Serverless architectures are becoming increasingly popular, and with good reason. In my experience, container-based orchestration frameworks have a steep learning curve and are overkill for most consumer-facing companies. With FaaS architectures, like AWS Lambda and Azure Functions, in theory the
only devops you need is bundling and uploading your app.
This article will walk you through setting up a Google Cloud Function in Node.js that connects to MongoDB. However, one major limitation of stateless functions is the need to establish a separate database connection every time the stateless function runs, which incurs a major performance penalty.
Unfortunately, I haven't been able to figure out how to reuse a database connection in Google Cloud Functions, the trick that works for IBM Cloud,...
