SECTION B - Short Answer Question
Scenario - Guitars, Amps and Pedals (GAP) is a fictitious national company that owns and runs retail and teaching stores throughout major cities of Australia, including an online store. Their administrative headquarters are located in Melbourne, some administrative functions are accessible online too.
GAP has contacted you to be their cloud computing consultant, and its management want to know about cloud computing. Additional details about this company are:
- GAP's product lines are all based on acoustic and electronic musical instruments and associated paraphernalia, including guitars, pedals, drums, keyboards and amplifiers.
- GAP also has income and expenses from their teaching services.
- As GAP is very popular, it has a large customer base which can cause high workload throughout the year at both unpredictable and seasonal times. As GAP management pride themselves on their online web presence being always available with fast response times, they support this by a large number of servers on-premise to handle workload distribution but also a by engaging a cloud provider for the occasional burst-out.
- A large amount of data related to GAP products and customers is collected and stored. It is processed as big data on a weekly basis. GAP's big data is stored in a cloud and as the number of requests to process their big data fluctuates to extreme levels, GAPs management ensure that all big data requests are completed within a reasonable time by employing a cloud provider to listen to and act on such fluctuations in demand.
- GAP staff located at their headquarters must work as a team covering several sites and in many aspects such as buying, marketing, seasonal sales, distribution, reports, big data analysis, etc.
1. Cloud Computing
(a) Briefly describe cloud computing as if you are describing it to the CEO of GAP.
(b) Briefly describe cloud computing as if you are describing it to non-IT administrative staff of GAP, these staff have a computer on their office desk and frequently use this computer on a daily basis.
2. Cloud Features
(a) Provide a list of 4 features that are essential to clouds and would be useful to GAP?
(b) Briefly explain why each is useful to GAP.
3. Cloud Benefits
(a) Provide one reason why GAP would benefit by using a cloud system to carry out their computational tasks?
(b) Provide one reason why GAP would benefit by using cloud storage?
SECTION C - Design
Scenario - ABC University is a fictitious private university undertaking teaching at several campuses throughout major cities of Australia, including online teaching. Their administrative headquarters are located in Melbourne and some administrative departments are spread across each campus, some administrative functions are accessible online too.
ABC has contacted you to be their cloud computing consultant, and its management want to know about cloud computing. Additional details about this company are:
- ABC's product lines are all based on degrees, including Associate, Bachelor, Honours and Masters by course work. ABC is not involved in research at any level.
- ABC also has income and expenses from selling courses to other universities, and teaching partnerships with other universities.
- As ABC is very successful and claims high integrity. It has a large national and a larger international student base which can cause high workload throughout the year at both predictable and unpredictable times. ABC management pride themselves on their online web presence, for both students and staff, being always available with fast response times from within Australia, they support this by a large number of on-premise servers to handle workload distribution but also by engaging one or more national or international cloud providers for the occasional burst-out.
- A large amount of data related to student assessments is collected and stored. It is processed as big data on a weekly basis to detect plagiarism. ABC's big data is stored in their private datacentre and as the number of requests to process their big data fluctuates to extreme levels, ABCs management ensure that all big data requests are completed within a reasonable time by employing a cloud provider to listen to and act on such fluctuations in demand.
1. Data Centres
Provide a list of the different kinds of datacentres that will be required for ABC's cloud based system.
2. Cloud Based System Design
