For this assignment you will research the performance specifications of commonly used disks as well as the impact of configurations such as RAID etc on those performance characteristics.   You will also research the common storage performance needs of server operating systems and applications and see how this compares to the performance characteristics you found for common systems. Be sure to detail how you the information you gathered would impact your decisions on implementing a disk.   Highlight in your response how you think these items can be resolved and what needs to be kept in consideration when designing a virtualized system. Your submission needs to be in one of the following formats .doc, .docx, .pdf or .odf

Please read the attachment carefully ! 

Start your paper with an introductory paragraph.

Prompt 1 “Data Warehouse Architecture” (2-3 pages): Explain the major components of a data warehouse architecture, including the various forms of data transformations needed to prepare data for a data warehouse. Also, describe in your own words current key trends in data warehousing. 

Prompt 2 “Big Data” (2-3 pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology? 

Prompt 3 “Green Computing” (2-3 pages):  One of our topics in Chapter 13 surrounds IT Green Computing. The need for green computing is becoming more obvious considering the amount of power needed to drive our computers, servers, routers, switches, and data centers.

Write a program to apply Machine Learning classification models to Iris flowers dataset. Follow the steps:

1.Download the iris.csv file (example: https://gist.github.com/netj/8836201). From this file the label (target) is defined with the ‘variety’ column and the features with ‘epal.length’, ‘sepal.width’, ‘petal.length’, ‘petal.width’ columns.
2.Preprocess the iris.csv file by label encoding the target ‘variety’ column.
3.Apply the following Machine Learning classification models: K Nearest Neighbors and Random Forests
4.Calculate the following classification metrics to validate the model: Accuracy Score, Confusion Matrix and Classification Report.
5.Explain how the program works and compare these two classification models.

A new medium-sized health care facility just opened and you are hired as the CIO. The CEO is somewhat technical and has tasked you with creating a threat model. The CEO needs to decide from 3 selected models but needs your recommendation. Review this week’s readings, conduct your own research, then choose a model to recommend with proper justifications. Items to include (at a minimum) are:

• User authentication and credentials with third-party applications
• 3 common security risks with ratings: low, medium or high
• Justification of your threat model (why it was chosen over the other two: compare and contrast)

You will research several threat models as it applies to the health care industry, summarize three models and choose one as a recommendation to the CEO in a summary with a model using UML Diagrams (Do not copy and paste images from the Internet). In your research paper, be sure to discuss the security risks and assign a label of low, medium or high risks and the CEO will make the determination to accept the risks or mitigate them.
