Serverless is widely lauded as the ops-free future of deployment. Serverless is widely panned as a gimmick with little utility for the price. Who’s right? And what does it mean for my Rails app? This session takes a critical look at serverless hosting. We’ll consider the abstractions underlying environments such as AWS Lambda and Google Cloud Run, their assumptions and trade-offs, and their implications for Ruby apps and frameworks. You’ll come away better prepared to decide whether or not to adopt serverless deployment, and to understand how your code might need to change to accommodate it.
