The applications suite will comprise a mix of bespoke software developed to manage various HR functions e.g. employee data, job-related information, appraisals/performance data as well as self-service portlets for leave applications and promotion requests.

Last week, you started to prepare reasonably detailed advice for planning and scoping purposes for the cloud-based system to be developed.

Carry out the following tasks –

1. Explain, in some detail, which aspects of AWS would be relevant or influential for the planned cloud-based systems development. Structure your write-up here in terms of Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) issues and considerations.

2. A key aspect of the work will involve designing systems for storing and manipulating structured (relational) and semi-structured (key value and document-oriented) data. Discuss which aspects of AWS could be used to support this aspect of the HRM applications development.

3. Dealing specifically with the development of online self-service portlets for the HRM application, outline the general scheme of work that would need to be carried out with AWS to implement this. You should make reasonable assumptions pertaining to the type of application being developed, and anticipated user requirements.
