Scale to Zero with Spring + GraalVM or WebAssembly

Cloud infrastructure can be costly and resource-intensive due to idle server instances. This talk explores two methods for deploying Kotlin web applications in a scale-to-zero fashion, offering more flexibility than traditional Serverless platforms. Sébastien Deleuze will demonstrate how Spring Boot 3.0's GraalVM native support allows compiling Kotlin/JVM applications into instant-starting, memory-efficient native executables and optimized container images. Additionally, the presentation will investigate the potential of WebAssembly as an alternative to container images for deploying Kotlin workloads to the cloud and edge, using Kotlin/Wasm and an experimental project called KoWasm to build server-side applications leveraging WASI.
