It seems that most if not all existing providers of enterprise-grade managed Nextcloud hosting have 1 standard server image which is just a clean install of Nextcloud without any custom apps, or with maybe a predefined set of apps enabled.
A client of ours is looking to use a managed instance of Nextcloud, but with the “Solid” app enabled. Are there any enterprise-grade hosting providers who would agree to enabling this app without breaking the warranty?
For this purpose, we are in the process of hardening the Solid app, and we will get an independent security review. Still, so far, all hosting providers we talked to are only willing to enable the default apps, they say enabling custom ones would make the system too complex for them to still provide their usual SLA guarantees.
