How Acquia helped scale API calls for Major Train Operator

Last year, a major train operator in the Eastern US region came to us and asked to help build a system on Acquia Cloud for their train API. They wanted to open up their train schedules, arrival times, delay timings, all that information for everyone. This meant that the infrastructure behind the API had to withstand a huge flurry of requests every second, while remaining very responsive. And in the meanwhile we also had to make sure that only authorized applications can access this API, applications that this operator approved.
