Session Handling for 1 million requests per hourThe ProblemWe have a varied and distributed server stack that uses three different languages along with 50–100 EC2 instances running at any given time. We handle about 20 million requests a day with more than a million requests at peak hours. Most of these requests (75%) are authenticated requests i.e. they hit a session store. This made us re-evaluate our session store to be maintainable as well
