Take the State of Serverless Survey 2020

Community and industry surveys often throw up some interesting results, so we tend to link to a few throughout the year, particularly if the results are going to be shared with the community.

This time we're supporting the Coding Sans State of Serverless Survey 2020 (not to be confused with Datadog's State of Serverless 2020) so if you have several minutes spare and can answer a handful of questions, you can take the survey here.

We look forward to digging into and sharing the results once they're out.
