Discussion 1: Beneficial uses of Cloud Computing Service and Deployment Models

Cloud computing typically offers businesses several advantages. The benefits include improved agility, reduced capital costs and enhanced flexibility with workload management. A number of cloud service and deployment models are available, and organisations have to make appropriate selections, to ensure that they make optimal use of cloud computing.
This discussion invites you to research and reflect on specific cloud service and deployment models that have been used by known organisations.
To prepare for this discussion, consider the following questions:
• Review the learning resources and media for this week
• Research online sources, including news articles related to cloud service and deployment models in use
• Reflect on your own personal experiences with cloud computing
Requirement

Create an initial post in which you present, and discuss, the cloud service and deployment models that have been used by a known commercial organisation. You can use an example from any business, charitable or government sector. Your write-up should describe the specific service and deployment models in use by the organisation, and why these were chosen.
Discuss any benefits accruing to the organisation from using a cloud-based system and point to any aspects of the service or deployment models that give comparative or competitive advantage to the organisation. You will be expected to cite academic and/or practitioner references to underpin your write-up.

Discussion 2: Virtualisation offered by mainstream cloud services providers

Mainstream cloud services providers use a range of virtualisation schemes within their cloud systems. Some of these are standardised whilst others are proprietary schemes.
Requirement

Create an initial post in which you characterise the types of virtualisations offered by at least two mainstream cloud services providers within their cloud systems. Your discussion should be reasonably concise and should present key virtualisation approaches and components used within the provider's systems. Point out the key features of the virtualisation schemes offered that enhance cloud services provisions for these providers.

Discussion 3: Network Virtualisation approaches used by IaaS cloud services providers

Mainstream cloud services providers use a variety of network virtualisation schemes within their cloud systems to support provisioning of network-attached resources for IaaS operation.

Requirement

Create an initial post in which you present the main features of the network virtualisation scheme used by a commercial cloud services IaaS provider. Your write-up should outline salient architectural features of the scheme used and should discuss how the provider's approach to network virtualisation helps enhance overall cloud services provision for clients.

Discussion 4: Cloud services PaaS database and data-warehouse management schemes

Amazon Redshift, RDS and DynamoDB are AWS PaaS products that have been developed to make it less onerous for clients to manage both commercial SQL and NoSQL database types. Clients are able to offload routing database maintenance to the PaaS subsystems layer.

Requirement

Create an initial post in which you discuss commercial or business applications for which the Amazon Redshift product would be well suited. What considerations would need to be taken into account if migrating data warehouses from legacy systems to the Redshift scheme?

Discussion 5: Mobile cloud computing and SaaS schemes

Mobile cloud computing systems have largely embraced SaaS, in its standard form and/or as MBaaS. Users and developers continue to seek newer and better ways for making use of SaaS-related technologies on a variety of mobile phone platforms.

Requirement

Create an initial post in which you present and discuss a specific mobile phone application or software product that has made significant use of standard SaaS or MBaaS technologies. Provide an overview of the architectural features of the SaaS/MBaaS scheme(s) used. In what ways has the application benefited from using mobile cloud SaaS?

Discussion 6: Cloud Infrastructure Security Issues
The security of data held on cloud systems has generally been a source of some concern, particularly given the spate of recent cyber-attacks and commercial security breaches.

Requirement

Create an initial post in which you present and discuss two security challenges facing commercial cloud services providers. Outline, using suitable illustrative examples, measures and approaches that have been used by CSPs to solve or mitigate these security challenges.

Your post may find it beneficial to refer to structured taxonomies for cloud-based security factors, domains and considerations, such as those put forward by the Security Alliance (CSA) and NIST organisations.

Discussion 7: Using Cloud Design Patterns (CDPs)

As was discussed in the lectures, cloud design patterns provide structured reproducible approaches to cloud systems development, based on several use cases and design scenarios.

Requirement

Create an initial post in which you present and critically discuss key attributes of two cloud design patterns offered by commercial cloud services providers. Explain what use cases the design patterns address and how they operate. You should select cloud design patterns that did not feature in the lectures or notes for the week.

Discussion 8: Cloud Services Standards and Regulatory Compliance

Cloud services providers have historically sought to ensure that their cloud systems adhere to industry standards and are compliant with mainstream regulatory regimes.

Requirement

Create an initial post in which you explain why and how commercial cloud services providers such as Amazon AWS and Microsoft Azure embed standards and regulatory compliance into their cloud operations. In your view, which compliance aspects have been the most problematic for cloud services providers to deal with?
