give at least one reason that the backend database might be a difficult part of Kamal's elastic Cloud application. (4 markah/marks/C4)
