Serverless architecture allows backend web services to be implemented on an as-needed basis. Rather than needing to maintain your own server configuration, architecting your software for serverless providers can minimize the overhead involved. Serverless applications are typically deployed from a Git repository into an environment that can scale up or down as needed. This tutorial will cover some best practices for writing an example serverless function.
