The easy setup of Lambda functions made me feel comfortable in coding them as it would be very similar than my PHP or nodejs application development experience which I've used earlier for AWS products only (S3). It makes our lives easier by providing us readymade solution when we need one like uploading files from S3 bucket directly into Cloudinary without any hassle! As mentioned before there are some limitations regarding resources allocation per environment/region but still its worth considering if you're not familiarized yourself well enough yet with all its features. A bit more documentation might help newbies get started faster especially about cloud-to-cloud copy feature between environments where they can just click Copy function code button instead of writing long command line arguments every time manually through terminal emulator window. We were looking forward towards deploying realtime streaming lambda services while using API gateway so that user could consume data easily via simple SDK provided APIs rather then having their own serverside implementation to do this job.
