Subject Re: Airflow & AWS Lambda Tutorials?
Date Thu, 23 Aug 2018 21:13:30 GMT
Hey Andrew -

My suggestions are similar to Marcel's.

I favor invoking the Lambda function with the invoke
<https://boto3.readthedocs.io/en/latest/reference/services/lambda.html#Lambda.Client.invoke>
call in boto3 in a PythonOperator, or using the AwsHook if that abstraction
adds value here vs calling boto directly.

I second that using the SimpleHttpOperator in Airflow to hit the Lambda
function like a REST API is a reasonable alternative.

Personally, I would also recommend using a serverless framework such as
Zappa or Serverless as in my experience, there's a surprising amount of
boilerplate involved in writing, deploying, updating, and maintaining
serverless functions (+ API Gateway etc).

If you're considering Lambda alternatives, I think the Zeit Now Serverless
Docker Beta <https://zeit.co/blog/serverless-docker> is a pretty cool and
very easy way to run serverless functions.  There's a Hello World Flask
example <https://github.com/zeit/now-examples/tree/master/python-flask>
that shows how it all works in just a few lines.
