I'm sure as a percentage of deployed products or services that a full serverless architecture is miniscule. What I have seen in production are systems made better by use of certain AWS/Lambda integrations. One crisp example of this is with S3 storage of images. When each new image it pushed into S3, S3 kicks off a Lambda function which resizes the image into thumbnails. This S3+Lambda system replaced a much more involved image processing pipeline with EC2, queues, a data store, etc. The end result was a system much easier to manage, support and reason about.
