I am interviewing at tech companies and everyone is really interested about scaling.<p>I would describe myself as a competent software engineer but I haven&#x27;t ever had to deal with massive scaling of a web app, the pitfals and etc.<p>I do have some apps running on aws and heroku but they don&#x27;t serve massive traffic.<p>One thing that everyone seems surprised is when I say I use postgres, seems to be a bad thing because it doesn&#x27;t scale.<p>I follow the 12factor app best practice&#x27;s, what else should I need to know and where do I learn it ??<p>Thank you
