Hi Andy,
probably OT, but anyway.
We are only in production. Every single day in a year without (hopefully) any break in IT. Would this happen, no ERP, nearly no machine would run, no telephone, no banking, I don’t have to go in details.
And yes - security updates for the OS I do take serious. Therefore the uptime of our servers cannot beat yours. You wrote elsewhere (in this forum), how long servers are running which you maintain. AFAIK there are kernel updates which require a reboot. Nevertheless I bet: none of your maintained servers have ever been hacked. Am I wrong?
What do you mean with single use?
In a hybrid world the desktops (also software for machines (better interface between human and machine) - printers, drilling machines, …) in a company are usually (>90%) MS$ systems. Sometimes apple OS also. (Well, hmm, I confess, we still have SIEMENS (SINUMERIK) controls on machines…) but this is another world.
What I see at this point, if running a linux server, samba (share/ibay management) seems to be essential. Maybe with active directory or not. Besides an easy management for users and groups. Next would be email. To manage and for the users, it could be something like webmail, roundcube, SOGo but also i.e. thunderbird, whatever. Sometimes something is historically… Easy management (for admin and users) is highly appreciated. At glance with all features to make email as safe as possible. Database(s). Groupware for most companies… There are surely other and more needs for other business.
Right now (for us), assuming properly configured, it’s pretty safe to run all this on a common linux NS7 server. We’ve never been hacked or compromised. The server was built as “shoot and forget”. To be very clear - this is meant with my statement “never touch a running system”. But of course with all recommended security updates in first place for the OS, and if announced also for the installed software.
For me this is the SME idea. Remember MITEL. All I see is that the child NS8 needs much more attention in many directions. Only spoken for me.
Cut this now - it’s really off topic. Sorry for jumping on.
