Launched a new app for client 3 weeks ago on AppSync, 5,000 users later, 100,000+ API calls per day, 99% cache hit rate, 0 problems, and 90% of AWS cost is on AppSync cache (T2.Small). Easily one of the most complex things I've ever built (in a few weeks). Gotta love #serverless! pic.twitter.com/fjJiBY9Ftf
