Need
I wanted to host and tests some apps before publishing/use it on internet. The physical server hosting are light, small and silent. The solution must not consume a lot of ressources.
The client wants to rely on this service so emails can go through and alert teams on time. The service must be available or alert people in case of failure.
I needed a book library centralized and always available. Online reader and download option must exist to use my favorite mobile reader or easily open the book in a new tab.
