I've created an auction system which can auction bids and select the winning bid such that it always responds before a specific time interval
There would be following actors in the system
- Auction ID - Unique identifier for an auction round.
- Bid Amount - Floating numerical value of the bid amount.
- Ad Request - JSON with key of “auction_id”
- Ad Response - JSON with key of “price”, “bidder_id”
- Bidder - There would be specific numbers of bidders, which would respond to the bid request of the auctioneer with Ad Response from which auctioneer will determine winner of bid round, Bidder need to respond to the bid request with some amounts of delay (generally 10ms to 500 ms).
- Bidder system should accept following configuration parameters
- (i) Delay time in ms
- (ii) Port to bind as input
- (iii) URL to register itself with auctioneer
This is the main coordinator responsible for carrying out the bid rounds. At the start of each bid round this will take an ad request which would contain auction_id, which is the identifier of a bid round (random string). Whenever auctioneer receives a bid request, it will conduct a bid round, where it will query all the bidders for the auction. They will respond to the request with the above described behaviour and auctioneer will choose the highest bidder within 200ms and respond to the incoming request with an ad response. If no response is available from any bidder (they all decided to take more than 200ms for a request), send an appropriate HTTP status code.
- Auctioneer should expose following endpoints
- (i) Bid endpoint - This is where ad requests will be coming in.
- (ii) List endpoint - This endpoint will give registered endpoints.
- (iii) Registration Endpoint - This endpoint will be used to bidder to register itself to the bidder once it’s online.
- Install Golang and Docker on your system
- Clone this repo using
git clone https://github.com/shivamverma4/adrequestauctionsystem - Keep your Docker running, and create a docker image using command
docker build -t adrequestauctionsystem . - Now run this docker image with the docker IMAGE_ID, using command
docker run -d -p 8081:8081 xxxxxxxxxxxxx - Now the project is UP and running on port
8081 - Now you can create
auction, add registerbiddersand then start the bidding round with the bidders where the bidder with maximum bid wins the race
