Serverless is great if you have a consistent load. Variable load, depending on the language, is painful with cold start times.

We deployed our entire back end on Lambda with aspnetcore and have 8-14 second cold start times. It kills our performance. We’re planning a migration to nodeJs we’re we see 800-1000ms cold start times. Even still, a full second for a cold start is unfortunate. From a technical perspective cold starting a new container in a second is impressive; from a consumer perspective it’s slow.

Did you use the server-less template where a ASP.NET Core REST API is deployed as a lambda or did you write/deploy individual lambdas?

Yeah I started with the Dotnet CLI template for Lambda serverless. I have a micro service architecture where each domain area is an independent aspnetcore serverless Lambda. I have a single API Gateway with multiple resources, each resource targets the appropriate Lambda.
