Being a pioneer in a field most of the time gives you a boost when you are showing your portfolio. It is enriched with lots of fancy and buzz words and when you talk with your friends and colleagues you sound as you are talking rocket science and you look smart. And that is a good thing. On the other side, you have a lot of hidden traps that you need to overcome when working with new architecture technologies. In this talk I will present the architecture that me and my team created on top of AWS. The architecture currently is serving millions of users on daily basis with 90%+ score in every performance test. It consists of 15+ services that are provided by AWS. The presentation will focus on all of the good things and the problems that we are facing while using AWS services.
