Problem Description: Background Information:  Pioneer TAFE is an outstanding education and training provider. Apart from its current campus at  Brisbane, the TAFE has just built two new campuses in Sydney and Melbourne. The overall enrolment  of this TAFE is expected to increase after mid-2022. Currently, Pioneer TAFE uses a third-party  education delivery and learning environment called Blackboard. A number of challenges have been  observed during the COVID19 situation in the online delivery of the classes. To overcome these  limitations as well as to address the increasing number of students, Pioneer TAFE is looking for several  strategic upgrades to their current education delivery system. Two primary goals of this upgrade have  been discussed below. Your task will be to design suitable cloud-based IT systems to achieve these goals. 

Current Setup of Pioneer TAFE: Pioneer TAFE aims to create two high-end online laboratories – a data science laboratory, and a gaming  laboratory. The necessary setup and provisioning for the two laboratories will be implemented using  3 on-premise physical servers. The physical servers are located in the Brisbane (Server A), Sydney (Server B), and Melbourne (Server C) campuses. 

The physical servers are currently provisioned with  the following configuration:

• Memory and computing: All the 3 servers have equal computing and memory power currently.

• Threshold for the physical servers: The maximum number of virtual servers (VMs) each  physical server can host is 7. Currently, each physical server is hosting 6 virtual servers

. • Threshold for the virtual servers: The maximum number of cloud service instances each  virtual server can host is 6. Currently, each virtual server is hosting 5 cloud service  instances

. • Threshold for cloud service instance: Each cloud service instance can handle request from  1 student at a single point of time.

PROG2003 – Cloud Systems Development Assignment 3

• Current workload: The current student enrolment is 30 on each campus. With this  enrolment number, the physical and virtual servers currently are not fully utilised. 

Part A (25 marks): Design cloud system using appropriate cloud computing architecture(s) for the  following scenario. You can use commercial cloud provide and/or resources from the other two  campuses (Sydney and Melbourne campuses).

Scenario: The number of enrolments on the Brisbane campus (Server A) increases to 50. 

1) System 1: Design a cloud system to handle this scaling issue dynamically for the Brisbane  campus. Use appropriate/relevant cloud computing architecture(s). The design should include  a detailed diagram including all crucial components of the architecture. Critically discuss how  the system works and resolves the issue of increase enrolment

2) System 2: Now design an alternate system to address the scenario. Use a variant of the cloud  architecture used in Part A (1), different mechanisms with the cloud architecture used in Part  A (1), or a different cloud computing architecture. Draw a detailed diagram of the system and  discuss how it works 

Part B (25 marks): Design cloud system for the following scenario.  Scenario: Pioneer TAFE does not have sufficient resources to provision a specialised cloud service  offering machine learning features. The TAFE hires this cloud service from AWS. The data centre of  this AWS service resides in Ohio, USA. The TAFE collects attendance and personal information from  students which need to be stored. However, according to Australian data policy, the TAFE must store  all collected data in an Australian data centre. 

1) System 1: Design a cloud system that can handle this issue. Your proposed system should  include a detailed diagram and a clear discussion on how the system works. You can use  commercial cloud provide and/or resources from the other two campuses (Sydney and  Melbourne campuses) 

2) System 2: Pioneer TAFE aims to provision several ready-made environments (PaaS) for the  Melbourne staff. Design a cloud system to demonstrate how the TAFE will utilise its on premise infrastructures to create these ready-made environments. Use a detailed diagram to  illustrate the system
