Right from start, this project necessitated creation of design which is scalable in the cloud.
The data-store needed to be cloud based.
Basically each user had 2 sets of data – opponent list and location list. He could add values to this data set any time through the log form.
For each user, we have created json location file and json opponent file to store data on S3/Cloudfront. Hence user data is loaded very fast, without any serve load. Whenever user edits this data, the json files are updated via Amazon Web Services, API call.
An example of the implemented URL format would be: https://s3.amazonaws.com/bucket_name/opponent_list/user1.json Here “user1.json” is a random name, so users cannot loop through others users opponent or locations, by randomly guessing names.
Once the user clicks save, the data is sent to DynamoDB datastore via Amazon Web Services API. Admin can also update these logs or delete them via API calls.
