We migrated from containers to serverless (Azure Functions in our case). This removed a large amount of complexity from our architecture and we are pleased with the result. It is always a question of tradeoffs, serverless has its own issues but overall it has worked out well.

Was there a big cost difference?

[BaronSamedi]

It cost a bit more but not, for us, excessively more. A big upside was that we no longer had to tinker with docker and especially kubernetes. This allowed us to focus almost entirely on delivering functionality (and reliability and security) rather than infrastructure. It's always a matter of tradeoffs.
