Re: Serverless?
Is it though?
You leave a server running with AWS over a month with a set of Devops monitoring it can you realistically say that that is going to be cheaper than using a serverless approach?
If you have a Lambda that acquiesces between invocations it will always be cheaper.
To prove the point I wrote a dumb IG trading bot based solely off the free tier Lamda - yep - I made money from nothing...
I will accept that you may need to spend some time/money to refactor parts of your code base - but thats a one off cost.
