Hosing ERPnext with professional package

Hello folks,

We heard ERP next is providing free infra for hosting if we opt for professional services.

  1. Please share your experience on hosting provided by ERPnext itself.
  2. On which cloud( like AWS, Azure etc…) its hosted, how data backups & snapshots managed/restored
  3. Will they provide Service health dashboard & alerting on availability of cloud instance
  4. Any details/documents/certification about Infra security
