Starting Simple © 2019, DL, UTA

Getting Started
• Using a “public” cloud service provider
• There are many, the big ones used in this class: • IBM Cloud (BlueMix)
• Azure (Microsoft Cloud)
• AWS (Amazon Web Services)

Getting Started
• Using a “public” cloud service provider
• Why “public” cloud service?
• (Don’t want this to be a distributed computing class. Available. Useful skills. Many services.)
• Why these?
• (Biggest, oldest, most services. Free. Different Approaches.)

Getting Started
• Using a “public” cloud service provider • Caution:
• The service you get for free is limited! More than enough for this class, but not “infinite”.
• Be very, very careful with your credentials!

First Assignment
• Part 1:
• Need to start with a public cloud service provider
• IBM cloud (https://www.ibm.com/cloud/) is free, and gives you lots of service for free.
• Sign Up.

First Assignment
• Part 2:
Task: You are will create a cloud-based picture and associated information
storage and retrieval system with a (local) web interface (UI)
Description:
One of the most common uses of “Clouds”, is shared or backup storage. SaaS, with afriendly interface.
Your assignment is to provide a local interface to a cloud service that you will implement that will allow a user to upload a meta-information table “people.csv”,a .csv (text) table followed by several individual pictures. Then the user may do queries that select some (or none) pictures, specified in the people table.

Abhishek,100000,550,20202020,abhishek.jpg,Abhishek is almost done and very smart Jees,99099,420,,jees.jpg,Jees is too
…

First Assignment
• Part 2: And your
+ Add a picture for Dave
+ Remove Dave
+ Change Jees’s keywords to “Not so nice anymore” + Change Someone’s salary
And similar…
cloud-based “service” will allow a user to:
for Jason (Name) and show his picture on a web page.
for (display) all pictures where the salary is
less than 99000.
+ Search
+ Search

First Assignment
• Part 2:
You may use any reasonable (non-hardcoded) implementation of the
people table:
Hashes, a SQL (or non-) table, or even a dictionary or array.
Pictures are binary entities stored on the cloud provider storage, in any manneryou wish (files, DB tables, hashes, etc.).
You should handle conditions such as: missing data (fields, attributes), unavailablepictures, attempts to upload the same named picture twice, pictures that are of incorrecttype (“dave.txt”), and similar.
