Who are the best hosting providers for Drupal 8 that guarantee as close to 100% uptime as possible? 

I am familiar with Acquia but would be interested if others have had positive experiences with other Drupal 8 hosts. 

I'm particularly interested in enterprise level service with strong support and/or data centres located in Australia.

After extensive self taught i have finally managed to design my first website for a school i currently work. Now uploading it to internet so anyone can see what we do. Am stuck.
Please if anyone is reading this kindly recommends a good hosting platform and easy to do it on your own tutorials with less technical jargon so that i can post the site to online for my school.I use DRUPAL CORE 7.

Please help me
