If you don’t want to pay extra cost for hosting, then Serverless is a great option for you! In a Serverless world where you pay-per-trigger, you don’t need to write on/off scripts, plan reservations, or plan for spikes. You just pay for what you use! With FaaS each function is hosted by the FaaS provider (AWS, Azure, DigitalOcean, etc.) and can be scaled automatically as function call frequency increases or decreases. This turns out to be a very cost effective way of paying for compute resources. NordWhale implements Serverless solutions using AWS LambdaAWS, Cognito Users Pool, AWS API Gateway, Serverless Framework, DynamoDB, etc.
