Question
System Analysis is used by various I.T. staff. Whether you are a System Engineer, System Analyst, or System Architect you will find some of the topics you learned throughout the semester valuable in your careers. Often system analysts task are broken up among task members in a group.
You will be asked to evaluate Cloud technologies just as you would evaluate technologies which are based on Prem (Local based Data Centers)
Depending on the response to Milestone #2 I will be detailing specific tasks for the remaining of the milestones for you to execute.
Milestone #1 - 10 PTS ==> Introduction to Cloud Computing & AWS
Milestone #2 - 5 PTS ==> Cloud Service Preference
Milestone #3 - 30 PTS ==> Project scope, use case definition and initial analysis
Milestone #4 - 20 PTS ==> Application Specifics
Milestone #5 - 35 PTS ==> Final Decision
Explanation / Answer
1-Cloud Computing:
Cloud computing is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the internet with pay-as-you-go pricing.
Whether you are running applications that share photos to millions of mobile users or you’re supporting the critical operations of your business, a cloud services platform provides rapid access to flexible and low cost IT resources. With cloud computing, you don’t need to make large upfront investments in hardware and spend a lot of time on the heavy lifting of managing that hardware. Instead, you can provision exactly the right type and size of computing resources you need to power your newest bright idea or operate your IT department. You can access as many resources as you need, almost instantly, and only pay for what you use.
AWS:
Amazon Web Services (AWS) began in 2006, offering IT infrastructure services to businesses in the form of web services -- now commonly known as cloud computing. One of the key benefits of cloud computing is the opportunity to replace up-front capital infrastructure expenses with low variable costs that scale with your business. With the Cloud, businesses no longer need to plan for and procure servers and other IT infrastructure weeks or months in advance. Instead, they can instantly spin up hundreds or thousands of servers in minutes and deliver results faster.
Milestone #2 - 5 PTS ==> Cloud Service Preference
1-Abstract:
The trust levels of cloud services should be evaluated to ensure their reliability. The effectiveness of these evaluations has major effects on user satisfaction, which is increasingly important. However, it is difficult to provide objective evaluations in open and dynamic environments because of the possibilities of malicious evaluations, individual preferences, and intentional praise. In this study, we propose a novel unfair rating filtering method for a reputation revision system. This method uses prior knowledge as the basis of similarity when calculating the average rating, which facilitates the recognition and filtering of unfair ratings. In addition, the overall performance is increased by a market mechanism that allows users and service providers to adjust their choice of services and service configuration in a timely manner. The experimental results showed that this method filtered unfair ratings in an effective manner, which greatly improved the precision of the reputation revision system.
Base Of work:
Reputation is a term that has different meanings in various domains. In our study, reputation is defined as an indicator of whether a user is willing to select a service based on the evaluations of other users. Thus, the result of a reputation evaluation will affect the decision about whether to interact with a service provider. Feedback related to previous interactions among users and service providers is collected by a reputation system to predict its future reliability [13, 14]. Reputation evaluations are essential parts of many recommendation systems [15]. Many systems are located in a central server, which can access, collect, and evaluate historical reputation scores from a large number of users [16–19]. Yang et al. [9] proposed a reputation management framework for service selection based on similarity theory. Different weights were set to compute the reputation based on the unique recommendations of users. However, the management framework was designed for a centrally controlled server, which was not suitable for a dynamic cloud service environment.
Milestone #3 - 30 PTS ==> Project scope, use case definition and initial analysis
Business analysts are equipped with two important tools for defining the project scoperequirements: context diagrams and use case models.
In software and systems engineering, a use case is a list of actions or event steps, typically defining the interactions between a role (known in the Unified Modeling Language as an actor) and a system, to achieve a goal. The actor can be a human or other external system.
Initial Analysis:The Project Initiation Document (PID) – or the Definition Document – is one of the most important artifacts in project management because it provides a foundation for the project. It specifies why the projectis important, what will be delivered, when it will be delivered and how.
Milestone #4 - 20 PTS ==> Application Specifics
It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computingresources (e.g., computer networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort.
