Have used it in production for > 2 years, mainly for ETL/Data processing type jobs which seems to work well. We also use it to perform scheduled tasks (e.g. every hour) which is good as it means you don't have to have an EC2 instance just to run cron like jobs. The main downside is Cloudwatch Logs, if you have a Lambda that runs very frequently (i.e. 100,000+ invocations a day) the logs become painful to search through, you have to end up exporting them to S3 or ElasticSearch.
