The speed of deployment can be changed by limiting the size of the uploaded app, limiting the complexity of the build necessary in the Dockerfile, if present, and by ensuring a fast and reliable internet connection.

Note: Alpine Linux is built around musl libc and busybox.

This makes it smaller and more resource efficient than traditional GNU/Linux distributions.

A container requires no more than 8 MB and a minimal installation to disk requires around 130 MB of storage.

Not only do you get a fully-fledged Linux environment but a large selection of packages from the repository.
