Yes, I am not the author of the article though. I just shared it because I always wondered if Lambda was good enough for hobby projects and how much it would cost. Generally, 2 million API calls per month will come around Max 10 requests per second (considering peak times as the requests will not be spread out evenly over time). Even a self-hosted $10 Digital Ocean instance could handle it with Node.js. But the way the author has set up his application, getting started with highly available infrastructure with highly available DB with a possibility of 100 concurrent lambda executions is interesting. And one can get started with this in $11-$12 is very interesting indeed.
