Form a group of three students and inform your laboratory tutor of the names and student IDs of your group members. Choose one (1) scenario given in the list below as your assignment topic. Assume that your group has been hired by the client company to develop a networked system for their required services as described in your chosen scenario. Your task in this assignment is to (i) analyse client requirements, (ii) design the solutions, (iii) implement, configure, and troubleshoot implemented solutions, and finally, (iv) prepare a system documentation report meeting the client requirements and following a standard industry template. Detailed requirements are provided below:  
1. For your chosen scenario, (i) analyse client requirements, (ii) identify and propose the required servers and server roles (services), and (iii) provide required configurations for your chosen scenario.  
2. Perform the configurations using either virtually or physically installed server OS for your chosen scenario. Students can use Windows Server 2008 or a higher version, or Linux server if appropriate, which will depend on the scenario chosen. Your submission should include screenshots of each important step.  
3. Prepare a detailed system documentation report to record your work done in steps 1 and 2 above, using a standard template. You have the freedom to create a template, with company name, logo, etc., for your client and use that for your documentation report. This report will serve as an important part of backup and disaster recovery documentation for the organisation in your chosen scenario, and can be used for training new IT staff in the organisation. As such, you must consider human usability factors and include the configurations using a description of each important step, and screenshots corresponding to those in a way that will be useful to the target users of the document. Essential sections that must be included in the documentation are provided in the marking guide, however, you can include additional sections if deemed useful.   
You must configure the domain(s) using group members’ names (e.g., sajeen-joy-sam). If the chosen scenario requires a web server, the group must create a simple webpage (using html header tag only) to display the company’s name, and student ID numbers of the group members; this page needs to be stored on and displayed from the created web server.    This documentation report (one report per group) is to be submitted on Moodle in Week-11.   
4. Use your configured system to demonstrate individually your understanding of the implemented scenario during your week-12 laboratory class.

Cloud computing

Written by Friday, 28 September 2018 15:22

Webb’s Stores is a successful regional retailer that operates stores in Australia and also in New Zealand. Webb’s sell a range of food stuffs as well as some speciality items. The company has two main data centres, one located in Sydney and the other in Melbourne. It also has a number of regional data centres located in Wagga, Bathurst, Port Macquarie, Brisbane and Auckland in New Zealand.

Webb’s Stores has engaged you as a consultant to advise them on the use of Cloud Computing in their daily operations. They have some 600 sales staff that work in their stores and 200 staff that work in their two main warehouses in Sydney and Melbourne. Webb’s have been facing increasing issues with application and operational complexity and the management of their data. They have been advised that a move to using a Cloud based infrastructure would be an advantage to them.


Webb’s has recently taken over a group of small independent grocery retailers in regional Victoria. They need to integrate this new retailer into their operations as soon as possible.
The Board of Directors of Webb’s has decided that they will use this new regional group of stores to test their strategy of using the Cloud to better integrate their operations.Your task is to:


1. Prepare a PowerPoint briefing for the Directors of Webb’s Stores. Your briefing should:

a. Describe the key concepts of Cloud Computing and why do you think that a move to the cloud will benefit Webb’s Store.
b. Explain how Webb’s could use either AWS or Azure to integrate their new regional group of stores into their existing operations. 
c. Explain which cloud architectures you could use to integrate these operations and the reasons for their use.
d. Each slide in the briefing must also include speaking notes in the notes section to explain the slide, and all images used in the briefing should be referenced. 
 

2. The Board of Webb’s is considering moving to a SaaS model for providing email and office automation services (this includes mainly word processing, spreadsheets and presentation software such as PowerPoint). There are a number of providers of these services that are now available and you are asked to recommend one of these services to Webb’s. You are to prepare a PowerPoint briefing for the Directors that includes:

a. The advantages that Webb’s can achieve if they use this type of SaaS service,
b. The disadvantages that Webb’s will face from using this type of service,
c. The SaaS service that you would recommend, including:

i. The name of the service
ii. How it is better than other similar services?
iii. What are its specific disadvantages?


3. Webb’s Stores has data centres in Sydney, Melbourne and Brisbane that run MS SQL Server 2012 R2 databases. These databases form the operational core of Webb’s. These data centres are linked by a fibre based WAN and data is replicated between the data centres daily. The 3 data centres each run x86 based servers attached to a HPE 3PAR SAN with 1PB of storage. The databases in each data centre are stored on the SAN. There is a copy of this database at the Auckland data centre, but they are having issues replicating data to Auckland because of latency and other issues. Webb’s is now considering moving its databases into the cloud to resolve this issue. But they are unsure of the issues that are involved with this migration. You are to write a report for the Webb’s board that:


a. Describes the differences between using:


i. An IaaS approach to migrating Webb’s database to the cloud, and
ii. A PaaS approach to migrating Webb’s database to the cloud.
iii. Create a table that shows the advantages and disadvantages of each approach,
iv. What is the approach that you would recommend and give your reasons for recommending this approach
