9 Serverless Functions

Traditional frameworks like Grails and Spring are not really suitable since low memory consumption and fast startup time are critical, since the Function as a Service (FaaS) server will typically spin up your function for a period using a cold start and then keep it warm.

There are generally 2 approaches to writing functions with Micronaut:

The second approach is only for HTTP functions and is useful for users who want to take a slice of an existing application and deploy it as a serverless function. If cold start performance is a concern it is recommended that you consider building a native image with GraalVM for this option.
