A Netflix eng manager once told me that "It'd cost 7x to run Netflix if Netflix ran on Lambda". But what he said next was even more insightful. "But, not everything at Netflix runs at Netflix scale." And that is true for most enterprises. When I was at DAZN, we didn't operate at Netflix scale, but we still had to deal with millions of concurrent users at peak. Services along our critical path will experience sudden spikes from hundreds reqs/sec to tens of thousands reqs/sec in a matter of seconds. But outside of the critical path, Lambda was used heavily across many workloads. And even some services on the critical path were able to use Lambda and API Gateway because their API responses were highly cacheable. Here's a quick rule-of-thumb from a throughput POV: * Stable high-traffic workloads => containers * Bursty, occasional workloads => lambda And don't forget about caching. It's literally a cheat code for building scalable and high-performance systems! ------------- Lambda cold starts getting you down? 😮💨 Get my 8-day email course to help you better understand Lambda cold starts and how to mitigate them.
