Assessment - Concepts and Models

Task

Read the DTGOV Case Study before you attempt this assignment

DTGOV want to migrate some of their webservers to an IaaS instance in AWS to test their strategy. They understand that they need to do a full migration plan first, but they want to determine what sort of architecture would be required to support their web services.
The web services are considered essential by both DTGOV and their users, so any web services must be:
• Readily available and accessible at all times
• Capable of handling heavy loads in times of peak demand
• Capable of serving downloads to users as required
• Secure from attacks
• Capable of providing reports on usage

Your task is to prepare an initial PowerPoint briefing for the DTGOV board. Your briefing should discuss:

1. Initial Webserver trial:
1. Explain how the selected DTGOV webservers will work in an IaaS instance in the AWS Cloud environment and how will this move affect users of these web services. You should also explain if you think the users will benefit from this move, and why they will benefit, or not;
2. Explain the types of Cloud Architectures that you think would be useful for DTGOV to use as part of their webserver infrastructure in the Cloud. This explanation should also briefly discuss how the current DTGOV infrastructure could be replicated or replaced in a Cloud deployment.
3. You do not need to talk to security of the infrastructure or webservers in this briefing.
2. Office 365:
1. Many of DTGOV's customers want to provide all their staff with the ability to access office automation, such as email, word processing and spreadsheet capabilities, as well as online storage for their files, whether they are in the office, at home, or working at a remote site in the field. The DTGOV board is very concerned to learn about the critical issues, other than cost, that may affect the supply of Cloud based office automation to their customers' staff. You will need to prepare a briefing on the best way to provide office automation for DTGOV customers. Your presentation should:
Discuss the benefits and issues that DTGOV customers, and their users, would achieve from moving to Office 365 as their office automation suite.
Describe how a cloud-based approach will differ from providing this suite from an on-premise data centre.
3. SharePoint:
1. DTGOV is also considering whether to use PaaS or SaaS to provide some services to specific customers. DTGOV has deployed Microsoft SharePoint 2010 from its data centre as a collaboration and document management tool. The SharePoint 2010 instance has been extensively customised to suit DTGOV requirements and deploys Project Central, their Project Management tool as a separate application from within SharePoint. DTGOV would like to move its SharePoint 2010 instance to the cloud to make it more available to more customers, particularly those at remote sites. DTGOV wants you to report on:
What are the major differences between the models IaaS, PaaS and SaaS?
Recommend the model that you consider most appropriate for this service and discuss why this model is the most appropriate for the SharePoint service.
What are the most likely problems that DTGOV will encounter with the model that you recommend? How would you advise DTGOV to deal with these issues?
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.

Assessment - Applied Cloud Concepts in AWS

Task
Read the DTGOV Case Study before you attempt this assignment
Overview
This assessment item requires you to produce a short report by investigating and advising technical users of DTGOV on some key topics and aspects of the use of Cloud technologies.

Task
DTGOV is starting to migrate some of its applications and services to a public cloud. Many of the technical staff have had no experience in the Cloud and are concerned about this process. You have been asked to create a WordPress site on AWS where staff can share their

experiences and ask other staff members about problems and issues that concern them.

1. You are to produce an instruction manual that describes:
1. How to create a WordPress instance on AWS. This instruction manual must:
Describe all the steps that are required to access AWS and create a working WordPress instance,
Include screenshots of each step of the process, along with sufficient explanatory text to ensure that another user could follow the instructions without problems.
2. Your WordPress site should contain brief instructions for users on how to add comments and photos or screenshots to your site.
1. These instructions must also be included in your instruction manual, along with a screenshot of the completed site.
3. Your instruction manual should also contain brief instructions on:
1. How to secure your WordPress site,
2. How to provide users with secure access to your WordPress site.
You should use your AWS Educate account to create your WordPress instance. AWS has provided a tutorial to take you through the process of creating a WordPress site.

You are not required to create or write any other text on your WordPress site. You are also not required to implement secure access for users, but you must have investigated this process. You are also strongly advised to shut down your site as soon as you have completed all tests and documentation.

Assessment item - Risk, Security and Management

Task
Read the DTGOV Case Study before you attempt this assignment
A chief strategic objective of the standardisation of DTGOV's service portfolio is to achieve increased levels of cost-effectiveness and operational optimisation.

DTGOV is considering the following strategic proposal:
• They plan to retain one (1) of their three (3) data centres solely for data storage. This would entail updating their Active Directory and data storage infrastructure, and moving all other infrastructure into the Cloud.

• They plan to initially move all their Web Services into the Cloud in order to provide an increased level of HA (High Availability) as well as a better degree of flexibility in supplying data to their customers and employees. This would entail changing their current web software architecture to take advantage of the flexibility and scalability that can be gained by moving to a Microservices model (this would entail the use of such services as AWS Lambda or Azure Functions, Containers, Data Services, and Cloud Edge capability and monitoring).
• They also plan to migrate their LoB (Line of Business) applications to Public Cloud infrastructure to increase their flexibility and availability.
The DTGOV Board is contemplating this strategy as a way to increase the company's flexibility and responsiveness. The Board also expects to achieve significant savings on the cost of maintaining their ICT infrastructure by eventually closing the other two (2) existing data centres. They appreciate that this would entail retraining for their existing ICT staff so that they can manage the new Cloud based infrastructure.
DTGOV has again approached you to advise them on this strategy. You have previously advised DTGOV that this strategic approach will mean that they will need to ultimately design and operate a "Hybrid Cloud" methodology, where part of their data centre is "on premise" and another part in a Cloud.
DTGOV also plan to run a Risk and Security Workshop to assess the risks, security issues and possible methods of control that will be required with this "Hybrid Cloud" approach. You will be required to organise, run and facilitate this workshop.
The Board is also concerned about how this strategy will affect their BCP (Business Continuity Plan) and their backup and disaster recovery strategies.

Tasks
Your team has been engaged to provide a report for DTGOV in their planned move to a Hybrid Cloud strategy.

Team Setup
This assignment is a team assignment. The rationale for using a team approach is that most IT risk management assessments are normally done by teams of between 2-5 Architects, Information Security experts, Operations and Business leaders for each problem. You will be assigned to a team and the team, as a whole, will be responsible for the development of the risk assessment.

Team Member Responsibilities
Each team member will be assessed on:
• The final risk assessment presented by the team;
• The individual contributions that they have made to the risk assessment. This will be shown by the entries that they have made in the Team forum;
• Team members should note that:
A total of 20% of the total marks for this assignment are for individual contributions to the team task;
A team member without any individual contributions in the Team Forum will be regarded as having not contributed to the risk assessment. This will result in either reduced marks or no marks being awarded to that team member for this assignment.

The tasks:
The team's task is to prepare a report for DTGOV that discusses the following:

1. Describe which Cloud architectures you would employ to assist DTGOV to meet the Board's strategy?
1. Describe each of the architectures that you would use, along with your reasons for deploying it.
2. Describe the benefits and issues that would be the result of your deployment of these architectures.
2. Describe the risks that you see associated with this new Hybrid Cloud and Microservices strategy. You should name and describe each risk that you identify, and then describe a possible control for the risk. This should be presented in a tabular form.
3. Describe the general Information Security steps and controls that you would recommend to the Board to secure the Hybrid Cloud. You will need to explain to the Board your reasons for recommending these particular security steps.
4. Discuss briefly what you would recommend should be included in DTGOV's BCP as a result of their adoption of a Hybrid Cloud and Microservices approach. You will need to consider, as a minimum, the issues of application resilience, backup and disaster recovery in a Hybrid Cloud environment. This section should be no more than 2 pages.
5. Discuss the requirements that DTGOV will need to consider in order to conduct remote server administration, resource management and SLA management for its proposed IaaS and PaaS instances (it may be useful to consider Morad and Dalbhanjan's operational checklists for this section). This section should be no more than two to three pages in length.
