The primary aim of the engineering team is to ensure that minimal resources are used in the day to day running of any system designed and deployed. We had faced a similar issue where our deployed system was being used to serve over a million users on a daily basis with spurts of users coming in a sporadic manner. This meant that only deploying multiple servers or scaling them wouldn’t be an optimal solution. ...
