The first useful check
The offered images are Debian 13, Ubuntu 24.04 LTS, Ubuntu 26.04 LTS and AlmaLinux 9; they are operating-system choices, not preinstalled applications.
Inputs and prerequisites
Read your runtime, database and proxy documentation for the versions you intend to use. Consider the package ecosystem your team can maintain and the upgrade path you can explain.
A small, reversible procedure
Select the image that matches the app’s supported instructions, then record the version and first package decisions. Keep the first release small enough to test access, logs and recovery separately.
What to record after the check
Save the selected image, runtime version, package source and a simple rollback or rebuild note.
Scope and service boundary
An image selection does not guarantee application compatibility, a supplier image revision or ongoing package availability. Malaysia, Romania and Switzerland are server-country choices; they do not establish a backup country, facility detail, stock or measured network result.
