sorry but Rekognition rekt it for any type of computer vision on AWS.
Great infrastructure...after all I do have an AWS Solution Architect Associate certification....which means jack shit
Great move by GCP, I'm also very pleased with Firebase and it's integration with cloud functions....
BUT my biggest reservation still in 2018 when it comes to serverless is the cold start up time...
I built a token based API on AWS Lambda and registering, signing up took forever when the app was not at peak. that was 2014 tho.
