Learning Objectives

After successfully completing this assignment, students will be able to:

  • Configure, run, and test a linux server in AWS' EC2
  • Configure, run, and test a Windows server in AWS' EC2
Requirements
  1. Create an Ubuntu 20 LAMP server in EC2 like we did in class.
  2. Verify your that Apache was installed by opening your browser and enter the public dns of your server in the address bar. If it does not connect either you did not add HTTP to the Security Group, or the install did not work properly. Take a screenshot and save it (for submission below).
  3. The default location of html and php files is /var/www/html. Change to that directory. Now, using your favorite text editor use sudo to run your editor and create a file in that directory named info.php. For example, sudo nano info.php Then enter the following in that file to show information about the PHP installation: <?php phpinfo(); ?> Save the changes to the file and exit the editor.
  4. Now in your browser, enter the public dns of your server in the address bar / info.php. For example, my public dns was ec2-54-89-230-235.compute-1.amazonaws.com, so I enter  as the url. Take a screenshot and save it (for submission below).
  5. Create a Windows 2016 Server, like we did in class.  
  6. Login to it using Remote Desktop.  Take a screenshot of Remote Desktop connected to your Windows Server and save it (for submission below).
Clean Up

Now that you have completed the assignment, stop or terminate your EC2 instances. Stopping them means that it is now longer running, but your data is saved. That means you will not accrue charges on your running server. Terminating will both stop and delete the instances (also not accruing charges).

What to Submit
  • Screenshot of Apache page on your server shown in your browser
  • Screenshot of the PHP info page on your server shown in your browser
  • Screenshot of Remote Desktop session to your Windows Server

Objective: Take a sample feed, parse it, augment it, and output individual JSON objects for each product in it.

product.txt

  • The file contains several fields of basic product information for 1000 products.
  • Data for each product is on one line, with fields separated by a vertical pipe character.

This particular retailer classifies products into a particular store, department, category, and subcategory.

Example >

  • A Blender might have the following "taxonomy" or category classification.

Home & Garden > Kitchen & Dining > Appliances > Blenders

Store

Department

Category

Subcategory

store_id

department_id

category_id

subcategory_id

 

These IDs are also represented in a sort of shorthand.

  • They should all be prefixed by the first three letters of their respective field name.

A store_id of 1 becomes sto1

A department_id of 2 becomes dep2

A category_id of 3 becomes cat3

A subcategory_id of 4 becomes sub4

targets.txt

  • A system to keep track of these various classifications
    • Example
      • A store_id of sto40 maps to a “target value” of 187298 in PromoteIQ's system

Output Example:

The desired output for the first product is one line of JSON that when pretty-printed looks like:

{

  "sku": "22067130",

  "name": "Brainboxes ES-571 Brainboxes Es-571 Industrial Isolated Ethernet to Serial + Switch - 1 x Network (R",

  "description": "Brainboxes ES-571 Brand New Includes Lifetime Warranty Product # ES-571 Factory floors can be harsh environments.",

  "priceList": 387.95,

  "taxonomy": [

    "sto2",

    "dep7",

    "cat270",

    "sub18532"

  ],

  "targetValues": [

    187167,

    187177,

    187950,

    196404

  ]

}

 

The taxonomy IDs have been mapped to their long form and placed in the taxonomy property.

  • Each taxonomy ID has also been mapped to its corresponding target value ID from the targets.txt file
    • and that result is stored in the targetValues
    • The priceList property is the product price as a JSON float, not a string

X. Write a da Subway system in which you define a new type Subway System A Subway Systemen of a private ArrayList lines. No methasoher than the constructed the addline method should modify this array list. Your class should have the following co-static methods (25 points) • Write a c tor Subway system that takes thing asing and initializes the private property lines to be an empty mysl • Write a method adine which takes as input a MetroLine newline and acknowline to the array lest lines. The mathed should retun void • Write a method got Distance Travelled which takes as in ArrayList path and returns a double representing the tual distance travelled or a paththalpos from the first Metrostation in the anaylist, to the Metrostation to the third til the cod of the array listHe cach Metrostation along the joy the calculate the distance between the Metrostation and the prices. If the ArrayList Metrostation path is less than 2 vales, y mesh shox return On You may the wale path issul For m e, if the ArrayList Metrostation path five Metrostation you code calculate the sum of the distance between the fin d ing the second third the third and fourth, and lastly the fourth and final stations. Hint: To calculate the distance between two points, you can use a method defined in the appendix in the Maputilities class . Write a method findNearest Station which takes as input a double x and a double y ad the Metrostation which is nearest to the x and y. To do this, it should leather all the Metrostations of all the Metrotines inside of this lines and find the Metro Station that is the smallest distance away. You can use the same appendix method as in the precis i on You may assume that there is a leadine MetroLine defined in the property lines. You may also assume that every MetroLine in lines has at least one Metrostation in Hint There is no method such as getAll Station defined a Metrotine ohjeet. This is since providing this method would rewal a lot about the implementation of the Metrolines and would differ depending on the kind of collectice you are using to store it. However, you can simulate this art of method by using the get PirstStop () and get Next Stop () methods to access every entry of the AmyList. Remember the condition that will cause getNext Stop (to be null • A method qet Neighboringstations which takes input a Metrostation station and re- turns an ArrayList The Arrayut Metrostation whild consist of all nephring stations to station possibly many if the station in ce may lines). P erample, if statice is the 3rd stop on the blue line, the 6th stop on the red line, and the stop on the green line, then the mothed should return an ArrayList
