Project Architecture

The project has a classic Web-Queue-Worker architecture. The core component of this architecture are a web front-end that serves client requests, and a worker that performs tasks. The client communicates with the worker through a message queue.
More precisely -

1. Client : a java/python AWS project (with one class that includes main method). It is hosted on your machine (not on the cloud). This client does the following steps:
   • Creates an SQS Queue for requests (called the requestQueue) and use it to submit a request containing a list of maximum 10 integers (separated by comments).
   • Receives the response from the EC2 worker.

2. EC2 Worker: this is a java/python application that runs on an EC2 instance. It does the following tasks:
   • Reads the messages from the requestQueue
   • Calculates the results
   • Creates a response queue (called responseQueue) and submits the result on it.
   • Create a new log file (a text file) and store it on Amazon S3.

Go Further: the hot-dog application

You work for a very promising company which goal is to develop an app capable to recognize hot-dogs on images. To proceed, the company needs labeled data, meaning data with a label 1 when it represents a hot-dog ; 0 when it represents something else. You will create a new AWS application that shows a sample of images to a client, let the client label each of the data, and store that label in a table.
• The set of images available for labeling is stored in a S3 bucket
• The file storing the label information for each image is also on a S3 bucket
• Each client is shown 4 random images out of the total number of images that are in the bucket
• If multiple client are shown the same image, you should record each answer in the same text file
• A client can contribute and upload more hot-dog images to the bucket
• You are free to choose whatever images you want to build you set of images (you need around 20 images). Half of these images must represent hot-dogs.
• Choose small size image
