Interact with MongoDB in an AWS Lambda Function Using Go

If you’re a Go developer and you’re looking to go serverless, AWS Lambda is a solid choice that will get you up and running in no time. But what happens when you need to connect to your database? With serverless functions, also known as functions as a service (FaaS), you can never be sure about the uptime of your function or how it has chosen to scale automatically with demand. For this reason, concurrent connections to your database, which aren’t infinite, happen a little differently. In other words, we want to be efficient in how connections and interactions to the database are made.

In this tutorial we’ll see how to create a serverless function using the Go programming language and that function will connect to and query MongoDB Atlas in an efficient manner.
