Languages
Supported programming languages and runtime images.
When creating a serverlet, you choose a runtime image, which represents a pre-built environment for your applications. Each image supports multiple programming languages at certain versions. Itβs based on Ubuntu 22.04 LTS, in the latest version of the futrou/serverlet image, currently 2.91.
Architecture
All serverlets run on the AMD64 (x86_64) architecture. Compiled binaries with the necessary libraries for this platform work regardless of the chosen image or language.
