Tools like AWS’s Lambda, Google's Cloud Functions, and many others are allowing us to create “serverless” applications. At Bustle (a top 30 website in the US) we are taking full advantage of this new infrastructure. APIs, databases, searching, indexing, server side rendered javascript, are all being handled without deploying any of our own servers. And the best part? It costs orders of magnitude less than our old VM based deployments. I’ll walk attendees through our entire serverless stack. I'll talk about the good, the bad, and the ugly. I'll share real numbers from production systems. The goal is that attendees will leave with concrete knowledge of what going serverless really means and be able to decide if it makes sense for their own infrastructure.
