I usually establish IaaS LAMP environments with non rolling-release Linux OSs such as Ubuntu/CentOS but I consider using rolling-release ones like ArchLinux instead.
it might be more efficient to me (both performancelly and financially) than running a Vagrant on either say a minimally-utilized Debian stable (that is, a Debian stable with nothing installed on it besides a small bash script to automatically release_upgrade it each time a new release upgrade comes out, and Vagrant), with a continuously-upgraded Vagrant-Ubuntu on top as my LAMP).
I assume so because than I'll have just one OS and not 2 and will also not use Vagrant) so I would save a significant amount of resources per popular budgets (5$-30$ / USD).
I could instead use some PaaS plan of course, but I fear a bit because their pricing is usually dynamic and as for now I don't feel comfortable enough to use them from the fear of making architectural and financial mistakes.
Assuming one can combine ArchLinux with Ansible; is ArchLinux + Ansible for an all-default LAMP generally stable?
