It still lists 5.4 as version, but whatever.
For hosting maybe OVH SAS may be a good hoster, or you could take a look at Microsoft Azure maybe, not the cheapest but
pretty secure, Microsoft is working hard on it.
Google Cloud Platform is commercial-use only, but the most secure Cloud Platform you can get right now and also one of the fastest.
There are also good hosts in germany: HostEurope, Hetzner Online, STRATO and some more maybe.
Oh and when you get a dedicated host, implement a CDN (My recommendation is Incapsula), an SSL Certificate, and maybe use Nginx, IIS or best on Linux i guess LiteSpeed as web server (Theres a free and a paid one)
