An area for improvement in AWS Device Farm is that it lacks a lot of features that would tie it in with other AWS services. The solution doesn't have great connectivity with other services offered by AWS, for example, AWS Secrets Manager. This should be improved because a lot of times, that missing functionality hampers the quality and engineering standards in terms of deploying the full AWS suite of services.
What I'd like to see in the next version of AWS Device Farm is for it to link better, or have some type of enrollment that would tie it in with other AWS services, such as EventBridge, Lambda, Secrets Manager, and any other new service from AWS.
